I bought a D72A a little over a year ago because it had APRS built-in; this made it very handy for the balloon-chasing I used to do.
Now I'm trying to set it up for SO-50. I'm successfully putting it into full-duplex mode - with the 144 Mhz freq (pl 67.0) on the B-band, and the 435 Mhz frequency on A-band. (Duplex cannot be engaged while the radio is on the A-band.) I'm running into two problems though.
1 ) Whenever I want to change the receive (downlink) frequency because of Doppler, turning the knob changes the B-band side, the transmit, which is what I don't want. As it is, since I can't get the 435Mhz to change, this setting is only going to allow me to hear the satellite mid-pass
2) I had the idea of putting this/these VFO settings - including duplex - into memories, one memory for each 5 Khz step on receive. When I follow the manual directions for entering odd splits in memory, whenever I check to see what's in the memory by transmitting, (it appears) I'm just transmitting simplex on the 435Mhz frequency; the radio's display doesn't change (other than the s-meter showing that power is being transmitted).
I'm wondering how others are making their D72s work successfully on SO-50. Is/are there (a) certain step(s) that I'm missing in order to change the receive frequency AND enter full-duplex VFO settings into memory successfully?
Thanks for the help...either replying to the BB or to me personally is ok. ( N4HF@AMSAT.ORG)
