Need Crystal freq. for 28.5 mhz in TR4C
¿ªÔÆÌåÓýGreg:The TR-4C was originally supplied with a 43.0 Mhz xtal for that range. Back in the '70's there was far more activity above 28.5 than there is now.? The 42.5 Mhz xtal for 28.0 - 28.6 (+++) coverage was optional, as was the 43.6 Mhz xtal for 29.1-29.7 Mhz. If you look at the pictorial of the chassis top in the manual, you will see the xtal positions marked. 73 Peter VE7PS On 2021-03-26 1:18 p.m., Greg Anders

Just picked up a TR-4C that needs some re-calibration work, but it is operational.? Made a few contacts on 40 meters with it tonight.
I wouldn't mind finding a set of 42.5 Mhz xtal for 28.0 - 28.6 and the 43.6 Mhz xtal for 29.1-29.7 Mhz.? May as well get the optional crystals. It did come with the Noise Filter. Cowan N5QDH |
