Dear Mark, Years and years ago I had the opportunity to work with John. ., who held the 1934 patent on facsimile science. The original telefaxes were drum types, and they actually transmitted phoptos,

Here's a ham radio link to the general discussion. I'm right in the beginning of a tetrode project and working on the steel chassis unit to house the outboard 2 amp power supply. All the fans,

Rich, Thanks. Yes, sorry for the wording. John k3ct@...

Maybe you will get a chance to work for the that great company in the future. I hear $8 an hour buys a lot of amplifiers. Bet you would love to join a union if you were making that big $8. I hear

my Wife's best friend jost had his job out sourced to mexico to save a couple bucks on the lego toys. Maybe it will happen to you and you may catch my point. He has over 20 years with lego and 50

** Hello, John == There should be one plate choke for all 4 tubes. Do you mean 4, R/L VHF parasitic suppressors? ** 1.5:1 is typical. >5:1 is not. ** If one connects a 50-ohm load across the Load-C,

Yes, equal brightness across all four tubes. The plate chokes on each tube look fine also. The input SWR varies anywhere from 1.5:1 to >5:1 while I am tuning the output. Is this expected? It causes

I have a HA-10 Warrior that is working well in most respects, however, there is an issue with the meter. The meter will show HV, however, when I want to look at the grid or the plate, the meter drops

Good Evening, I was operating on 20 meters this afternoon with my L-7 on the SSB mode. Everything was normal for about an hour. Then I noticed in the middle of a QSO, the grid current meter started

So what if it costs more? Give me a break! Some of you elitists may be able to take that attitude, but the rest of us have to worry where our money goes. If I took that attitude I would have to forget

Exactly correct. Unions have destroyed more US businesses than we can count by demanding more wages and benefits than the employer could stand, all with no regard for anyone but themselves. That's why

I prefer to keep our money in America and have Americans working. So what if it costs more. Are you willing to work for $8 an hour to lower costs? This should be a closed loop system like a lot of
