It works but has very serious images at about 3.3 and 3.6 a few hundred kc wide. Also same thing up on 20Meter band in wide spots across the band. Sounds like AM bcb bleeding through but haven't been able to match the distorted signal to anything on my am radio. When away from the noisey areas on the dial, the real signals sound fine although the rx is fairly deaf unless I REALLY peak the antenna closely with my mfj-949 tuner(longwire & hy-gain vertical). I dont know if that means anything or not but my other rx's(r-390,nc-300,HROs...) front ends seem to be more broadbanded and can literally pick up signals with a piece of wire. Also, I don't get this same interference on my other rx's using same antenna, etc, so I'm concentrating on the receiver. I recently aligned it via the orig manual and checked all tubes. PTO tracking isn't too far off. Most caps were changed by prev owner. Everything else with the receiver looks fine otherwise. I'm not sure where the "leak" is coming in via mixers or what. I'm not an expert on rx repair so I thought I'd ask some experts on the list to find out if this kind of problem usually boils down to just a few things. Any help or suggestions will be GREATLY appreciated.

Good luck. If it blows fuses with the rectifier tube removed, this is almost certainly the problem. But, the good news is that when this happens, the shorted turn is almost always on the (very fine wire) HV secondary, which is the top winding in the bundle and the easiest thing to rewind. --scott -- "C'est un Nagra.

C'est suisse, et tres, tres precis." I'd suggest removing all of the secondary windings at this point. It could be a wiring problem--such as a pilot lamp socket shorting out, or even arcing in the rectifier tube socket. You have nothing to lose. The dim bulb test on a transformer will the secondaries unloaded will reveal a shorted winding quickly. If it is the transformer, I suspect the radio should have some burnt odor to it. They usually take several minutes of cooking to fail to that degree. Next step is dumpstering/parting the receiver, or finding a donor. Those R-100s are problematic with the PCB style bandswitches...

My guess at about 200 mA is ok, I guess. The choke is pretty charred... all the varnish was boiled out and dried on the chassis. The outside paper is brittle now. The filter caps seem ok. I checked them last night and they have between 35 and 50 microamps leakage at full charge and working voltage. Today I will wire the choke back in and use a Variac to check for abnormal current draw. I'm not discounting a shorted turn or two inside the choke although the dc resistance seems normal. I did just buy a 10H, 300mA choke on Ebay with about the same form factor. The power supply filter is the classic pi with 40uf input and 80uf (!) output. That capacitance combined with 7 Hy sure doesn't seem anywhere near 120Hz for filtering. But what do I know? Thanks again.

I have no idea whether it was a legit amplifier or not, but they always use to sell that sort of amplifier as for the business band adjacent to the CB band. Not being in the US, I never looked at the US rules to know if they were legit for that purpose or not. Sonar was a big name in two-way radios. The only reason a bandswitch is needed is if the amplifier or rig covers more than one band. That sort of thing is common in amateur radio, but not in other services. Note even within amateur radio, people would build single band amplifiers (sometimes low power, sometimes full kilowatt), and a good example of commercially built amplifiers are all those amplfiers for the VHF and UHF bands.

The model numbers are all starting to run together in the ole noggin (hey I'm getting old!) and it's been like 5 years since I had this thing. Anyway, it was one of the big dinosaurs. The scope worked fine but I had no room for it, so I stripped it. May have some other parts floating around too. The transformer does have a part number I can supply. If anyone is interested, let me know. "I" don't need it. Not sure what shipping would be, this sucker is heavy.

Both functional. I gave up on finding the matching receiver, and am off into other things. Anyway, KW Electronics used the same supply for all the radios. You need some spare parts? I've got 50 bucks into the whole thing. Jim WA9Z John L. Sielke wrote: > Does anyone know where I can purchase a power connector for a KW > Electronics KW-2000B? I need the female plug.
