The volume controls on this rig are now playing up. When turning the volume down completely it sometimes goes down to VOL:01 but no further. It sometimes is apparent on VFO B but VFO A is not immune either.
I know that the control uses an optical chopper to convert rotation to pulses to tell the hardware to change value. The result of this is the sound can not be entirely muted. There is also an issue with the channel knob which again uses a chopper. Sometimes it cannot change channel properly.
The rig is permanently in the shack so not subjected to different humidity or heat. The problems are intermittent and sometimes the rig works normally.
I've had a Trio 7500 2m rig for nearly 40 years before it developed any issues. THe Wouxun has been with me for just over 3 years and upto know has been ok. I'm not going to bother getting it fixed and may well just buy a Yaesu rig instead. I never use 10m on the Wouxun and most of the time it is used on 2m or 70cm so even 6m doesn't get a look in.
If anybody knows of a fix for this I am all ears.
Hi buddy i just got the same radio, is there a way to program the last 3 digits on the frequency display as the program sets everything to a 0 or 5? Searching the net without much luck.
ReplyDeleteWondering if you managed to solve this yet? Has a factory reset been considered. I have the same problem.
ReplyDeleteGot the same issue here, VFO A volume won't go below 3 which is quite loud, especially late at night, any potential fixes appreciated.
