Good to see the experimentation, however for this to work correctly with an antenna like that one you have chosen, *you MUST use a coaxial coax feed from the PCB to the antenna socket that, is also grounded!* . Without this, the entire point from where you soldered the wire, right to the tip of the antenna becomes the antenna, and the Nagoya antenna has no ground reference. It will also therefore be non-resonant where you want it because it will be far too long!... So to summarize, if you add coax between the PCB and the antenna base, and ensure that the coax is correctly grounding the antenna base, it will work MUCH better than it did for you. (The fact it was receiving signals before you connected the antenna is proof of this not working correctly!) Good luck!
NEAT! Looks like there's about 15 inches of wire in that coil antenna. One could stretch it out straight through a small hole in the top plastic and run it through some... shrink wrap maybe or thin tubing glued in place and have a "15 inch whip antenna" without a soldering job...
I have a Baofeng T1 radio, I restored it from the factory. my problem is to reset and when I use the softweare and the usb cable I give it either on the screen control + R or control + W it shows me 00 666.666 I do it with the up and down arrow and it does not show me the 16 or 19 or 20 frequencies it should have. What am I doing wrong or what am I missing?
Beside "I do it because I can", what's the point of this mod? The T1's whole point is its pocket friendly size. And its sensitivity stays awful... And please note that it received better without antenna, and that says it all.
