KENWOOD TS-440 DREADED DOTS PART-3 

Yes sir it sure is. Going to be interesting to find out what is causing this voltage issue.

@@Radionut63 the fact that it's unstable is strange.

very strange indeed!

I found a ts-440, buried under junk and dust, it had been sitting for 10+ years at the club and noone knew who owned it. So i took it home and tried it. No cigar, i got the dots, so i searched online for a while and found tons of info. After removing the potting stuff and breaking and replacing one of the switching diodes i have a somewhat working 440. 24m still has dots and 10m vfo is wobbly/oscillating. Other than that it works great, have around 1000 qso's on it 😎 12 and 10m are not so active now anyways, but i do want to fix it.

Feliz por ajudar!

I am starting to think the same thing. Perhaps even a electrolytic cap gone bad. hmmmm

Radionut63 I wonder if it would be that simple. But I guess you’ll show us.

Another video uploading tonight, stay tuned! ;-)

All that glue has been removed before when i first had this TS440

plastic trimmers maybe?

Stop looking at it then... LOL
