Purchased a V3 from a ham on QTH. Told it was 2 weeks old and it’s of course built and tweaked at the factory.
S/N 0994 so someone could ascertain it’s true build date.
It has several issues but the most glaring one is internal receiver noise.
Read all the forums, blogs, etc.
5v Buck boost module has a systemic problem. As some users units exhibit the exact issue I’m observing. I’m guessing some V3’s work or there would be more of a footprint here on this issue.
Tried adding of the suggested caps on the enable line also on the input and outputs of the 5v bb module. Slight if any improvements. Still unusable on 40 meters. Its absolutely worst there.
Purchased the suggested Drok module. Still problematic. Used RC low pass on the output. Some improvement but come on.
Im spending too much time on the hardware as I purchased this to help my Linux bone.
No issues updating the V3 or Pi configuration. Some struggle with the time zones correctly being displayed. No problem as having Linux experience helped.
Is there anyone who has a handle on this internal noise problem??
Dont need “what worked for me” comments.
Whats the solution?
Should be relatively easy for the folks who designed this to weigh in and implement a hard fix.?
Not complaining just need pertinent help.
Many other issues with this radio that more than likely can be fixed via the code.
AGC after unkey hangs to long except when AGC is off. Easy fix.
No S meter. Should be able to implement that via code.?
Of course the screen resizing for WJST etc.
Just to mention the obvious.
Anyway if your going to buy one of these and aren’t ready to deal with these problems?
stay away until it’s more mature. Both hardware and software.
Im just trying to get it function hardware wise before starting any major code experiments.
