Re: [Elecraft] K2 80M No BFO

Curt, I have to disagree with your assessment. The BFO must be active even to hear a "rushing noise" - this is a fact with product detectors. What I am also saying is that there is nothing band dependent about the filter center to BFO alignment - it will be the same for all bands. The fact

[Elecraft] K2 80M No BFO

Rarely operate 80M, but today wanted to listen to the NAQCC net on 3575. Amazingly, there was no BFO. I could hear the CW as rushing carrier noises, but no tones. CW on the other bands receives just fine. LSB receives fine on 75M. Everything was fine on 80M about a month ago. Thoughts? 73

Don, thanks! 6-32 did fit but with a little wobble. I just went downstairs and ran a known 6-32 nut up a known 6-32 stud and it also wobbled a bit! So 6-32 it is after all! Funny how one can fail to notice the obvious for so long... Guess I've spent too much time messing around with plastic

Re: [Elecraft] Day 1: Fried something already?

Owen, You have the procedure correct. Yes, the caution about lifting one lead of T4 was if you want to investigate the relay further. Because of the ground at the secondary of T4, if the relay is set, you will see zero ohms between all the pins except for the coil - that should not surprise

Hi Don - Many thanks for your help! L25 and L26 look totally clean so I'm not going to mess with them for the moment. I'll look into testing K12, though I probably won't get to it until tomorrow. Can you clarify what I should do to set up this test? 1. Tune the K2 to 40m 2. Power off 3. Che

Re: [Elecraft] Day 1: Fried something already?

Owen, Armed with that further information, I suspect the relay contacts. Examine the inductors anyway to see if there is any evidence of charred turns, if so, re-wind them. You can check the relay contacts of K12 with an ohmmeter. If you set the K2 to 40 meters, Relay K12 should be in the

[Elecraft] small feature change

Hi Elecrafters the option "TX DLY" could be configured between "0" and "20ms" currently. Maybe thats enough for a small switching SW-Amplifier but it is not enough for VHF transverter work. Could it be expanded to at least 100ms or even more? -- /*73 de*/ /*Wolfgang DK9VZ*/ w...@dk9vz.com

Re: [Elecraft] Day 1: Fried something already?

I just tried the test for the inductors. With no antenna attached, I read 1.7k ohms from antenna center conductor to ground (tuned 40 meters, then powered off). I am able to read continuity across L25 and L26 though... I think I can borrow a Fluke meter from a friend which can test capacit

Re: [Elecraft] Day 1: Fried something already?

Owen, That all means that you have a problem with the 40 ,meter low pass filter.L25, L26,C225, C226, C227, C228, C229 and the contacts of K12 are all potential suspects that need to be checked. One quick test would be to set to 40 meters and power off (the relays are latching types) and measu

Hello Don, thanks for your prompt reply (again - you helped me diagnose my misplacement of C6 in the BPF section a couple of weeks back). I do not have the KPA100, just a base K2 with the SSB module added. I was using an external Tokyo Hy-Power amp when this mishap occurred. I've just done

Re: [Elecraft] APF and audio limiting

Mike, Don's explanation is good. Remember, AGC does not "bring up" the level of any signal ... only the audio gain control will do that. AGC simply *reduces the IF gain for signals above the AGC threshold*. Although it is intended as an analysis of the K3's AGC behavior, the study by Jack Smit

Re: [Elecraft] APF and audio limiting

It's not nit picking when someone corrects your incorrect description. AGC action seems to be one of the least understood facets of the K3 and putting bad information out there about it doesn't help. You were wrong ... Joe is correct. Don't take it personally. Dave AB7E On 11/6/2010 6:

Re: [Elecraft] Day 1: Fried something already?

Owen, Most likely the bandpass filter is just fine, I will take bets that you effectively transmitted into an open load and something in the Low Pass Filter is now awry - A shorted capacitor is my first suspicion - but then you may have just zapped diodes in the KPA100 wattmeter. But, break
