I noticed something interesting for the first time about my Omni 6 option 3. two nights ago I dropped out of a phone qso on 3885 to go to bed. My usual practice is to "listen out" while I power down
Tnx Don; I do not consider it an error or bug in the rig, however I think it should have been designed to operate CW anywhere, if it is in fact the case that they did what I suspect. 73 Rob K5UJ ____
At a hamfest flea market. I got mine a few years ago for two dollars. Just keep a lookout. They turn up with prices varying but usually under $10. 73 Rob K5UJ _______________________________________
I don't sell any of my Ten Tec gear very often but when I do, I offer it here first. For Sale: Ten Tec model 238A L network tuner The price: $350 firm USPS M.O. or personal check* Why I am selling
according to RF Parts, the replacement is the 2SC2166. Link to datasheet below. www.yoyocomponents.co.uk/datasheets/2SC2166_eleflow_DATASHEET.pdf It's not a bad idea to actually answer the guy's ques
you don't need caps from ten tec which would probably not be all that good anyway. They usually used disc ceramics which were sub-par when it came to handling continuous duty current on 160 m. I'd in
This doesn't change the fact that every shortwave broadcast station in the world uses open wire line to balanced antennas, usually rhombics and dipole curtains, for covering multiple assigned freque
I suppose it gets down to the meaning of "badly matched." If by that you mean for example a 1/4 wave dipole fed in the center then I'd say nothing should feed such a load because it's pretty close t
A full wave center fed dipole will be voltage fed and have a Z of around 5K ohms and put a vswr on the line of around 10:1. The line loss is negligible because it is a balanced line with an air diel
It's important to understand that any antenna is better than no antenna and I'm speaking of incremental improvements in terms of an antenna _system_, i.e. the matching network, feedline and antenna,
Not everyone. Hams and companies who did the right thing and continued to buy caps from AMERICAN COMPANIES employing and paying AMERICAN WORKERS, companies like Illinois Capacitor and CDE had no pro
I see the complete opposite at least in North America. The level of activity on average on HF is much less than it was 40 years ago. Back then 160 m. was wall to wall at night. 80 m. cw was jammed.
The same thing has crossed my mind Jack. Or given the stampede to SDR rigs, class D boxes, the latest XQP3000 rig blah blah, there won't be anyone left who can converse and understand all vacuum tub
It doesn't matter because they never actually use them -- they just send email all the time. That's how consumer appliance hams are. They could just as easily be talking about a TV set from Best Buy.
I had one of those 238 matching networks once and sold it. There are a few commercially manufactured ham feedline/antenna transmatches out there that are decent but they are sadly no longer made. The
That's a specious comment. Cars are not antennas or impedance matching networks. You are equating mass production needs with a few people homebrewing. "fairness" is irrelevant. I'm writing about bui
Someone complained about the tuner topic. Two guys posting emails on a reflector that routinely wanders all over the place on anything unrelated to Ten Tec. You gotta laugh sometimes. You can call it
