NOTE ON REPLACEMENT PARTS:
If you lose or damage parts during assembly or testing, you may, of course,
order any needed replacement parts by writing or faxing the Ramsey
Electronics, Inc. factory. Some of the more common parts may also be
picked up at Radio Shack or other local parts distributors. Use EXACT
values when replacing parts. Following is a GENERAL guide to obtaining
parts for your transceiver as quickly as possible:
A Radio Shack or local electronic parts distributor:
Resistors, electrolytic capacitors, disc capacitors, common NPN or
PNP transistors, Zener diodes, switching diodes, voltage regulator
(5V), hookup wire, LED, controls, antenna connector, replacement
1-amp fuses.
B Order from RAMSEY ELECTRONICS:
Most RF and VHF transistors, coils, crystals, PIN diodes, varactor
diodes, trimmers, filters and most IC chips.
C U1 and U6 are Motorola devices
These parts might be in stock at service shops featuring Motorola
equipment. There are acceptable "standard replacements" for some
of the semiconductors used in the transceiver. "SK" and "ECG"
standard replacements are stocked by local electronics parts
distributors or may be ordered through a Radio Shack store. The
following chart should help you make the most cost-effective choice
if replacement semiconductors are needed:
