I have a Grant I bought along with it that is still working fine as well as a Cobra 2000 GTL bought a year later. They have both have stood time. The Washington lost its ability to key and I let it sit in the corner. I believe it is the keying circuit and I seem to recall the fix for that so...

Can someone recommend a repair person for these radios? I am in the Bay Area of San Francisco if anyone is local. I can ship it if required. It needs a tune up. Been sitting in storage and it doesn't key up. Everything else is fine it appears. Thanks for any recommendation...

Has anyone whose owned an EICO 715 Transmatch confirm if the RF and Modulation functions work with the internal dummy load disengaged? All functions work with the dummy load engaged except these two functions when the dummy load is disengaged. The meter has been completely gone through and I...

Thanks for this. Very nice setup indeed. (I just realized you stated this in your earlier post. I had to re-read it again. Sorry about that. I was happy to see someone else using BBE).

Same here. I have it just before my tubed compressor/limiter which precedes the mic input. I was curious as to other's experiences with it. Good piece of gear in my experience. I originally used it (and still do) in my recording chain.

I use BBE processing. It was designed for commercial radio use and it really works quite well if you don't overuse it. Where do you have it in the audio chain? Does the chain as pictured represent the signal flow from preamp down?

Ah, excellent, thanks. I indeed meant the former; that is, using an antenna tuner (sorry, I didn't make that clear). I always thought lower inductance was better, although admittedly I did not understand the broader bandwidth aspect, and capacitance tuning would then follow the lowest...

Is it more ideal to have a higher capacitance on the transmitter side than on the antenna side 'in principal' when tuning an antenna? Secondly, is it better to have a higher or lower inductance? I understand the obvious answer: "whatever achieves the best SWR with the best forward"; however...

Thanks, guys, I hope others benefit from this. To add a bit more to the pot, I have found that using a balun between radio and amp as well as just after the meter, blocks RF on the shield so the radio is happy and the meter reads correctly. I got this from Dr. Selvig's writing. It is most...

Further for those interested: Had a colleague whose SWR light on his base radio came on whenever he turned on his amp. We checked the SWR directly connected to the radio and found it flat with the amp off and 2.0 with the amp on. Ordered a 100 watt LPF, tuned it to precisely 50 ohms/.05...

Thanks for that. The ICE is a 9th degree filter. There is no description for the YA-1. The difference is in the coil layout. The ICE has two additional smaller coils along with the three main coils, which are common to both, and they are much heftier. It is very robust inside. The YA-1...

I noticed something interesting when checking two LPFs, a Bencher YA-1 and an ICE 421. I connected them both directly to the load side of my LP-100a into a dummy load and noted the ohmic, reactance and SWR readings. I tweaked them both to the same reading. They both measured identically the...

Thank you for the reply, that was my assumption as well, and I appreciate your input. It certainly appears robust enough to handle a constant carrier of 750 watts with PEP of 2.5K and a SWR of 1.5 or less. I am thinking it should be fine. I have two of them: one used as a radio switch and...

Would you know if the Alpha Delta-4 can handle 2500 PEP or someone who is running that amount? I can't find anything to say it does but I suspect it should. It seems quite well-built and the military but I'd be curious if you have any input here. Many thanks...

I have one I bought new 26 years ago which is peaked with a modification done to the microphone circuit to open the audio frequency and here is what I see on a LP-100a into a dummy load: 4 watts dead key with 12 watts PEP. SSB is 12 watts. I have a second one I got for parts which keys the...

Thanks! I appreciate this. I looked on CBTricks and saw your post but not the mic. I'm going to clean this rascal up and put it into service.

I have a Turner SSK I acquired dead. I have it pretty much done but the battery leads were disconnected and I can't seem to find a link to a site with the schematic. Would someone point me to a link (or tell me where they go) so I can solder the battery leads back into the mic. Many thanks..

When we swept the Bencher with the spectrum analyzer last year, it was limiting the signal above 25mhz and reducing the power output so I shelved the filter. After the adjustments, the roll off didn't start until after 30mhz as designed and the insertion loss was negligible. With the SWR...

I used a MFJ Antenna Analyzer and a dummy load to check the Bencher. I first measured the ICE filter to get a baseline. I then measured the Bencher and it was significantly off. The SWR was just under 1.9 and the impedance was substantially off as well. I then adjusted the filter to match...

The technician's name at Clyde's Corner is Bill. He has been at this for many years and my colleagues and I have always found him honest in his dealings.
