... "what is the best current handheld for FM sats"??
We do not have a currently-manufactured TRUE DUPLEX HT available. Alinco tried - but the sub-band receive performance on their DJ-G7T is gruesome.
I use and like the Yaesu FT-60R - for MANY reasons ...
-Receives 108 to a gig -bulletproof case -strongest belt clip of any amateur HT chassis on the market -easy to manually program -1,000+ memories -large, easy-to-read display -and a battery situation that is great. Load up the optional FBA-25 AA alkaline tray with alkalines or NiMH cells, and you have FULL TX POWER available, is needed. Do that on, say, a Kenwood TH-F6a, and you have ONE-HALF WATT TX power.
Oh - and the Yaesu FT-60R can be programmed for "split freq" ops - where is receives on 440 and transmits on 2M.
Overall, it is a tremendous value for your money. Under $200 at HRO and AES and other authorized Yaesu dealers.

Have you tried the latest firmware? They have adjusted the filters and the RX on UHF on main/sub-band is much better. You can also download the service manual and change these parameters yourselves but this is probably not something that should be done.
Comparing it to my TH-D7 it's not that bad. They changed something on the 23cm too but i'm not sure what the issue was there.

What version firmware are you at, Kai?
I will need to re-evaluate this unit!
E5.000
[Updates of this firmware version] 1: RIT/TXIT functions / added. 2: Reverse function in repeater operation / bettered. 3: Beep sounds at turn-off the power / added. 4: CTCSS tone of Auto-repeater & memory / bettered (give priority to the tone in memory, not in VFO while auto-repeater is ON) 5: Welcome-screen setting / bettered. 6: New scan mode added = turns on the LCD light when scan stops. Very convenient operating G7 in the dark. 7: Firmware update operation: accepts the command only when the battery-icon shows "full". 8: Minor bugs fixed.
Previous firmware: Bettered receiver performance around 320MHz range.
I have not tested this on the birds. But the local repeater using the same antenna. Not a very advanced test. Receiving the repeater before upgrade, flashing the firmware and test again from the same spot.
Anyhow the original antenna is not good on VHF but i think the UHF/SHF is better. Using the original antenna for the TH-D7 on the radio you gain better signal on the Alinco. So i have replaced the antenna for a SC951 SureCom for V/U and SHF and now it's better on VHF too.
On the birds i probably want to use another antenna but the SC951 should work ok and better than the original on V/UHF. For SHF i have nothing to compare them on.
I really like the dual-memorybank(splitband) so they are perfect for the birds. But i have not done any QSOs on the birds using this radio. But with the dual VFO control it's probably bnetter than the TH-D7 as you can adjust for dopler on RX on the Alinco. (The TH-D7 can only adjust the band you are TXing on)
So then i just have to try AO51 ;o) i just wanted to say that they have done something with the filters and i think they have adjusted more than just the 320MHz range even if they don't say so.
They are responding relatively fast on e-mail if you have any questions or suggestions for new functions or to change something into the better.

Kai - Are you working with Alinco in the U.S.? Is yours an Alinco DG-G7E or DJ-G7T?

Hi Guys,
I just ordered the microphone/headphone cable from HRO for my DJ-7G so I will soon be able to try it out on full duplex. I am very pleased, by the way, on how well the sub band receiver hears the satelites.

No full duplex handheld - here is a simple solution.
Use two rigs. Buy a 5w 2m radio for the uplink. Several good ones available available at low cost. If using an Arrow run separate cables for each radio, this avoids the diplexer which some on this list report as a source of extras loss.
Works fine for me
