I lifted the top cover on my CII and eyeballed the meter area (always do the easy stuff first). There's a small pc board mounted on the back of the meter switch to make it easy to plug wiring pairs i

There are no TR relay contacts in the Corsair... Its diode switched. The intermittent receive often comes from the separate receive antenna switch on the back panel. Work in a half drop of DeoxIt to
Pardon me, but are you sure? When I key mine, I sure hear something clacking. Then while in cw tx mode if I listen carefully I hear the soft ticking of something that sounds like a reed relay. thanks
Rob, I'll be very anxious to know how your PTO lube job works out. I'd like a process that would allow me to avoid a disassembly and rebuild.... just flush out the old stuff and spray in the new woul

Its really hard to clean grease off the thread through the pistol with the PTO shaft assembled. 73, Jerry, K0CQ -- Entire content copyright Dr. Gerald N. Johnson, electrical engineer. Reproduction by

I think that relay you hear is the amplifier keying relay. Some object to it's sound and stuff a bit of paper match stick under the armature to stop it from clicking. 73, Jerry, K0CQ -- Entire conten
Yes there is another SPDT "T/R" relay for controlling external devices. Its 3 pins are available on the Molex accessory jack. I'm sure that is the relay that you are hearing. Duane N9DG _____________
Oh, okay thanks--cleaning a manual switch should be easier than cleaning a relay. Rob K5UJ From: "Dr. Gerald N. Johnson, electrical engineer" <geraldj@isunet.net> Reply-To: geraldj@isunet.net To: ten
A friend of mine sprayed the PTO in his OMNI C with WD40. I worked great for awhile and then quit altogether. When he brought it to me I took it apart and found it was full of fuzzy green stuff that
There is also a reed relay that switches the antenna input to the receiver. If you have the amplifier switching relay active, you don't hear the reed relay, but with the amp relay disabled, you will
WD40 DOES react with brass, in varying degrees, depending on the alloy. Of greater concern, if I am to read this that someone has used the WD40 in an attempt to flush an assembled PTO, is that the so
There are folks out there that rub WD40 on their bodies for arthritis. It did attack the plastic. The PTO by the way (which was replaced with a used spare) ended up in my junk box. I have used parts
... this reed-relay does not switch the antenna to the receiver, it only disconnects the rf final from the antenna during receive. A pair of cheap rectifier diodes type 1N4007, which indeed have the
There are folks out there that rub WD40 on their bodies for arthritis. Everybody who has seen the film My Big Fat Greek Wedding will know that Windex is the preferred cure. -- Ron VE3SP
Of course, WD40 is not a water thin Solvent... it is a water displacer. When I referred to the solvent I had in mind products made specifically to be compatible with plastic, and to dissolve grease.
Axle Grease is the word ! :) There are folks out there that rub WD40 on their bodies for arthritis. Everybody who has seen the film My Big Fat Greek Wedding will know that Windex is the preferred cur

Not according to my schematic. The relay is in the transmitter lead, there are only diodes and the separate receiver switch in the receiver side. 73, Jerry, K0CQ -- Entire content copyright Dr. Geral
