WBFM with the ICOM: IC706MK2 and G, IC-703+

by Stan, W1LE

Hello The Net: Can some one confirm that the IC-706MK2 and the 706MK2G can both handle WBFM in the 6M and 2M ham bands ? Objective is to use this rig as an RX IF with a 2.4 GHz down converter and have enough detected BW for a Multi7 TNC to decode the 2.4 GHz sats. As I recall the IC-703+ can not do any WBFM. Thanks Stan, W1LE FN41sr Cape Cod

Small Mode-UV Linear Transponder Website

by William Leijenaar

Hi AMSATs, For the interrested people, I made some website with more technical information of my small linear transponder design. It can be found at: www.leijenaarelectronics.nl 73 de PE1RAH William Leijenaar ---

Re: using a microsat as a potential high altitudeVHF reflector

by andy thomas

I still think that a large unfolded and/or (partially?) inflatable structure of reflective material structured as resonant reflectors could be an interesting passive reflector of ham frequencies if it was placed on the Moon. It would be easier than a powered active repeater. I know about moonbounce obviously and the laser system left behind by Apollo. 73 de andy G0SFJ

Stealth Satellite Station?

by Kent Frazier

I currently live in a rental house and an outside antenna is out of the question. I asked about putting up a satellite TV dish at my own expense last year and received and flat out "NO". So, my current options are as follows: 1. Going out to my car and working the FM birds with my Icom 2720H and 19" whip. 2. Working the FM birds from the back/front yard or possibly inside the house with my Icom W32A and Elk LP antenna. 3. Setting up my 2720 in the house with some sort of stealth antenna and give a try at satellite APRS. Obviously options 1 and 3 still allow for option 2. Has anyone tried any form of stealth antenna for Satellites. I am really interested in the idea of combining the satellites and aprs together. -- Kent R Frazier, K5KNT AMSAT #36765, ARRL, San Angelo Amateur Radio Club, Tom Green County - ARES Sent from San Angelo, TX, United States

Re: FT-897D - WFM

by Randy

That's exactly why I thought it would be capable of it, because its NOT in the amateur band And additionally, because the handhelds were capable of that. I have one of the handhelds,( VX6-R ) but it has aviation intermod on 137 along with some other kind of Local burst data type interference, perhaps pagers or something. Although it receives it, its Not the best receiver for it in my humble opinion; though , I wish it was. Do folks typically get prompt answers from yaesu? I think I asked them a question once before and got an answer fairly quickly .. Wasn't meaning to bash them ... Just a lil frustrated with no answer .. But thanks for checking that out Tim.. I will probably just get that hamtronics receiver and be done with it. Thanks everyone .. Your're the greatest !! Randy - N2CUA PS. QST QST KB9QHO or K9CIS , I will be on VO52, 1420UTC pass FN23 ..;-) Lol -----Original Message----- From: Tim - N3TL [mailto:[email protected]] Sent: Thursday, October 29, 2009 8:10 AM To: RSwart1(a)twcny.rr.com Subject: Re: [amsat-bb] FT-897D - WFM HI Randy, The anawer - straight from Yaesu's tech department - is no. For the record, my history of communication with Yaesu has been excellent. Please let me know off the board if you do NOT get a timely answer from them. Neither the FT-897 nor the FT-857 will operate in wide FM on the amateur bands. Neither will the FT-817ND. It's seems strange to me because their handhelds will go into Wide FM for use with the weather satellites in the 137 mHz band. I'm sorry I don't have a better answer. 73, Tim - N3TL ________________________________ From: Randy <RSwart1(a)twcny.rr.com> To: amsat-bb(a)amsat.org Sent: Wednesday, October 28, 2009 10:31:11 PM Subject: [amsat-bb] FT-897D - WFM If I have asked this question previously, I apologize. ( getting old sucks sometimes hi hi ) I would like to know if any of the radio guru's out there Know of a way to persuade my 897D to receive in WFM on 137 Mhz? The only place it does that now is on the FM Broadcast band .. I would R E A L L Y like to do this .. I emailed yaesu with the question ..

Been working CW and SSB on VO-52 simplex ..and Its going great .. Was quite the lil learning curve though. Now I just Need some a better antenna system, preamp and duplexer.

Stealth Satellite Station?

by Tim Goodrich

Build a 2m and 70cm Quadrifilar Helix- they'll give you coverage virtually horizon to horizon. Stick them on the roof by using a number of hose clamps to attach the PVC mast to one of the roof's metal plumbing vent pipes (not a gas exhaust or anything with hot air). Low profile, completely temporary, and good coverage. Tim KI6VBY

ARES 1-X 10 0n 10 launch

by Luc Leblanc

I just review my DVD recording of the ARES 1-X launch, what a spectacular launch for the tallest rocket in the world. It was amazing to see how in 3 years this rocket pass from a paper sheet to a 300 foot rocket. But it could be the first and the last launch for this amazing 450 millions rocket project. It make's me remember the numerous AMSAT-NA post AO-40 failed project. I now know why and how things evoluate from the 1960 Redstone/Atlas and Mercury project failed launches to this brilliant ARES 1-X success... a 500 Hockey mark. The human factor and knowledge! experience came last as it's often just to confirm the process of bad decisions. Will ARES 1-X survive? It can at least be a wonderful amateur radio satellite launch opportunity but for this it take's will and leadership! A very hard to find resources when ITAR is so easy to invoke...
