This is Horey, VU2HFR from Calcutta, India. I have had the FT100D for the last 10 years. My brother VU2KFR and I have repaired the radio thrice during this period. Once we replaced a faulty 2SC2714 transistor in the driver chain, once we had to replace the control card after a lightning strike and recently had to replace the MRF255 power FETs. Very recently the radio is down again.
This time the problem is a flashing frequency display. After switching on the radio after a few months the radio appeared dead. No RX or TX except a flashing frequency display on all bands. All other functions such as frequency change, mode change, DSP settings can be changed. Only the frequency display on all bands keeps on flashing and there is no audio. The S meter bars are all on and the RF gain / squelch control has no effect on the S meter display. I tried re-fixing the flat cables going to the control head as suggested in this group without success. Somewhere I have read of a similar problem due to VXO unlock. Any help / suggestions in this regard would be welcome.
