The Connex 4300hp is the last of a dying breed of 10 meter radio that still uses 2SC2290 transistors and not the mosfets that a lot of the more recent 'power' radios posses. Get one while they are still in stock because there is no guarantee these will be available indefinitely! Troubleshooting no transmit complaint in a export radio. Duration: 9:23.

I have a connex 330HP that I want to put a powerband rfx-75 on but this radio is not stock it was given to me this way. I want to put it back stock so I dont have any problems with the new kit. Can anyone tell me a part replacement for TR32. There is also a diode with a resister on the solder side of the board to the upper left corner it does not look stock to the soldering looks like crap. any one have any ideas? I also noticed that there is a sticker on the inside of the radio that says 3300 HP-ZX does this mean anything important? There is also a relay glued to the board that that activates upon transmit is this some sort of secondary talkback because I noticed that the stock talkback appears to be disabled. It also has 2312 finals in it. With this information does anyone know of any more parts that might have been changed. I guess I am asking for a check list that could get radio back stock. Any information would be appreciated.I collected this radio to try to repair for a friend, now I seem to have inherited it. It shows good carrier, about 40 watts which i plan to lower. good receive and is on frequency both send and receive, but the modulation just slightly bumps the meter and drops back. no sound output when you key up. Just dead key.
I have tinkered on radios awhile, no expert, but I can solder and test a few things on my multimeter.
