Description

Using latest daily CHIRP (end of Apr 2019 ver). Radio is a brand new variant that it is similar to the MTC radio UV-5R-3, or the Radioddity UV-5RX3, or the BTech tri-band, basically all are VHF/220/UHF tri-band dual-power variant of the UV-5R radio. I own the MTC variant and successfully use CHIRP in programming everything including 220, no problem.

But with this new model, bought on eBay recently, it works with VFO, manual programming 220 to memory, but CHIRP throws out the out of range error, obviously not understanding that this new model can do it, despite the other settings clearly shows that it can go up to 260 on VHF range (unlike MTC, this page shows only 2 freq ranges.).

So any editing will pop up this error message, entering a memory label name will not work because of the error (even I have successfully entered the memory via manual programming already, and read back the image to CHIRP. Factory entered 220 frequencies also have same problem).

The firmware version is HN5RV01, and I traced that to one of the dual band 5R, obviously they didn't use a unique firmware version identifier to distinguish it.

I have already notified the seller in Asia about this.

I have also attempted Baofeng CPS and tried 2 versions dated 2016 (nothing newer I can find) and none would let me enter 220 frequencies as well.

The radios look new, and the 220 does not seem to create huge harmonics (I haven't put it on a bench test on that yet). So it seems that hardware wise it isn't too big of a diff to at least the MTC one, if not the other 2 variants from Radioddity and BTech (BTech might have unique features.).

I think it shouldn't be too hard of a fix, as I noticed that old hacks have been avail to enhance the non compliant dual band versions years ago, so the theory should be similar enough. I tried to get the .pyc file to replace the one in the library as well, but read that the method used is deprecated.

This is a very good deal for a tri-band radio. I think this is the last step that it must work or it'll be very painful. MTC no longer sells theirs, and Radioddity and BTech ones are a bit higher in price.

I hope someone would release a fix for this sometime.

thank you to everyone involved.
