Скачать или смотреть Omega Electronics Company LT-5 CW Transmitter up and running

Found this little transmitter at a swap this morning - have never seen one nor heard of Omega Electronics Company (San Diego). Dates from the 1970s.

When I first powered it up, it was dead (of course). I opened it up and immediately noticed a spot of corrosion on the single transistor collector connection. A quick clean up of the thin wire and transistor case, and I resoldered it. Didn't expect much but when I powered it up, it WORKED!

Using one of my many FT-243 crystals (7.114 in this case) it delivers around 1-2 watts to the antenna with a fairly decent CW note.

The only real drawback is there is no TR switch (even a simple toggle switch) and jack for a receiver connection - so to use it you must use an A/B switch that is external. I have a strong feeling not many of these units were ever really used in the field - but were more of a "shack QRP novelty"

But either way, it's up and running quite well - very nice looking little transmitter!
