NASA plans improved ‘Internet in space’ - references SDR's

NASA plans improved ‘Internet in space’ * By Sean Gallagher * Mar 09, 2009 NASA’s Deep Space Network is on the way toward becoming a true Internet in space, thanks to the agency’s research and investment in software-defined radios (SDRs). Also, the agency is preparing an SDR test module for the International Space Station that will be capable of connecting the station with an uplink of 100 megabits per second. Pat Elben, the chairman of NASA’s software defined radio architecture and technology team (SAT) at NASA’s Space Communications and Navigation directorate, told attendees at the IDGA’s Software Radio Summit that the agency is setting up a new test platform. The platform, named the Communication Navigation and Networking Reconfigurable Testbed (CoNNeCT) will help NASA test waveforms based on the agency's Space Telecommunications Radio System (STRS), NASA's own standard for space-rated software-defined radio systems. CoNNeCT will be added to the International Space Station in 2011, and demonstrate communications between the space station and the Tracking and Data Relay Satellite constellation that makes up the backbone of NASA’s network with three radio systems -- the Electra radio that flew aboard MRO, the General Dynamics Starlight radio, and the Orion radio -- the system being designed for NASA's follow-on to the space shuttle. NASA developed its own standard because of the demanding requirements of space, where reprogramming a radio often has to be done remotely while the radio is on a spacecraft traveling through the solar system. That was the case, Elben said, when the Mars Reconnaissance Orbiter (MRO) was launched. Technicians discovered the Electra radio aboard MRO, a software-defined radio that was to act as the communications link to the two Mars rovers on the surface, was getting interfered with by something else on the spacecraft just before launch. NASA was able to launch the MRO and create a software patch and upload it to the Electra radios aboard it while the spacecraft was en route to Mars, he said. Some observers have expressed concerns that suppliers might be reluctant to write software to yet another SDR architecture — the Defense Department’s Joint Tactical Radio System uses the Software Communications Architecture, which has been adopted by the Software Defined Radio Forum along with its own SW Radio standard. Elben said NASA plans on buying more than 1,000 STRS-based radios between now and 2025, but the price of these radios — between $1 million and $5 million — makes STRS radios a potentially $1 billion market for radio developers. Although NASA has deployed software-defined radios for years, starting with the “Blackjack” global positioning system receiver on spacecraft in 2000, STRS will be part of the basis of an ambitious revamp of the agency’s Deep Space Network. The re-engineering will be based on SDRs and on high-bandwidth optical links, Elben said. It will also entail the use of software-defined systems and a move to less-expensive arrays of dish antennas instead of the old larger dishes. The new approaches are expected to make the network more automated and less expensive. In the 1960s when NASA first created what became its Deep Space Network, “there was no grand vision,” Elben said. “NASA’s goal for 2024 is a highly integrated, IP-based disruption resistant network.” Last November, NASA successfully tested Disruption Tolerant Networking (DTN), an Internet Protocol-based network using store-and-forward technology to ensure that packets of data would not be lost when being passed through the Deep Space Network. The agency will begin testing DTN aboard the International Space Station this summer. Source: http://gcn.com/articles/2009/03/09/nasa-software-radios.aspx?s=gcndaily_160… ###

Re: QSL Etiquette
by Luc Leblanc 16 Mar '09

16 Mar '09

Satellite does not lie (Human does) Something came up to my mind. i received a QSL card for a satellite QSO one year prior to the date i get the card. And for an unexplainable reason this QSO was not in my log. We have another tool available to check if with the time reported on the card this satellite was at least in view at that time. Just set back your pc clock around the past date and play with you program to see if it's matching a co- visibility foot print. It was not but when i try local to UTC time switch it does. This fellow discharge himself from his burden of proof and he got my card but not before he sends me a corrected one.

