Arrangement uses constant-current source Q2 to maintain stable bias voltage on base of Q3. By choosing proper resistor values, DC voltage feedback from emit- ter of bipolar is made to control constant-cur- rent value. With the main setting configured, you may wish to set up the radio features. Features such as nuisance channel delete and repeater talkaround make the radio a versatile, high-performance device. This particular version uses the UHF bands, and is a type 1, which covers 450 — 470 MHz. While this is not so good for the amateur 70 cm band, it is nearly ideal for use as a GMRS/FRS radio.

Lower pair of LM324 quad opamp sections function as full-wave precision linear peak detector. Other sites may now or soon provide a better resource for comparable data.-Jim Robbins, 11/25/16For all the municipalities or groups listed above, there is a table of the frequencies and a brief description of how they are used. For small signals, Tr, and Tr 4 can be regarded as long-tailed pair without tail. The SM-6000 series mobiles are the premier radios in the tough-tested Maxon Enduro product line.
