Don, My replacement BFO crystals arrived today and I installed them. My BFO range is now 5.66 kHz. FIXED! Thank you!
I have to add a note about what I call "Elecraft Mojo". The crystals were back ordered so there was a delay before they could be shipped. The package was sent Friday from California on its way to Florida. USPS web page said that the package would deliver on Monday. I checked the tracking info this morning (Sunday) and it said that the package was at the local sorting facility. So, on track for a Monday delivery. I went out to the mailbox to drop off an outgoing letter this afternoon and I was surprised to see a Priority Mail box inside. Sure enough, it was my Elecraft parts order, delivered by the USPS ON SUNDAY!!! To make sure I wasn't losing my mind I checked the tracking info again and sure enough, it was sorted and delivered today. I have NEVER received regular mail on a Sunday. Just more of that Elecraft Mojo. And, of course, my tiny little order was treated with the same urgency and respect as when I bought the radio new. What a great company. Now, off to finish the alignment! Thanks again and 73 Mike M. KU4QO On Sat, Sep 30, 2017 at 10:53 PM, Mike Maiorana <zfr...@gmail.com> wrote: > Don, > Thank you again for your very detailed response.
