[Boatanchors] Question about a Heathkit crystal Frequency

[Rodger Singley]

Bry,



I am sure that was a mistake or typo in the email.  3396.4 Mhz. is the standard USB/CW crystal for the SB and HW lines which used a 3.395 Mhz. IF; the exception were the HW monobanders but they had an IF in the 2.3 Mhz. range.    The only “oddball” crystal I am aware of in the regular SB series is the 3392.110 Mhz. RTTY BFO crystal in the SB-303 receiver.

Subject: [Boatanchors] Question about a Heathkit crystal Frequency

Hi Heathkit fans!


I need your advice on supplying certain crystals. I think this was about some of the SB series or HW series radios...


Someone asked me a while back for a 3996.4 kHz crystal

for one of their Heathkit radios.

I want to be sure this is the correct frequency and I had lost the e-mail. I needed to be sure it is not 3396.4 kHz that is needed or something...


Is this a standard crystal that was used - perhaps for USB or LSB selection in some of the mid-century rigs?


We are gearing up for some more production and wanted to make these available along with some other odd ones like:


29.895 MHz

and

37.895 MHz.


Thanks for any advice. 73 & DX.
