Re: [Elecraft] BFO resets itself after cal fil (K2)
Aha! Then I did not fully understand the inner workings of the K2. I just looked att the schematics and noticed the BFO and the mixer. Out of that I made the conclution that the BFO value must change the pitch. So what you are saying is: During filter setup, it is normal for the pitch to change but when I press XFIL the save-routine inside the K2 is compensating for the change and restores the pitch to its original position? Is that correct? Which in practice means that I cannot adjust the pitch manually (like on an old radio), it's up to the K2 routine to set the pitch. ./Erik 2012/4/29 Don Wilhelm > Erik, > > The K2 will preserve the pitch when the BFO is changed.

Re: [Elecraft] BFO resets itself after cal fil (K2)
Don, tnx for the answer. Yes, the difference was small. Tnx for the info about 20 Hz, then I now the limitation of the construction. Yes I can use the FL1 (open) as both TX and RX (well of course TX is alway using FL1). But if I want something more narrow I like to use FL2 - FL4. And now I know that I can get in 20 or so Hz if I work hard enough. :-) But the main problem here is that I cannot adjust my filters at all right now. :-( I can move the BFO (change the pitch) as long as I am in cal fil but as soon as I save the filter and return to listen the pitch has changed to "default". The BFO-value _has_ changed, it _has_ been saved. (I see the display showing BFO freq for a short time). But still - the pitch is where it was before I changed the BFO-value. And I have changed it much - like 50 to 100 units. USB, LSB, CW - the mode does no difference. So: Received pitch of the signal transmitted from my 2:nd TRX: 1500 Hz The BFO value is (lets say) 128 I change the BFO value too 100 I hear (and see on the waterfall) that the pitch is changing. I press XFIL (to save) Display shows BFO freq for a short time. I press XFIL a couple of times to "get round" to FL1 again. The pitch has now jumped back to 1500 The BFO-value is at it's saved 100 I can now lower the BFO value once more and when I come around the pitch will be 1500 and the BFO is saved with the new value. Isn't it suppose to work like: Change the BFO to get the correct pitch Save Return to the filter and the pitch is where you programmed it to be. 73 de SM0RVV ./Erik 2012/4/29 Don Wilhelm > Erik, > > Do you see the BFO frequency flashed on the display when you exit?

[Elecraft] BFO resets itself after cal fil (K2)
Hi all, I decided to recalibrate the filters in my K2 because I noticed a small RX-TX frequency difference which made it hard to use my NUE-PSK. But I didn't get the calibration working... I enter filter calibration menu. I select FL1 in open-mode. I adjust (in RX) the BFO and watch the audio move on the waterfall (change pitch). All seems 100% OK. Then I press XFIL to save the value. (the freq-probe is in TP2 - duoble checked). When I then return to FL1 the pitch is back where it was from the start. I first thaught that the value did not get saved, but after re-checking the BFO-D/A value it has been saved. I then tried to measure U8 pin 16 to see if the control voltage is changing - yes it is. The voltage changes when I change the BFO-D/A value in cal filter. The value I choose will be saved and I can measure the same voltage when I return to FL1. But the BFO keeps resetting itself no matter what value I choose in cal filter. The most strange thing is that the BFO changes as long as I am in cal filter menu, it resets itself when I change filter (saving the value) I had the SSB option in, but in the troubleshooting I removed it. The behavior is still the same with or without the SSB option plugged in. So... Can anyone give me a clue what's going on here?

But that was really difficult! As soon as I rotated a tuning-knob the K2 adjusted it's power. I found it impossible to tune the antenna :-( Is this the way it should be, or am I missing something?

Just about ready to start the construction of the new stabilizer circuit board. Jim, My #4904 is in the exact same level of rediness as yours. :-) I only having some troble understanding how I am going to success with so much empty holes on the RF-board. It feels nearly impossible that it will work... Anyway, now I'm going to take a few deep breaths and continue one piece at the time. Duoble-check everything and it hopefully goes well... 73 de SM0RVV ./Erik ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Masking tape K2?
Hi, I'm building K2 #4904 as a follow-up to my K1. My manual says (at page 29) "Some holes in the front panel was masked..." I have no mask-tape over the holes, and there has never been any tape over the holes. It's painted grey on both sides. What is the purpose of masking? 1) Just a manufacturing thing? 2) To get un-painted metal for better grounding of the box? How do I move on from here?

[Elecraft] To mod or not to mod, thats the question
Hi all, I'm going to order a K2 in the nearest days. I'm alreday built a K1, #1978. (If you start to build, it's hard to stop... :-) To the question: I see many articles on the Net about different modifications to the K2 rig. How is this reflecting "the real wold"? Are there many of you which have modified rigs? Or... Are the majority using standard K2 exactly built from elecraft's manual? The main question I'd like answered for myself before I start building is if I must have in mind some of the modifications during build-time.
