Halo saya memiliki masalah di bagian layar jika di lihat dari depan ada angka yang tidak terlihat, jika di lihat dari atas samping angka yang hilang terlihat semua
Hi, I have a 780, bought cheap from flea market. Totally dead, but now 145Mhz receive is ok. Totally replaced the optical rotary encoder with non optic and 7414 schmitt trigger. Still receive very weak in 430 MHz. After tuned HET, the RF unit is suspicious bad in MOSFETs amplifier. Any suggestion?
I have a LS-202. FM and USB works fine. LSB does not work on rx and tx. Any guess as to how to make a DIY fix for the custom IC's (IC403 and IC 402)? KG6YDB / VE7CQA
checked the IF lo leakage, USB 10.6969MHz but nothing when switched to LSB. I think it should be about 10.694MHz on LSB. DO you have any hints as to what I should check ? Would IC 403 be suspect ? or D411 ? Peter
