I think the V2 is an improvement over the V1, at least the way that I use it. My v1 was doing about 60w peak and drove my 4 pill X-Force nicely. I suppose that if I had an 8 pill, then 100w peak drive would be nice to be able to do.
On the V2, the noise reduction feature works well, although it is not adjustable like on the K-PO DX5000+. The selectable tx and Rx bandwidth does what is intended, listening to a monitor radio with headphones will help discern. The electret mic selection is great, I run a Uniden BC465 mic and it sounds fantastic. It compliments the 4k transmit selection nicely. The noise gate feature is nice to have, especially if your amp has a fan on it. The coarse clarifier now changes the 6th digit on the frequency display, instead of just staying 0 on the V1. The fine clarifier shows on the main display.
The 10 meter guys will appreciate the V2 with the built in CTCSS feature.
If you already have a V1, then maybe the new features might not justify buying a V2. I am going to hang on to my V1 for now just in case.
