FT-243 40m CW Quartz Crystal (1) Amateur Ham Radio Band 7 MHz - TESTED
USD 19.99 USD
Your choice of 40m Ham cw-band crystals. These are all real pressure-mounted crystals, no old cases stuffed with modern crystals. All of these are tested and guaranteed. You are purchasing a working crystal. All have been checked in a test oscillator checked for reliable keying an actual Johnson Adventurer under load to looks for any of the usual pathologies. Many I've used on the air at one time or another. Actual oscillation frequencies are near what is marked, consistent with the aging and tolerances typical of this stuff. Expect a little variation depending on circuit constants. Listing is updated periodically as crystals become available. You can choose an available crystal frequency from the list. The photographs are of the actual crystals for sale. Zoom in on the photographs to get a closer look at an individual unit. If you wish to purchase more than one item, please use the add-to-cart option before checking out. I'm happy to combine shipping on multiple items. Many of these also multiply up to good frequencies on 20, 15, and 10 meters. You can do the math :-) Go have some fun!