Re: PREDICT for DOS configuration question
by Alan Sieg WB5RMG 15 Mar '09

15 Mar '09

WA4SCA said : > , so now to figure out the scheduling. As I recall (without looking) the InstantTrack method, something like 000B045S090B270 would indicate mode B from 000 to 045, mode S from 045 to 090, back to B, etc for an orbital schedule, but as Greg says we don't have any of those. Maybe a test of something like that would at least show if the format was similar for Predict. I can't think of what else it might be useful for. I don't think we have any that would use a weekly schedule either, but I understand the general query to find the formats ... With source code in hand (on screen), I'm sure someone (with more time on their hands than me) could figure out what it was looking for, and how it was formatted. .. Or someone might show up and just tell us. Good luck Alan... /;^) -- <- Licensed in 1976, WB5RMG = Alan Sieg * AMSAT#20554 -> <- http://www.somenet.net * http://wb5rmg.somenet.net -> <- http://www.linkedin.com/in/alansieg * My 'Day Job' ->

WD9EWK @ Scottsdale AZ hamfest - report
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Mar '09

15 Mar '09

Hi! The 2009 Scottsdale Amateur Radio Club's "Springfest" hamfest was this (Saturday) morning, and AMSAT was present once again. The hamfest, held at Scottsdale Community College in Scottsdale AZ (technically, on the Salt River Pima-Maricopa Indian Community reservation east of the Scottsdale city limits), is usually the largest and best-attended of the various Phoenix- area hamfests in the hamfest "season" here - any time other than summer. A good location at the end of one row in the college's parking lot, and a great turnout, made for a successful morning. I set up an AMSAT table at 0500 local (1200 UTC), and was able to get on an AO-51 pass at 1245 UTC. Thanks to the 14 stations from Maine down the eastern half of the USA and HI8LAM in the Dominican Republic for QSOs during that early (for me) pass. Later, I worked the next AO-51 pass around 1424 UTC, logging 14 more QSOs. Stations from British Columbia down through the USA (thanks K8YSE, for being the station furthest east on that pass!) and into Mexico were worked. I was on the FO-29 pass around 1525 UTC, hearing stations clearly on the downlink around the area I hoped to be on, but could not hear myself through the satellite. I don't know if it was a case of the satellite's uplink antenna(s) pointing away from me or if I need to take a closer look at my setup. In any event, I had a crowd for that pass, so we listened as I fielded questions about this satellite and SSB satellite operating. Around 1710-1730 UTC, I had 3 passes to choose from - FO-29, SO-50, and VO-52. All were good passes, but I went with VO-52 so I could work stations on an SSB satellite for one of my demonstrations. Thanks Mark WA8SME and Glenn AA5PK for showing up and chatting for a couple of minutes. If anyone who worked WD9EWK during these passes wants to get a QSL card for those contacts, please e-mail me directly. I'll be happy to drop a card in the mail for you. Some of the contacts will have QSL cards dropped in the mail with SASE, since they were new grids and/or states/countries worked via satellite. :-) I did not work alone this morning. Gerry VE4GTB/KD7MDB, who is from Winnipeg but spends winters in the Phoenix area, once again showed up at the hamfest. As always, many thanks for helping the AMSAT efforts at yet another Phoenix-area hamfest in your retirement days. :-) Larry W7LB came up from Tucson, and Ray W1OTH was down from Prescott, spending time at the table and also walking around the hamfest. Ray acted as my "antenna rotator" for the VO-52 pass, which went almost directly over the hamfest. All of us chatted with whoever happened to stop by the table, answering questions throughout the morning. Thanks for all the help! The Scottsdale Amateur Radio Club has been very accomodating to AMSAT for the times I've been part of the AMSAT efforts. This is the 3rd year I have been with an AMSAT table at this hamfest. Thanks to Ed WU7S, the primary contact for the club's hamfest organizing committee, and the club for the space at the hamfest. And many thanks to the stations making 30 QSOs with WD9EWK during the morning. Until the next demonstration... 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Mario was a very senior scientist/engineer at NASA Goddard where he made his name by providing magnetometers for nearly every deep-space and planetary mission since the 1970's. Tom recalled, "When a young Martin Sweeting wanted to fly magnetometers for navigation on the earliest UoSAT's, Mario was the 'go to' guy that put Martin on the right track. Since magnetometers are biased by metal and electrical currents in a spacecraft, Mario arranged for testing of the early UoSATs." Tom also recalled Mario's assistance with the Phase-3 program, "When Jan King, Karl Meinzer, and I were trying to minimize radiation damage in critical Phase-3 components (like the IHU and CMOS logic), Mario was our mentor in helping to figure out the best way to minimize damage and teaching us how to apply tantalum to the top and bottom of ICs."

