Jim, I am NOT trying to deny reality by saying the CW bands are hopping, I do hear them. Admit it, you have NEVER BEEN AT MY STATION TO KNOW different, that clearly demonstrates that you are in denia
You say -- The biggest amp in the world won't help your reception. I say -- Yes it can HOW? By asking the OTHER guy to turn on HIS amp. QRP is fun only when it is a choice for both sides of the QSO.
Hello Jim and group, I respectfully disagree. Tube amps are not a thing of the past nor will they be for a long time to come. I would like to point out that I own and use both Solid state and Tube am
I am very familiar with that as I built one also, The issue is anyone who builds one must face that issue one way or the other. Any mistake and it is over. As I said, I have both LDMOS and Tube ampli
Talk is cheep. Ask them if they will put that in writing? Also ask if they will put a penalty clause stating they will give you a $100k payment should they fail the 15 year test. After all if it was
Actually you do NOT have your crystal ball to predict the future so your statement is NOT based in fact, only an opinion. I prefer to go with facts, so hear we go. FACT... Because we can not see into
Larry, You made and proved my point for me. The transistor you mention is NOT an 1400 watt class (as I specified in the email) in fact your transistor is not even close, it is closer to 140 watt out
Kevin you DON'T get it at all. You could not be MORE wrong, I DO love solid state. I have repaired more solid state amps than tube and I bet way more than you have repaired. IT is just that everythin
I remember using Lissajous in the early 1970's when I worked for RCA servicing two way radios systems. I laugh at it now, but for about five (5) years using a Cushman service monitor and analog O-sco
Hello Chris, I have a feeling you do not mean output SWR, I think you input (from exciter) is high. If that is what you do mean, then my first guess is the fillimate is out. Fillimate most often burn
Hello Carl, I worked for RCA also. When and where did you work for them? 73, Bruce, W8HW == My ancient Bird 3KW load built for RCA still has its couple of gallons of PCB's. I check the smell every fe
Once you pull it out of the box and blow it up, it can never go back in... How'd it fit in the box? --Mike, WV2ZOW http://doctorgary.net/qrp.jpg 73 & have fun, Gary KA1J _____________________________
Hello Dick, Keep both in. While the resister does the most protection, I HAVE seen resisters that have shorted. This is rare as most time they either open or increase in value, but shorting can and d
Hello Bill, I believe your amp uses tube 3-500. If so it is a quick heat up (Less than one second). By the time you throw the standby switch to operate, and then turn to your radio, it is ready to go
I have worked on many of these amps as well as many other amps. More than one issue will cause this, but the first one to think about is did you replace the resistors that shunt the caps that you rep
90% of the time it is a diode on the hv board that is near the edge. If I were home, I could give you the exact one, but won't be home in Florida for a week (Sept 3). I repair amps and have worked on
Roger is correct. Fast (semi break-in) works very well and is better and safer for equipment than QSK. Additionally, I have seen the same issues with speeds above 35WPM in some cases. On 10/16/2018 1
You are so correct Victor. I have a special problem with my call (W8HW) on CW as often would get logged as "W8SW" if I only sent it once. I quickly learned to send my call sign two (2) times in pile-
Amplifier problem? I am sure that old amplifier still has lots of life still in it. All you need is a solution. I have been servicing transmitters since 1971, now retired in Florida. Feel free to ema
