Full Duplex as a Single Channel on a HT
Do any of the current or classic "satellite" HT's (FT-51R, IC-W32A, etc) allow you to create a single channel with a FM bird rx/tx pair in full duplex?
I.e. I turn one knob and get 435.310 145.875 {click} 435.300 145.880 {click} 435.290 145.885
I could do this with the 20 DUP channels on the Ft-100D.
Even though the IC-W32A has two "knobs", it looks like (from the manual) only one can be in memory mode at one time, so TX would be in VFO mode, and the other would be in channel mode. Is this correct?
So for each change (AOS, MID, LOS), I have to turn both knobs one click, correct? Even if I can have memories on both sides, I still have to turn both knobs -- If so, why wouldn't I just use a VX-170/VX-177 pair of HT's, and turn both knobs?
I can program my DJ-V5 to have the "odd split" (TX144/RX432) single knob channels, but of course, it is not full duplex.

IIRC, the IC-32A/AT/E does, but it's been a long long time since I used one in that manner...

I can't comment on the various HT's but I would think that you'd want the TX freq in memory and the RX freq on vfo. That's how I use my TH-F6A (not a full duplex HT).

Bill,
The Alinco DJ-G7 is full duplex and has 100 cross band memory channels that can do Satellites. You can setup 5 memory channel pairs to cover first approach, near approach, Closest position, near departure, far departure. Then just click through the memories as the satellite passes. Another DJ-G7 feature is it can also do 1 watt on 1.2GHZ uplink to AO51.
I suggest using 5khz steps on 435mhz so it does 5 memory sets.
Good luck, Don - kd6ire -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bill W1PA Sent: Friday, April 08, 2011 12:10 PM To: [email protected] Subject: [amsat-bb] Full Duplex as a Single Channel on a HT

The Alinco DJ-G5 will do so. I think that the Yaesu FT-470 did too, but it's been so long since I owned that radio that I can't say for certain.
