Guess I'll have to get used to it the digital readout from http://www.electronicspecialtyproducts.com/dd103.html looks pretty good?? any feedback on that unit?
Thanks
George

I have a Kenwood 520 are there other remote VFO that are compatible with the 520? my goal would be to have one that would require more turning between kilocycles. Making it easier to dial in stations. I  used a icom 7000 on field day and it required almost 1 turn to move 1 KC
Thanks

Found the arcing on the band-switch, destroyed the wiper on the switch, I am trying to find a replacement. The radio works fine on the higher frequencies (that part of the switch is ok) Radio tunes up to 100 watts no problem
Thanks
George

The band-switch on the 520 is different than the 520s or 820, Didn't look to hard to change, just mark the wires and make sure it's in the right position.
On my rig the wiper that contacts the pad was completely burned off, Silver ink wouldn't work
George

Found the band-switch at www.hifissb.com did not have it listed so I left a email and they responded the next morning that they did have it. Only downside it's coming from Great Brittan
Thanks
George

The Lesson learned was think it out before plugin it in!!
and you are right the power output transistors did bite the dust
George

Wasn't using my head, tried it, smoked it..... input power to high  
Trying to figure what i blew up no visible damage just smoke
Really ticked myself off

Found burnt resistor, Might get lucky.... Lesson learned

Has any one heard of a CMI Power Master 100 amp? I don't have any specs on the unit. The label says 160 watts AM, 300 watts SSB there is no reference to frequencies. I assume it would work on 10 11,and 12 meters???  but what do you think about lower frequencies??
Thanks
George

I am looking for a band-switch for a Kenwood TS520 the part number is S10-1101-05 any suggestion would be greatly appreciated
George

all depend which band I am on on 80 meters it's empty 3.5mh plus 300kh is 3.8mh were the usable frequency begins. 40 meters not so bad 7.0mh plus 300Kh is full

Thanks for the video link, Tuned it up with the instructions from this sitehttp://www.k4eaa.com/tune-up.htm on 20 meters (100 watts everything fine) into a dummy load.
I later tried to tune up 40 meters and i started getting arcing?
Guess Ill have to pull her apart and see if I can see what is happening
any help will be appreciated
Oh and yes I have the manual and I even read it a couple of times
Thanks
Again
George

I bought a Kenwood ts530 I am new to using tube type radios, according to the user manual i must dip the plate current, but The plate current does not seem to adjust anything it is very low, but still no adjustment??

Later last night I over drove the radio and it started arcing, any thoughts on what it might be??

Belive it or not I am Having FUN

Thanks
George

Thanks everyone I got it working, someone had used grease at the ground wiper connection. Some fine sandpaper and contact cleaner and it is working perfectly

George

Thanks for the reply's
I pulled the vfo out and cleaned the ground connection were it brushes the rotor and that helped but it is still not right, I could use some more information on installing that wire.
Does the wire just go around the shaft and apply more pressure on the rotor or did you physically solder a wire to the rotor and the case??
Thanks for all the help
George

I just bought a Kenwood 520 it works! the only real problem i see is the radio goes silent when the VFO is tuned to approximately 300. Does not matter what band at 300 it quits. Is this a comman problem with these old rigs or did I just buy a real boat anchor
Any insight would be appreciated
George
