Some advice is being sought for the RF Power amp in my Omni 546 series C. First the history of what happened and why. As mentioned earlier on this list I obtained my Omni-C unused, new in a box over
Jerry, Thanks for this tidbit, the elbow has been removed and it will not go back in. The Omni has two stages, one with the MRF 476 and one with the MRF 458 / MRF 454 (direct replacement). At presen
Hey guys (and gals), I signed up to the Tentec reflector for help, information, discuss TenTec equipment and not some other brand. If I look at the number of postings this month alone deidcated to th
How about using the frequency mite ? http://www.smallwonderlabs.com/swl_frq.htm Marinus, ZL2ML _________________________________________________________________ Buy, rent, invest property online toda
Jerry Thanks for the input. The 33 uF is not in the ALC loop - the low level driver board takes the output from the TX mixer. From the manual: (quote) " The first two stages, Q1 and Q3 are ALC contr
After an absence of 24 years I got back into ham radio. Lots of chances have happened in the intervening period and back int he 80's the only connectors I could lay my hands on was either BNC or PL23
Ken thanks for the feedback. I have got locally a dealer in obscure electronic goods who has several thousands of N connectors from "cheap" nickel plated through to silver and stainless. He also has
Lee, Higher powered audio amplifiers have a time delayed relay switching the speakers after the amplifier has switched on. When powered down the relay drops out before the speakers give a pop as well
I was leaning towards the TNC connectors and was gathering info on best places to buy. However I finished up going with the N connectors: on our local auction website someone was selling four Huber S
While doing research I came across an interesting article of market share of the different types of connectors and the market share of the different manufacturers. I found it may for interesting read

Gents (and Gals) Although I mainly work 40 (and occasionally 80 / 20 ) I like my S-match (design by PA0FRI , a twist on the old link coupled ATU) with its galvanically seperation between antenna and
I am waiting for the new drivers and new finals for my transceiver to arrive (should have been here already). One thing has just cropped up and perhaps some of the more up-to-date knowledgeable ones
Jerry and Stuart, thanks for the feedback. This was just the information I was looking for. Not having to mess around with grease for the drivers really appeals to me, especially since they are stuck
Have not followed the Bazooka discussion in its entirety since I feel it goes a bit far OT. However one of the last postings raised a question in my mind due to the reference to the Late Cbik with wh
Yes, this is what others have mentioned using balanced wires. Rather than addressing the symptoms it's better to address the cause. If the antenna is not balanced then we better try to balance the an
May I suggest to prefix any non TenTec discussion with OT (Off Topic) instead? In that way only once a filter has to be set up, not only for current discussions but also for future discussions. Hopef
The 228 uses a 42 position switch for switching the inductance, the 229 has a roller inductor. When the power amplifier stage consisted of tubes the roller inductor with its "infinite" adjustment was
Recently I obtained a new Huber Suhner surge protector and 4 new Huber Suhner N connectors at a bargain price. Am very impressed with this professional gear - in all the years that I have bought PL25
Jerry & Jim Although it is not as loss free as pure open wire I am fond of the 250 Ohm TwinCom. It can be laid like coax and gets little (if any) interference from its surroundings. http://www.titane