March 15, 2009 To All RADIO AMATEURS BID: $ANS-074.04 AMSAT-DC Area Coordinator Pat Kilroy, N8PK reports on plans for the AMSAT-DC Workshop to be held on Saturday, April 25, at the NASA Goddard Space Flight Center in Greenbelt, Md. A small "simulated satellite" kit will be built, tested and operated by individuals attending. The completed kit, soon to be widely known as a PICetSat II module, is a simple remote sensing unit that serves as an expendable high-altitude small balloon payload. It transmits downlink telemetry on the 70 cm Amateur Radio band. Other attendees will provide and configure radios, computers and software needed to receive, decode and analyze the PICetSat II telemetry. Pat says, "The format of this year's workshop is an experiment unto itself for the few AMSAT-DC subgroup of members who are attempting to organize such an event for the first time." He adds, "This workshop may prove to be a fine training opportunity for one to learn the basics of the design, construction, testing, calibrating and operating an earth-orbiting satellite. All of this in one long Saturday of fun!" The planning sessions are being held each Thursday evening via a toll-free telephone conference. If you wish to help organize or execute the workshop then contact Pat by e-mail for the details of connecting with the group on the telecon at Patrick.L.Kilroy(a)nasa.gov as soon as possible. The cost of each kit will be determined soon, along with the admission structure. For example, being evaluated is $90 for a kit plus AMSAT membership if one doesn't already have it. The details of the registration process, workshop procedures and the associated costs are to follow in a later bulletin and on the AMSAT-NA and AMSAT-DC web pages.

School Contacts An ARISS contact was held with the Da Vinci Science Center in Allen- town, Pennsylvania on Saturday, March 14 via telebridge station WH6PN in Hawaii. Students submitted questions to ask the ISS crew through the Center's Teacher Leader Institute. Eighteen students with the best questions were selected to speak with the astronaut and all students were invited to attend this educational activity. Parkside Community College in Parkside, Cambridge, U.K. has been scheduled for an ARISS contact on Monday, March 30 at 16:54 UTC. Station GB4FUN will handle the connection. The Girls' Middle School (GMS) in Mountain View, California has been scheduled for an ARISS contact on Monday, March 30 at 18:16 UTC via telebridge station K6DUE in Maryland. The contact is planned with spaceflight participant Charles Simonyi, KE7KDP/HA5SIK. GMS is a small, independent school for girls in 6th - 8th grade. The school's mission is to nurture and empower girls during this pivotal time in their lives. It looks for non-traditional educational opportunities to help girls expand their horizons. An ARISS contact has been scheduled for Marcelino Canino Canino Middle School in Dorado, Puerto Rico. The contact will take place on Tuesday, March 31 at 15:29 UTC. A Microsatellite Student Program has been implemented where students design, construct, build and launch microsatellites which are then tracked and recovered with the help of amateur radio operators. Milwee Middle School in Longwood, Florida has been scheduled for an ARISS contact on Wednesday, April 1 at 17:48 UTC via telebridge station ON4ISS in Belgium. Carl Sandburg Elementary School in the Lake Washington School District, Kirkland, Washington has been approved for an ARISS contact. The con- tact is slated for Thursday, April 2 at 19:28 UTC, assisted by tele- bridge station W6SRJ in California. 2. Padthaway Contact Successful On Tuesday, March 3, students from Padthaway Primary School in Padthaway, Australia participated in an ARISS contact.

PREDICT for DOS configuration question
by Alan P. Biddle 14 Mar '09

14 Mar '09

I have been looking at PREDICT for DOS, and have a question about configuring individual satellites. A typical entry looks like this: AO-16 07530 No alat/alon Mode VU Transponder 145.850, 145.950 29.500, 29.400 No weekly schedule No orbital schedule end That seems to imply that you can enter schedules, but none of the examples provided provide any format information. Can someone confirm this, and if so, give me a pointer to documentation, or even an example with weekly and orbital schedule shown? Also, if you have an alat/alon, do you just enter the numbers such as 0/0, or does it require something else on the line? TNX, Alan ----------------------------------- Who is John Galt?

QSL Etiquette
by Ian 14 Mar '09

14 Mar '09

I was wondering what others may be doing when they receive an "questionnable" request for a QSL. Last week while on vacation in Orlando I attempted to make some AO51 contacts with a handheld station. Althought I was receiving many stations, I was unsuccesful in establishing a contact and never heard anyone call me back. I must have been getting out though as I have received an eQSL request from a South American station. Is it normal practice to ignore the request or to reply with refusal to QSL. If it were a mistaken callsign situation I would reply with a "sorry" but in the case of a bogus request I was wondering what others may be doing. Next time I will use a better antenna hi hi.

