A question came up in a local ham breakfast group. AO-7 and some upcoming launches have modes which include HF frequencies. SatPC32 supports a range of Icom rigs, and is the IC-7300 CAT set close enough to work with one of them? I know, and explained, that Doppler isn't an issue on HF, but it is an interesting question. Has anybody tried this? No guesses, please. :) 73, Alan WA4SCA

AMSAT-Francophone launches a consultation, open to all, on the amateur satellite radio service. Feel free to participate! Publié le 3 février 2019 par Xtophe

Dear Satellite / nanosatellite project managers often wish to use amateur radio frequencies for educational and outreach purposes. The amateur radio community thus offers them a tremendous potential for monitoring their fragile conception. They often ask what kind of amateur radio experience would be interesting to board a cubesat or what services they could provide with their communications systems. The answer can be simple: a transponder, but these designers would like to bring novelty and innovation. In order to provide more factual input, AMSAT-F <http://site.amsat-f.org/> has decided to launch an online survey to find out what you do and would like to do as a satellite activity, what you expect from satellite designers and what you can bring to them. *The synthesis of these results will be presented at the second* AMSAT-F meetings « Rencontre spatiale radioamateur » on 9 and 10 March 2019 in Nanterre (France) <http://site.amsat-f.org/2019/01/29/deuxieme-rencontre-spatiale-radioamateur…> Do not hesitate, give your opinion by completing the questionnaire via the link : https://framaforms.org/amsat-francophone-survey-1548716436 <https://framaforms.org/amsat-francophone-survey-1548716436> The survey is in english but hosted on French server. Few guideline could be in French. 73 Christophe Mercier AMSAT-F President

Yaesu 500 elevation rotator
by Nick Pugh 08 Feb '19

08 Feb '19

If the elevation rotator has been idle for a while it will not start in the up direction. By momentarily pushing the down switch it will move in the up direction. The rotator will work nominally for a while. Any suggestions? Nick k5qxj

Hmmm, where to begin when so much opportunity is afoot? > ... If I don't have a really good reason to put together a complex and > expensive microwave station, I probably won't do it Yes, a 10 GHz downlink can be converted into a range of frequencies covered with an off-the-shelf SDR for $100-$200. I'll admit that a microwave transmitter is more costly (for the present time) but $100 and some ingenuity to participate in one of amateur radio's next frontiers is likely within reach! Work all the grid squares, all the states, bag all the DX? I see an opportunity to make so many more friends and earn so much wall paper you'll be considering building another wall in the shack so you can display all the certificates ;-) And, you'll still be able to hear that the XYL wants to go to the store, the dog wants out, and you had a really good hot dog for lunch ... oh, behave! Heaven forbid, I gotta learn something new? What if a GEO presented an opportunity for multiple high-definition channels. The proposed DVB-S on a hamsat could bring us ... + A channel for every ham radio podcast and ham radio video cast we know of ... on demand, sans Comcast, or AT&T? + ARRL on line? + Licensing classes on demand? + Self learning for everything we could think of or aspire to produce? + AMSAT meetings and nets in real time? + The next time an entire island gets wiped out by a hurricane real-time delivery of the ground-truth to FEMA in HD quality? + FEMA's ICS training on-demand? + Access some of the above with your 145/440 MHz HT via terrestrial gateways? + Everything ARISS does we'd have a channel? + Good stuff on NASA TV, ariannespace.com, spacex.com ... maybe we could watch? I'm excited ... and, I'm hoping my friends will be able to fill in all the features yet to be named! -- 73 de JoAnne K9JKM k9jkm(a)amsat.org

Problem.. ISAT (Dstar One) in SatPC32's Doppler file wrong? My IC-9100 is not responding correctly to the following "ISAT,435525,437325,DV,DV,0,0,Voice,U/U" Radio shows "Off" on the 435.520Mhz UHF top freq, but shows TX 145.950Mhz DV on the lower instead of 70cm DV. Steve NS3L

VHF/UHF Beacons in EM63pf
by Les Rayburn 08 Feb '19

08 Feb '19

With the considerable assistance of Marcus Thomas, KF4YHP, we’ve finally got the N1LF/B beacons on the air from EM63pf. The beacons are CW only, and located at the Pinnacle Lookout Tower, in Shelby County, Alabama, near Birmingham. 10 Meter: 28.268.5 MHz (3 Watts) 6 Meter: 50.068 (.5 Watt) 2 Meter: 144.300 (.5 Watt) 222: 222.068 (3 Watts) 432: 432.298 (10 Watts) If you’re nearby, or operating as a rover this may help with evaluating antennas, pre-amps, etc. Hope they encourage more weak signal DXing in the South. Receptions reports are welcome. 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf AMSAT #38965, ARRL Life Member, CVHS Life Member, SVHF Member

Re: [amsat-bb] SKCCc on the satellite
by David Loftus 08 Feb '19

I’d be interested in any sort of satellite CW. I am only able to work V/u like FO-29 since I’m currently just half-duplex on linears and need to adjust for downlink Doppler by ear. K5IX Dave SKCC #3026

Vhf/Uhf amplifier for Icom Z1A?
by Bob Hammond 07 Feb '19

Any recommendation for amplifiers for my Icom Z1A? I want to use it with my antennas while I no-so-patiently wait for the IC-9700. Bob W7OTJ DN17
