David, not sure if you are interested in this or not, but I used a Yaesu FT-50R for 2M uplink and a cheap radioshack scanner for downlink for almost a year. While quite cumbersome, it worked great and I have many QSO cards that say so. I actually find it easier to use then the full duplex radio, and this is why. My TH-D7 requires that I "switch vfo's" before I can adjust for doppler, so sometimes I forgot to switch back to the 2M vfo and ended up transmitting on 440 instead of the 2M uplink. The scanner was easy - I just pushed either the up or down button to adjust for doppler. See the link below for more details including pictures of my portable satellite setup.

David,
You can use it, but you will not know if your signal is actually getting through the bird or if you are transmitting over someone else. I would say give it a try until you can get a cheap 2nd radio that can serve as either the transmitter or the receiver. This way you will create a full-duplex setup - with 2 radios. Also keep in mind that you will need a diplexer for the Arrow if you are using just one radio.

I would appreciate a bit of advice concerning h/t's?
I spoke with Icom US who admitted that despite the current adverts
claiming the IC-91A/D is the replacement to the W32A, its not - no full duplex for a start!
So, I have the E or T90 which on the back of a bit of research I now
find that by selecting "split" in the menu options, I can listen on 440 and transmit on 144 - its not full duplex I know, but for the FM birds (and coupled with an arrow type antenna), can I make this radio work on the birds?
Thanks in advance