QSL Etiquette
by John W Lee 13 Mar '09

13 Mar '09

Guys, As a little background, I have been a ham for over 50 years and QSL'ing has been a big part of my activities since they are required for awards. And I just plain like QSL cards! I respond to every card that comes to me. There are so many messages from people who say they don't have time to QSL, etc. When I was a QSL manager (see below) I was working full-time, had a 2 hour each way commute, was married with 2 kids to raise. I was one of the QSL managers for the YASME DXpeditions of the 1970's. W6KG and W6QL went to many countries during that period and made between 8000 and 10,000 QSO's at each place. The logs were all hand-written and in 3 ring binders for each location. QSL cards would come in the mail in big bundles with rubber bands around them daily, and the bureau cards would come in cardboard boxes of maybe 25-30 pounds via UPS! I found LOTS of people who were NOT in the log! And I really tried to help them by looking at different days, different times because they put the wrong time/date on them, etc. And I was able to find a lot of them that way. Some people have not yet learned to use UTC time/date. This is a must. If I couldn't find them anywhere in the log, I'd just write "Sorry, not in the log" on their card and send it back. That way they would know that their card made it to the manager and didn't get lost in the mail. Of course good logging is a must also. I have every logbook from day one of my ham career. They are archived in boxes but I can pull one out and check for something if I need to. And I have received cards 10 years or more after the QSO. I keep about 5 year's logs handy, as well as having a log in the computer which I back up at least monthly. If you work somebody and you don't get the call or don't think you have it correct, by all means ask the person to give it again (slowly or in phonetics, whatever it takes)! A legal QSO should contain the time and date, other station's callsign and some other bit of information such as a signal report, grid locator, name, QTH, etc. What did we do before E-mail? We copied everything down correctly ! We did not write to somebody asking for their callsign or wondering if we made a QSO. Regarding E-QSL and LOTW, with E-QSL, if the QSO information matches, you get a confirmation. You can "fudge" and confirm a contact that is not in the log. This is not good. With LOTW you can't. If the information does not match. If you are new to QSL'ing or new to ham radio, I hope this helps you. 73, John K6YK then there is no confirmation. That's the way it should be. ____________________________________________________________ Free information on Digital Photography.

QSL Etiquette
by Darin Cowan 13 Mar '09

13 Mar '09

If you didn't log the QSO, then reject the eQSL with a note that says "not in my log"... That's what I do. It happens sometimes when condx are marginal, like you're describing. It's probably a bit disappointing for the person at the other end, but sometimes that's just the way things work. I'd rather keep my logs relatively accurate. Whether or not the request is truly bogus is sometimes hard to judge. Did the person make this up, or did he mis-copy the callsign: maybe he had a QSO with VE3OIG and wrote J in his log by mistake? Or because I mostly work digital modes, maybe noise munged the call a bit on his end and he didn't notice. Don't chalk up to malice what can be easily explained by error or incompetence :) For satellite contacts, a person like me who has less-than-perfectly-functional hearing may misinterpret an E for an A, an F for an S, an M for an N and so on. This is exascerbated when people don't use proper phonetics, so it happens that I mis-copy callsigns far too often for me to be happy with. I've had QSLs sent back from people who didn't know what the card was for simply because It went to KW#XXX instead of KD#XXX or DE#YYY instead of DA#YYY. And that's not calls I think are questionable... those are honest errors where I'm convinced I got it right. If conditions are marginal and I'm not truly sure, I tend not to QSL and will leave a sticky note on my desk for about a month. If I get a QSL with information matching a note, I give the benefit of the doubt. Otherwise, I periodically clean up the notes and then the information is forever gone as if it never happened. I've only ever received a handful of truly bogus QSLs, and they've all been SWL. In each case, the sender clearly read spots I put on the DX cluster and sent me a QSL as if he heard me in a QSO with the station I spotted. Those go straight into the shredder without comment. Now I reject SWL QSLs for anything that shows up on a cluster, even if it is valid. 73 de VE3OIJ -Darin -----Original Message----- From: "Ian" <Ian(a)mceassociates.com> Subject: [amsat-bb] QSL Etiquette Message-ID: <E06287B5F4054BFC8818E16E99D2FDF0@ian57229053685> I was wondering what others may be doing when they receive an "questionnable" request for a QSL.

