While surfing the internet in 2011, I visited www.2dehands.nl/zendamateur
The transceiver section showed a transceiver that was very familiair to me:
The 145 MHz FM transceiver Model 2030 from Uniden (made in Japan). This set is
designed for mobile use and offers 12 channels in the 2 meter band making
transmissions with 10 Watts RF possible.
With a similar 2m set (Zodiac Gemini) and a Ferranti 2m Yagi I made my first 2m FM
QSOs in 1980/1981 when I still lived in de Betuwe (Culemborg). At that time I had
a limited D-licence; you were only allowed to work on 6 frequencies in FM in
the 2m band. Since the price of the used set was acceptable I immediately ordered
After being delivered by TNT-post, incl. 'operation manual 'I connected the Uniden 2030
to a simple GP antenna. After some CQ's on 145.500 MHz, PA65L from Leiden responded.
Everything worked fine !
No frequency synthesizers or PLL in this rig, but 12 discrete Xtal positions. That's how
it was done in the late 70's.
Crystal positions are as follows:
1) 145.250 MHz
3) 145.500 MHz
6) 145.400 MHz
7) 145.175 MHz
8) 145.000 MHz
9) 145.100 MHz
10) 145.050 MHz
11) 145.200 MHz
12) 145.075 MHz
The Uniden has a switch to set the output power; you can select 1 or 10 Watts.
The transistor producing 10 Watts is a 2SC1605A. An 'automatic protection circuit'
assures that the PA is switched off when the SWR becomes too high.
