KX-3 and satellites
Locked

Just wanted to claim the first use of the KX-3 on satellite, both FO29 and
AO7. Worked fine, excellent audio reports. Did need both a receive preamp and a little help on transmit as well. -- Mike Herr WA6ARA DM-15dp Home of The QRP Ranch No trees were killed in the sending of this message, however, a large number of electrons were terribly inconvenienced. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Congratulations, Mike. I'd be interested in hearing about your complete equipment lineup.

Had a few questions about the set up I am using with the KX3 and satellite
operation. So far I have been on both FO29 and AO7. FO29 is fairly easy bird to get through, AO7 can be difficult. I have not tried SO50 yet. I use the compute to control the az / el rotors but not the doppler shift. I adjust for doppler manually, using the tried and true rule of only adjusting the higher of the uplink / downlink frequencies. This works well enough for the past 30 years of satellite operation, as the QSOs are short and the satellites are (unfortunately) largely empty. On FO29, if the pass is very high elevation, say above 60degrees, I can get into it barefoot with the 3 watts from the KX3, but don't expect to do that near the horizon. Generally speaking I use 10 watts or less for most of the pass. On AO7, an external preamp is needed, especially with the only 3 elements yagi. Again, on a high elevation I can hear fine without an external preamp, but it is definitely helpful.

Also my congrats!
I intend to use my KX3-2M and K3 + 432 transverter* for crossband duplex satellite operation. Typically current satellites uplink on 2m and downlink on 435, so I have added a RFC 2-23 linear amp which can provide output up to 30w on 2m to a 7-element yagi which is way more than required for satellite operation. A low-noise preamp is used on 435-MHz with a CP x-yagi. MY az-el satellite rotator requires repair of the control box so not QRV for the satellites at present. The KX3-2M appears to work well on area repeaters and good on a short SSB test. *L432-28 transverter with synthesized PLL by DEMI; has two frequency ranges: 432-434/435-437 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: [hidden email] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
