All of our transmitter and receiver kits require alignment after construction. On synthesized units, frequency can be changed up to two MHz without retuning coils, but for a larger frequency change, some repeaking of tuned circuits is required for optimization. The new style coils we use take a special .060 inch square tip tool, and you can break the slugs by using a tool which doesn't fit properly. Test equipment required for alignment is about what you would expect. In addition to a dc voltmeter, receivers require a stable, accurate signal generator for the channel frequency and the 10.7 MHz if frequency.
Transmitters require an accurate power meter and a means of setting the frequency and deviation.
A service monitor is nice to have, but hams have made do with various pieces of less expensive equipment. Crystals are best ordered directly from us so we can make sure you get the proper type and with good commercial temperature stability and accuracy ratings. Crystals take about 3-4 weeks to make because there are many steps to the process and good crystals have to be artifically aged in temperature chambers to reduce aging drift after installation. If you have a repeater, the receiver and exciter each need different crystals. Be sure to tell us the channel frequency for each crystal and the model number of the module in which it will be used.
