These crystalsare compatible with 75Mhz GWS radios and receivers.
The receiver crystals are the mini-style UM-1 to be used in all of our GWS antweight receivers. If you need both, you need to order the TX and RX separately, we do not offer a 'set' of the two.
If you select "no channel preference" and your order is for a TX and RX crystal, we will provide you with a MATCHING set of whatever we have available in stock.
Although we strive to have all these channels in stock, some may be special order, and may take up to a week to arrive.
