The correct "4 line" (T-4 series & R-4 series) crystal frequency for 17
meters is 29.1 MHz, not 32.5 MHz.
Foper MHz + 11.1 = Fxtal MHz
18.0 MHz + 11.1 = 29.1 MHz
32.5 MHz is correct for the TR-series, if they could be tuned up on that
band.

Crystals For Sale:
I found an assortment of crystals that can be used for heterodyning
crystals for Drake, Collins, Heath, and other rigs.
HC-6 32.50 MHz
This crystal used in the Drake "4 line" should give operation in the 17
meter WARC band. It will give 18.0 to 18.6 MHz operation. $12
The following are HC-6 Crystals, with the actual crystal frequency
listed in MHz.:
7.98, 9.5, 10.5, 11.5, 12.0, 15.0, 16.0, 17.0, 24.7, 25.0,
29.0, 30.75, 39.0, 41.9, 42.7, 44.5, 46.0, 46.7, 49.9, 51.1,
Other crystals available:
1000.00 KHz for crystal calibrator
FT-243 Crystals for 80, 40, and 10 meter ham bands
3500, 3625 (W), 3675 (W), 3825, 3838, 3850, 3980, 3990

7404 (29.616), 7410 (29.64)
The FT-243 and HC-6 crystals are $8 each.
Does anyone have an older two meter ham rig and need crystals?
Maybe I can help. I have some of both transmit and receive 2 meter
xtals. Most are in the 146 and 147 MHz band segments, with very, very
few in the 145 MHz segment, and none in the 144 MHz segment. These are
for ham rigs only, and not commercial rigs.
These are all the small HC-25 xtals, like were used in most of the solid
state 2 meter mobiles and HTs. Please e-mail the operating frequency you
need. I have them listed by operating frequency and rig, and not by
actual xtal frequency. Send the frequencies you need (transmit or
receive), and the rig that you have, and I will see if I can help. I
have cross references for the various rigs, so I will know what you need
if you give the rig.
The 2 meter crystals are $6 each.
Prices do not include shipping from Florida.
Thanks.
