Hi Folks,
Is anyone using one of these on the FM Sats? If so how well does it perform? It appears to pretty much the same as the KG-UV9D but without the extra wideband receiver ranges.
It seems to be able to do full duplex.

He reviews a lot of the Chinese radios and posts his results on the QRZ.com forums. I think the consensus is they work okay without desense in V/u on the Fox birds but not in U/v with SO-50.

Hi Terry!
The KG-UV8D can work the AMSAT Fox-1 satellites with 70cm uplinks full-duplex, but not do full-duplex on SO-50 with its 2m uplink. Even though the KG-UV9D has a receiver with much more coverage than the KG-UV8D, I found that the KG-UV9D (this also includes the KG-UV9D Plus) has a better and cleaner receiver for FM satellite downlinks than any variant of the KG-UV8D. I have not tried any of the new dual-band Chinese-made FM/DMR HTs, but for the rest of the crop of dual-band HTs from China I think the KG-UV9D (any variant) is probably still the best performer for FM satellite work.
John KG4AKV already mentioned a couple of links where I wrote about the KG-UV8D on AO-85. I also wrote about it on this mailing list in late 2015 around the time AO-85's launch. My comments about these Wouxun HTs, along with two other Chinese-made HTs, appeared on this list. A summary, which has links to the messages covering each radio I tried, can be found at:

After seeing that the KG-UV9D performed better than the KG-UV8D, I sold the KG-UV8D. I still have the KG-UV9D, and periodically use it for FM satellite work.
Should you go with either Wouxun HT, be aware that the radios always have a small current draw - even when powered off. If you don't use the radio all the time, it would be advisable to either remove the battery from the back of the radio, or put a piece of paper between the battery pack and the contacts on the back of the radio. This will ensure the pack remains charged and ready to go, instead of possibly ending up with a dead battery pack at the same time you want to work a satellite pass, or use a repeater.
Good luck, and 73!
