Garry, You don't need WWV to do the "N6KR" method - you can use any reference signal of known frequency and accuracy. Subtract the BFO frequency from the VFO frequency and that should be the frequency of your reference - if it is not, then adjust C22 until that condition is true.. With WWV (

Thank you Don. I think the most confusing part of all was, I was looking for various width settings for the ssb filters. Eventually I came to realize that I had to use the other filters for reduced bandwidth for ssb. After that dawned on me it was relatively easy. Or perhaps I still have not g

LS, Great progress. Congratulations. Make note that the 4.000 MHz reference oscillator setting that is correct may differ slightly from exactly 4.000 MHz - so don't exhaust too much effort on getting it 'right on' using any kind of measuring device - there is a better way. After you have your

Ok, thanks for the info gentlemen. I finally ran out of capacitors and resistors last night (thank goodness!) and seem to be in the last stages of building the transmitter and low pass filters for the rest of the bands. So I guess it's getting close to being done. Need to resist the urge to rush n

Garry and all - at least those who are building new K2s. Yes, the filter setup is a bit "tricky", especially when using filter widths wider than 1.00 kHz. The reason is in the varactors that have shipped with the more recent K2 kits. What that means is that a filter width that is indicates as

Congrats on the K2 receiving on 40. It's only a month or so back that I finished mine so easy for me to remember the thrill of hitting the switch and having it come up working. I used mine on cw for a week or so then went on to the ssb board which allows digital modes as well as phone. Still us

I'll add hearty congratulations as well. L33 is indeed the tricky part (don't ask me how I know, but Don's advice to re-heat suspicious solder joints comes to mind) and you've done well to leap this hurdle. You'll be golden from here on! 73, Mike K8CN lstavenhagen wrote: > > > Again, I didn

Hi all, In case anyone's interested, I got through with test and alignment II on my K2 last night. Everything seemed to proceed normally. Again, I didn't seem to run into any trouble. My first kit and all I'm expecting to have busted something but so far all OK (even the install of L33 hi hi). M
