[Heathkit] Heathkit Digest, Vol 83, Issue 3

[W. Harris]

Check the 3395.4  crystal on the carrier oscillator (V16A). That crystal is used in both the CW and TUNE positions and feed the 3395.4 signal to the product detector (V13C). Check to see if you go to the TUNE position if you tune the rig and  get output. If not then that crystal isn't working. Check the soldering around the crystals on the modulator circuit board. There is no BFO.

> I am new to the list. I have been reading through some of the old postings with no luck. I am looking for an answer to a question.

> I have an HW101 that I restored to working order. I completely rebuilt the power supply, and have gone thru the radio and replaced several resistors and capacitors. Checked all voltages and everything seems fine. I had this radio in service for about a year since aquiring it in August of 2006.
> 
> I have not used the radio for a while since aquiring a Kenwood TS-830 complete station in January 2008. I tried to use the HW the other evening for some CW work. In receive, I can hear static and not a clear tone on CW with the switch in the CW mode. If I move it to either LSB or USB then I can hear the tone just fine.

> Any ideas as to what could be the issue? I have read thru the trouble shoot portion of the manual as well. I was told it maybe the BFO? Not sure if what I am looking for and if there is a simple adjustment? Thank you.
