Checked it out. Radio - amp - swr/per meter - dummy load. All fine. He had a cluster _____ of coax, switches to switch different antennas to ??? I showed him the radio and amp are fine so he has to

I'll let you guys know what I find. I'll see it Tues eve. Bob W4JFA

That is very odd. .. I have owned several LK amps. They will cover the entire band in the No tune. The SWR needs to be fairly low however, Most people do not have an antenna that covers the entire

All the LK series NT ( no tune) amps have several small load and tune capacitors. You must pre select the frequencies you want to operate on each band first. ?Then you use the internal load and tune

Hi all, Tomorrow I'm going to see a friend that has some kind of problem with his LK-450 NT amp. At this time I have no idea what the problem is due to inconsistent information. But I have a question,

Yeah, Chuck – that must have sucked ! From around 2500W PEP out down to 1500W PEP out. Ouch ! But, as you say, not a big deal to any of us. Sent: Friday, March 22, 2024 6:04 AM To:

Good day Chuck and Group., You were well stitched up, it means the FCC and ARRL thought a 4-1000, 100% plate modulated with all the trimmings was equivalent to a TL922 or SB220, amazing !! Our

That’s great news, Michael. Congrats !

Well, there you go….250W AM carrier for 100% modulation. An Upgrade for you guys but when they did that with the 1500W PEP for us USA AM guys years ago, it was about a 3 dB hit. Not that anyone

Good day John and Group., The day after I posted, the RADCOM dropped through the door with a synopsis of the new licence variations , 1 Kw pep it is. 73 de Michael G3TCA., ==================

Understood. Wouldn’t that be wonderful ? A licence-approved 4kW PEP !! Can’t see that ever happening……officially. Luckily, it happens all the time, unofficially. Especially on this reflector !

Good day John and Group., We've only heard the figure 1 Kw banded about at the moment, got to wait for the details in writing on our new licences. When I made the post I had my tongue very

Hi Michael. 150W DC fully modulated = 400W PEP. So, I imagine your new granted level would be 1kW PEP….? This is the new power level we were asking for down here in VK. Our existing legal power

Good day Jim and Group. I reckon your suggestion of using a Pi-net on it's own is the best way to go, can always up the Q a bit and see what happens. That line 74 where GM3SEK uses that formula

On the gm3sek software, it does a calc, to arrive at image Z...called 'RM'.? ( sq root of? R1 X R2).? R1 = transformed plate load Z? ?R2= 50 ohm output Z). Fact is,,,? u can enter any value u

Does anyone know where a replacement relay can be obtained?? Or the manufacturer's name and part number? Thank you.

Good day Jim and Group. Excellent effort as always Jim.? In the dim and distant past before spreadsheets we used to make Peter's (GM3SEK's) Rm as 200 ohms and the Q of the eL coil as 2. As

Thank you, Jim. I’ve had to reverse engineer other people’s results in the past to find out that we were actually talking about the same thing. I have learned one thing in my 40+ years as a

Finally got it all figured out.? It's a bit of a complicated mess.? There is a total of 5 different? 'Q's'? involved on the GM3SEK? PI-L spreadsheet. The short of it is.... I had to maladjust the

He didn’t, Mike. He said “playing dumb”. Not the same thing at all ! Good to see passion is not dead around amplifiers.