WD9EWK @ Scottsdale AZ hamfest, Saturday (14 March)
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Mar '09

13 Mar '09

Hi! I will be part of the AMSAT table at the Scottsdale Amateur Radio Club's "Springfest" hamfest on Saturday, 14 March 2009. The hamfest is at Scottsdale Community College, east of the AZ-101 freeway exit 46 on Chaparral Road in Scottsdale AZ (grid DM43bm). It starts at 0600 local (1300 UTC), and runs through midday. During the morning, I will be on various satellites doing on-air demonstrations. Look for WD9EWK on AO-51 and possibly some of the other satellites (SO-50, FO-29, VO-52). I have visible passes on the last 3 satellites in the 1700-1800 UTC hour, and I don't know which pass or passes I will attempt. If I am on VO-52, I will try to put myself around 145.910-145.915 MHz USB on the downlink. For FO-29, I will try to be around 435.865-435.870 MHz USB on the downlink. Please give me a call if you hear me during any of these demonstrations. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

QSL Discrepancies

Hi all, I just received a QSL card today from KB0RZD but the date and time don't match what I have in my log. I've looked for an email address but have been unable to locate one. How do members usually handle a situation like this? My log shows the QSO as being on 8 March 2009 between 13:29 and 13:30 UTC on AO-51. His QSL indicates the QSO was 7 March 2009 at 14:11UTC. I have no record of any contacts made during that pass. Other stations contacted during this pass were W7JPI, N5ZNL and K8YSE. If any of these stations would contact me off list to help me verify my log entries it would be greatly appreciated. I mailed out my own QSLs to those I had not made previous contacts with yesterday.

ISS Temporarily Evacuated
by Andrew Koenig 12 Mar '09

12 Mar '09

I heard about this in school today when my English teacher got a text message from her Boy Friend, who works in mission control. The article is below. Astronauts safe after debris passes space station Crew evacuated to Soyuz lifeboat as a precautionBy MARK CARREAU Copyright 2009 Houston Chronicle March 12, 2009, 12:03PM The three American and Russian astronauts aboard the international space station took shelter in their Soyuz escape capsule briefly today to wait out the close approach of debris from an old U.S. commercial rocket stage, NASA said today. The debris, about 4 inches long, whizzed within three miles of the orbital outpost at 11:39 a.m., CDT, causing no damage. However —just in case — Americans Mike Fincke and Sandy Magnus and Russian Yury Lonchakov climbed aboard their Soyuz lifeboat between 11:35 and 11:45 a.m., said NASA spokesman Kelly Humphries. “We are all very happy the debris did not impact,” NASA’s Mission Control told the astronauts. The U. S. Strategy Command, the branch of the Department of Defense that tracks the thousands of active and inactive spacecraft and other man-made debris circling Earth, notified Mission Control of the close approach late Wednesday. The notice left too little time to maneuver the space station well away from the PAM-D rocket upper-stage debris, Humphries said. The astronauts train for an escape aboard the Soyuz in case of a fire, chemical leak, debris impact or medical emergency. So far, an evacuation to Earth has not been necessary.

