Hi Joe, The choke/coil I have is molded, 1" long x 1/4" diameter. Bob

I can't open deja vu on my cell phone.Most receivers with single crystal filters adjust the IF to the crystal frequency.? ?A very few,? like the Collins 51J series need to have an exact IF

Hi Steve again I believe from previous posts re the sx-110, you are trying to understand and implement the original instructions, rather than use newer techniques. Due to your previous posts I have

You make a good point. And the truth is that I have both a NanoVNA and a TinySA. Haven’t done much with the NanoVNA yet – it might be time to learn something new. 73 – Steve, KW4H From:

I think they are just saying to rock it back and forth in freq to make sure it's peaked. A generator of that time period was not dead stable and they had no digital read out of xtal freq. If you are

All, The IF alignment procedure as spelled out in the SX-110’s Operating and Service Manual is a little confusing in one spot (see attached). In step 2 you adjust the top slug of the first IF

Bob: picked up one from Mouser and I am not sure about it. Can you tell me it your? choke is a molded or a open coil type? Physical size?? Joe, direct : via ARRL.NET

Hi Joe, I have a 4.7uHy choke that you are welcome to if you are still looking. From looking at the schematic, I think this might be close enough. Let me know if you want it, and I will drop it in the

The crystal came from AF4K Crystals. Good service and a fair price. They have a wide range of crystals available. 73 – Steve, KW4H From: <[email protected]> on behalf of Dan

Hello Richard, I understand you are wanting to sell as a complete lot, however if you would at some point like to sell the ha-8 and ha-10 separately please keep me in mind. I would love to add them to

Steve, very nice, well done. Did you mention in an earlier email where you ordered the 455.000 crystal from? Dan WB4GRA

Steve: sorry about your wasted time.. at least they let you go! Thanks for reply, with good news on new xtal. Very good pic of xtal in radio! Seems that old one was not intended to be moved or maybe

Apologies for the delay in responding – I had jury duty today, and was (fortunately) blown out the airlock. It seems that the moment the attorneys discover you have a technical background and might

Yes Richard what I sent is likely about a permanent shift in frequency; it likely does not closely relate to the original posting, but is an aside, closely related to xtal frequency shifts in general.

And for those non-microscopists/ non-biology majors: ?BSE = backscattered electrons?SEM = scanning electron microscope?Bob K3AC

I suspect this is not a plated crystal but a plain crystal held between plane electrodes on both sides.? ?It seems to me that migrated solder would cause a permanent shift in frequency rather than

steve I just ran across this,but but there is not enough info to know if it could be related to your investigation. "This is a BSE SEM image of a quartz crystal that reportedly shifted in frequency.

I have for sale the following 16 Hallicrafters radio items. I can no longer afford the space or time to use them. I have previously operated most if not all of the items. I know some of them worked,

I thought the same thing. Its in the works. *K2WH Bill's QRZ Biography ( https://www.qrz.com/db/k2wh ) * ---------------------------------------------------
