Does anyone know of a website that is like the Fox Tango Yaesu site, but for Kenwood radios?

hi Richard,

which Kenwood are you interested in?

K4EAA has a nice website  http://www.k4eaa.com/

and there is the yahoo forum that has over 2,500 members

http://groups.yahoo.com/group/TS-520_820_530_830/

join other ts-5xx and 8xx fans at the above group.

Thanks for the info Jim. Im already a member of that group and K4EAA is going to refurbish my minty TS-520S when I find the extra money. Im looking for a website that gives more details about these radios and what accessories were available. I was hoping to find a nice site like the Fox Tango site, but so far, the K4EAA site is the closest that I have found.

Not to sound silly, but you might try the Kenwood site itself.

http://www.kenwoodusa.com/Communications/Amateur_Radio/

Click on support, go to the amateur radio section, and you can get the manuals, service notices, brochures, etc. for most of their products.

Have fun!

The definition of mint is "as new, right out of the box". What's to refurbish?

Of course to some people, "mint" means it's not a rat-infested mess. Smiley

Well, the radio IS very clean, almost perfect. But it is also 32 years old and probably could use some new caps, resistors and a good alignment. I want it to perform as good as it looks LOL

hi Richard,

this is courtesy of Mike, W5RKL on the ts-520 yahoo forum.

really no need to replace anything else unless they are out of spec.

73 james

The important capacitors are the HV capacitors (directly behind the VFO), the bias supply capacitors (2 x 33ufd 160VDC on the Rectifier Unit), and 2 x 2200ufd 16VDC capacitors on the bottom right corner (520 turned upside down).

If you replace the 2 x 2200ufd 16VDC capacitors, replace them with capacitors that have a higher voltage rating, 25VDC instead of 16VDC. Maintain the same capacitance, 2200ufd and same axial lead capacitors. Kenwood increased the voltage rating of these capacitors in the 820, 530, and 830 series hybrids.

There are 2 black dual capacitor cans located under the VOX and Marker UNIT boards. Each can has two 22ufd 450VDC capacitors inside each can. These require some work to get them replaced. There are no original direct replacements for these caps. These are the filter capacitors for the 300 and both 210 Rectifier Unit supply voltages. To find them you must remove the VOX UNIT and Marker boards, 520 right side up front panel facing you, on the top left rear. The wiring is on the bottom.
