This had bad finals, so no tx and the backup batt was low so replaced it and new finals now the Tx is ok but noticed a sql problem.
Thought it may be data corruption so I got a Yaesu USB cableset to do the FW upgrades to make them up to date. Turns out there are (3) firmwares to update, all with their own special procedure:
1) Main
2) Panel
3) DSP
Since there is no DSP chip installed on the main, that FW is not there to change, that took me some head scratching to figure out with some help from Yaesu.
I can now hit a repeater with the proper PL but the sql problem is still there.
In order to hear a noise floor, you have to set sql to zero, then press txpwr button and changing power levels makes you hear the noise floor. You can set sql to 1-8 and not hear noise which seems to indicate it works. If you key the repeater after setting sql, you will hear it respond back so you are left to believe its working, but when you go back several minutes later you can hit the repeater but never hear it respond. The txpwr button has to be hit again and that process repeated but there is some sort of timeout happening perhaps involving the Dx button which alows you to be able to be active in digital, FM and maybe another mode at the same time.
When I hit the Dx button, it dont seem to respond like the manual says it should, and I hear the ant relay click once which I am not sure is normal. Complex radio and it uses an SD card behind the detachable front panel for "cloning" other radios. If I remove the card, no difference so it dont seem to be altering a default setting from the reading of the card, tho on powerup is says "Reading SD" briefly.
There is another feature in the menu called : "extended sql" and at one point I thought when I turned that off (by default it is on) the problem was gone but if you check for the problem within a certain time of pressing the txpwr button it always seems to work for a while, then something seems to be alteringthe rx mode I cant figure out....any help appreciated.
