CHIRP

The Radioddity website offers only their V1.07 programming software for the VV-898E, even though its firmware is 1.08
Note that this software shows band A and band B channel lists separately.

So I entered 2 vhf repeater frequencies into the A list, and 2 UHF repeater frequencies into the B list.
The instruction manual emphasizes that for memory mode we must enter the offset frequency manually.
So this seems to work.!!!
However, CHIRP current build does not read the memories correctly and must not be compatible to the v1.08 radio firmware

See https://chirp.danplanet.com/issues/4069

It appears that the v1.07 Leixen program software works quite well with my VV-898E V1.08 radio, and works with windows 10 too.
Some of the earlier versions of the Leixen program software like 1.03/4 work better in win 7 or even 8.

Sorry to say that I don't recommend the use of CHIRP of any build, with this radio, because of its variations from V1.02 to present, for which Leixen has released 3 different versions of the software vs model suffixes.

The 2 separate frequency memory banks in the radio (A and B) are not or don't seem to be addressed at all in CHIRP, and none of the very important Function menu 50 odd items are either.

In my opinion, this seems to be one instance where CHIRP should remove its listed support for the VV-898.
