Ham Radio Circuits and Repair / HTX-100 repair
« on: February 06, 2020, 01:22:38 PM »
I have an HTX-100 that needs some repair and I need some guidance... my only repair experience is on things that use tubes and weigh 50 lbs... if it has ICs, I simply have become an appliance user.
I was forced to take down my station 10-12 years ago - - this radio has been in storage in my house since then with no temperature extremes. I am the original owner and it was working when I put it into its box. I am now setting everything back up. When I apply power, the display light lights but there is no information... no frequency, no nuthin'. There is audio, but there is no static sound when I connect the antenna.
My first thought is: bad capacitor. I pulled off the cover and looked at both sides of the main boards with a flashlight and magnifier... none of the capacitors had an indication of having split or burned, and there was no trace of leakage on the solder side of the boards. I do not have a full schematic or a shop manual, so I don't know where to turn next.
I watched Buddy's repair YouTube where he brought back to life an HTX-100 and checked what he did in that radio, but I do not think I have that problem...
