About the only other consideration I can think of is hugen has made some
worthwhile improvements which he has included in Version 3.4 of his PCB.
Was searching for info on the v3.4 improvements and found this from hugen79 at a Gidhub message exchange where he mentions at least one of the improvements:
hugen79 commented Nov 12, 2019: Noise problems introduced by USB connection I will use the new power chip in NanoVNA-H V3.4 to improve this problem. I will try to increase the capacitance of the si5351 to reduce noise. The problem of LED flicker noise can be improved by software.
Whole thread is here:
I assume most of those improvements might mostly have to do with reduced noise on the extended or upper frequency ranges? Since I would mostly be using it for 500MHz at most and much lower frequencies, perhaps I could get by for now with an older v3.3 board. Still be nice to have the latest revision.
In any case opened an Alibb account to be able to send M.King a message to ask if they might know of any ebay seller that has the most up to date v3.4 board in stock. Lets see what they answer. Thanks.
