External Radio Transmit Track Rx ?

#1

Unread post by Hasan_N0AN »

SDRC is nearly the PERFECT program for working satellites. The only place it is lacking is when running an external radio, there is no provision for having the External Radio Transmitter and the Internal Radio Dongle Rx track when running satellites.

I have no idea how hard this would be, but if possible, I would love to see it added to SDRC.

What I"m looking for is if I have a standard pair of frequencies set so that I'm listening on 145.915 and transmitting on 435.290, AND my voice is in perfect tune ...

Should I need to move up to 145.925 to catch someone, ...when I do that, I would like the transmit VFO to properly track as I move the rx dial. In other words, the transmitter should move the tx vfo DOWN 10 KHz when I move the Rx VFO up 10 KHz to catch another qso. (obviously not all birds are reverse, but all the Mode B ones are).

It would be nice if we could enter a "constant" for each satellite in the SatList > Current > Organize section, that reflects and would keep the Tracking of VFOs up and down in the right place as we move the receiver VFO.

Can this be done?
Is it difficult?
Simon, would you consider doing it?

What I do now is use math. If I''m already tuned in to my signal and I want to move, I note the rx freq, click where I want to go, then if I went up 10 on Rx, I tune down 10 on Tx and all is well. I can live with it.

But...auto-tracking would be soooo much nicer.

Hi Hasan

I thought you'd posted twice in error, so removed the other topic.

What I have done is moved the topic to External Radio but left a marker in place in the Satellites forum, so this same post together with any replies will effectively appear in both sub forums.

Cheers
Jim.

Thanks, much appreciated. I'm not used to the new system yet.

Need help trying to work satellite's with FT857 and Ham Radio Deluex. Running Sat Program on HRD for TX only. Trying to run SDR Console in Sat mode for RX only same will not track the RX Downlink freq is there something wrong with the program???? Have MFJ 1708B RF Sense to prevent FT 857 from TX on the SDRPLAY. Please email hhallcosd@yahoo.com or call me at 505-290-7599 thanks K5HLH 73s
