Now that we have FDX (Thank you Flex!), I have been
pondering the configuration of a full duplex satellite station based around the
I currently use an Icom IC-910H on 144 and 432MHz. Sometimes I need to transmit on 144 and listen on 432 (SO-50 and FO-29 for example) and sometimes the opposite (AO-7 for example). On the IC-910H, this switching is accomplished with one button press.
With the 6700, for 144Mhz, I now use a DownEastMicrowave LDPA attached to the XVTR port. I want to purchase a 432MHz transverter (available in several I/O configurations from DEMI) but have not been able to come up with a wiring configuration that allows me to transmit on both 144 and 432 (and listen on the opposite) without some form of external switching (basically, swapping the XVTR port with one of the RX ports).
Does anyone know a topology that accomplishes this with the 6700?
I will leave the software topics of VFO tracking, etc, for another conversation.