by Alan Sieg WB5RMG 12 Mar '09

G8IFF/W8IFF said: > Which satellite prediction program do we see on the big screen > on the NASA TV broadcasts from mission control in Houston? There are several different views you may see, but the main thing that we "see" is the background map. Several "free" programs now utilize the map made from composite satellite images that looks natural and cloud-free. A good example someone pointed out is the default image in Orbitron. What sets the NASA maps apart is that they also usually show the coverage area of the three primary TDRS relay satellites, and marks on the future ground tracks to indicate orbital sunrise and sunsets. As the shuttle (or ISS) moves about the orbit, those coverage circles help visualize the "TDRSS handovers" where communications will drop out for a minute or a few. You may also notice on the ISS map view, the range circles about the Russian ground stations. During de-orbit and re-entry the background goes black and you'll see blue range circles about the various US radar tracking sites. During Joint-Ops with both Shuttle and ISS, they show Lat/Lon/Alt stats in the upper corners of the display. Lots of things they can turn on/off. The other display (my personal favorite) provides a multi-view in 3D space. I've heard it refered to as 'Birds Eye View' or BEV. I've seen similar applications running on SGI computers, with a 3 pane window... the top one a side view parallel to the velocity vector, with gravity down. The lower panes showing 1) a view from above sighting down along gravity, and 2) a view from slightly above looking forward along the velocity vector. These views are fed by live telemetry data that will include the vehicles orientation respective to those vectors. I really like watching those during orientation adjustments. If you can watch before docking, you can see how the ISS is rotated around to place the docking port 'in back' so that the Shuttle's TPS is better protcted from any orbital debris. If you see this display before re-entry you can see how they turn tail-forward in preparation for the de-orbit burn... I really enjoy watching this stuff. Still tho, it is hard to beat the 3D view in InstantTrack, especially on one of those Molniya orbits like AO-13, whippin around perigee - whoosh !

Does it makes sense to try to listen to the S band beacon on *2304.1 MHz ? Some sources say, that this beacon was never turned on when AO-7 was operational? We could use or 20m dish in Bochum to listen to it, as we are going to do some tests on S-band soon.. 73s Peter, DB2OS

Hi all! Thanks for my first QSO's via AO-27 this afternoon! Special thanks to Leo, W7JPI, for the actual first QSO and also letting me know I was making the bird alright. I just didn't hear myself well because I didn't adjust for doppler while busy with other demands with the HT and arrow. :) 73, Jeff WB3JFS

Great! Excellent! Today I made my first contacts via AO-27. The signals are clear and strong, but only few stations in the air. I worked SW6KRW and SW6KRV and heard RZ6ANF and UA6BAC on 10th March 2009. at 12.24UTC. After the FSK transmission transponder go off. Thanks to all involved in SW repair. Best regards and see you on the AO-27! Zeliko 9A2EY

Landwehr preamp
by howard dawson 11 Mar '09

11 Mar '09

Hi all. I wonder if there is anyone out there who can help me, I am trying to locate a GASFET for my Landwehr 70 cms preamp model GAAS 435ma. I have been informed that there is no equivalent as these were specially for Landwehr Electronics so it would seem that my only hope is that someone, somewhere may have a preamp that has seen better days, but still has the Gasfet intact. I have emailed Landwehr but to date no reply, Any assistance would be greatfully appreciated. 73. Howard. G0VBT.

Why RFMD parts have export restrictions ?
by William Leijenaar 10 Mar '09

10 Mar '09

Hi AMSATs, It has been some time ago that I worked on my mini-transponder again. Most of you might have seen the article about my 30grams linear Mode-UV :o) For my tests I purchase very often parts from Digikey in US, with high quality parts and fast deliveries. However, for some time I experience problems with getting parts from RFMD, which seem to have a "vendors export restriction". The strange thing is that I got the parts delivered around November 2008, but faced problems when I tried to order new parts begin this year. Does anyone know what the reasons might be for these restrictions ? And is there any way to get the parts to Europe without to much hassle. Many thanks, 73 de PE1RAH William Leijenaar ---

AO-10

one might keep in mind that the offpoint of the satellite is not known, so we in the US might have a poor offpoint and hear nothing, and those on the other side of the world may have a good offpoint and may be able to hear something. The point is, if you think you may have heard a signal keep listening and by all means keep reporting it. the more antennas pointing at it and more reports of what is or is not heard will help to know if the satellite is making a come back or not.

Re: Limits of G-5500?
by Mark L. Hammond 10 Mar '09

10 Mar '09

Hello all, Thank you for the feedback. The overwhelming consensus is that a 7-8' dish is a BAD IDEA for a G-5500, mostly because of wind load. I got some interesting links and pictures of folks with big dishes. Most "rotators" were a variation of the standard dish setup, and a few folks mentioned the Alph Spid as a viable option for such a dish. I currently have the following on my G-5500: short M2 2M array, short M2 435 array, 8 turn 435 helix, 20 turn 1.2G helix, and a 32" dish. It's a pretty full load :) Guess I'll store the dish for while and dream.... 73, Mark N8MH At 09:25 AM 3/7/2009 -0500, Mark L. Hammond wrote: >Hi All, > >Recently I acquired a 7.5' dish.
