Just over a year ago, during an event our club provides communications
for, my Radio Shack HTX-202 ht started intermittently transmitting at low power even when set to "high". Since then it has gone to low power all the time. This happens using battery or external power with the whip or external antenna. The Google search revealed KB8ZCJ's fix for his problem but I don't want to solder unnecessarily and am not convinced that mine has the same malfunction as his did. http://www.phreak.org/radio/mods/htx202fx.txt The LCD's on mine light up as low power. And the http://www.mods.dk/view.php?ArticleId=2721 page told how to, apparently, make the radio permanantly either high or low power. Any recommendations on a switch replacement or a repair facility? Thank you for your efforts. Remove nospam for email reply. Monte B. Carroll WC4MBC Nashville, Tennessee USA |

Update. I started to try the mod below. Get the switch cover off
about half way and decided to stop for fear of permanently damaging the radio. Put it all back together. Works fine now. Full power restored. Monte B.

Full power restored. Monte B. Carroll WC4MBC Curious! A few years ago, my own HTX-202 came up with an error code that indicated that the PLL had failed to lock. I decided to open it up to take a look, and while I was at it to perform a simple mod intended to remove a birdie on 146.76. When I got it open, I took a look, chickened out and carefully put it back together again. It has worked perfectly ever since -- birdie and all. I wonder what opening and closing the case has to do with fixing the control circuitry/software in that little box. 73, CJ K0CJ |

A bad solder joint would be a good first guess. It would be common to all
those issues listed thus far. A component bumped just enough to get it to make contact. OR a mechanical connection like a ground - disturbed when unit was disassembled and reassembled. "Clair J.
