[Collins] Crystals for S-Line...

[Dr. Gerald N. Johnson, electrical engineer]

Burghardt Amateur Center
http://www.burghardt-amateur.com/Burghardt/HTML/main_frame.html has a
gang of crystals on their used list. Click on used, then on list as text
and run down to almost the end of the list. They are listed by crystal
frequency. Working range is 3.155 below the crystal for those that end
in .x55 and 3.155 below twice the crystal frequency for those that end
in .xx75.

Surplus Sales of Nebraska has S-line crystals at solid gold prices.

Otherwise good crystal makers can make them custom. ICM has been good
but I hear their prices have risen astronomically.

Which S-line transmitter and receiver do you have? Those with the extra
crystal board (shuttered window around band switch) have the stock
crystals underneath.

If the pair is used strictly connected for transcieve whether using the
transmitter or the receiver PTO, crystals are only needed in the
receiver. That does limit DX splits to the same crystal range. But the
transceive connection does that anyway, the cables have to be
disconnected and jumpers in the transmitter set for independent
operation to split further, then the transmitter frequency has to be set
manually all the time, there's no transceive practical because
transmitter and receiver crystals won't match closely enough.
