I have used my Kenwood TH-F6A along with an Arrow antenna, and IMHO it works 
just fine. You do need to get it programmed right and you need to get used 
to switching between VFOs as you track the satellite and the Doppler effect 
on frequency. It is NOT a full duplex radio like the W32A, and you will not 
be able to hear yourself, but I have never felt that's been a problem.. I 
programmed mine to transmit on one VFO (uplink) and be able to receive on 
several different frequencies (downlink) on the other VFO. On the transmit 
VFO, the squelch is closed all the way, while on the receive VFO, it's open 
all the way. So, VFO A is set for uplink of 145.920 on memory channel 150 
and on memory channels 152-153 I have them programmed for 435.290 and 
435.295 (downlink which is in VFO B). 154 is center frequency of 435.300 and 
of course 155 and 156 are set to 435.305 and 435.310. By switching between 
VFOs I can change downlink channels/frequencies to fit the Doppler shift. A 
little cumbersome, but that little radio works very well. You can follow a 
similar scheme on the QRP channel of AO51 (mine is 160-166) and SO50 (mine 
is 170-176-get the picture). I have made several contacts with it on the QRP 
channels but have had no luck on SO50, which is a lot more difficult 
satellite to hear.
 I'm using it because it's what I had, and I'm happy to say with a little 
use and practice you quickly get the hang of it.
 Of course, either the W32A or the Kenwood TH-D7A do FULL duplex, but both 
are no longer in production. Hearing yourself is nice, but not necessary.
