[Elecraft_K3] KPA500 finals blown
As one who has seen the worlds fastest fuses go bang, the causes maybe many. Usually the higher VDC at load will not necessarily blow them unless it exceeds the max level by a considerable about. They

[Elecraft_K3] K3 - background hiss (noisy K3) - update
Might I ask if you have tried to isolate the source? In the tube days a gentle hiss was attributed to the electron bombardment of the plate from the cathode and was never "completely" eliminated. Whil

Hi Larry, These were made in Italy by RMI. I have used one of the HLA-300V Plus for about 4 years with my KX3 and the FT817 before with ZERO problems. http://pa0fri.home.xs4all.nl/Lineairs/HLA300/hla3

[Elecraft_K3] K3/P3 video display on AM vs SSB
Thanks Joe, found the peak hold. Still on my P3 the blue modulation line is a slow arc but unless you are looking at the really low audio tones, -500 Hz, which are about -12 dB, the rest of the audio

OK, as stated, I ran the peak hold which actually the average with a setting of 20. No difference, sorry. You have to perform the test to see it your self. No more on this thread unless P3 tech suppor

Yes, Joe, But the difference is the display is the question. WHY? My 8920 show proper power distribution on the sidebands, the P 3does not!!!!!!! Mel, K6KBE

OK, Alan, Thanks for the input. Here goes. I am monitoring a friend near by, 15 miles. I took care to have him set up the 100 W SSB station and his 1KW AM station like this. In CW mode, send a 100 W m

Yes, Alan, I understand all of that. Here is the question. Why is the sideband power on AM on the same band, 75 M, less than the displayed signal on SSB. An example. Watching the 100 watt signal on 39

Final comment after some bench testing. I put the signal generator with 1 KHz tone at 100% modulation into the 8920. Sidebands were 6 dB down. I then put the signal generator on 7.2 MHz at +20 dBm int

One other thing Grant is that when a BC station transmits a single tone, the sidebands at averaging or open should be 6 dB down. It never is? As a side note, my HP 8920 shows a proper power distributi

Tried that, still the sideband sweet spot, Most power is still down considerably?? Not so with the SSB. That is the CW level of peak carrier and the SSB are about right. Just confusing. Mel, K6KBE
