Ten-Tec PM3A QRP rig 40 & 20 meters
Includes manual with servicing info . . . $125US
Price includes shipping to Canada or US (lower 48 states)
The rig is in very good condition for it's age. All the labeling is good.
There are some scratches. The worst one is from a previous owner, who's
drill slipped when he was drilling a hole for a mini head phone jack.
Nothing major, depends on what angle you look at the rig and does not affect
the way it works. It was recently checked out by a ham who runs a local
service shop. He told me it is perfect working order
and was surprised by the sensitivity of the receiver.
QRP CW Transceiver, 5w on 40 and 20m (with full band coverage).
Synchronous direct conversion receiver with dual-gate MOSFET
(receives CW, SSB and AM), slide-rule dial, sidetone and
break in keying.
POWER-MITE - PM3A
The power-Mite 3 and 3A are self-contained CW transceivers
ing 40 and 20 meters. The receiver is comprised of a variable
lator operating on the received frequency, a mixer and high
amplifier. The received signal is converted directly to audio
filter eliminates undesirable signals, and then amplified to
level by a high gain audio amplifier. The variable oscillator
7.0 - 7.3 MHz for 40 meter operation and is doubled to 14.0 to
MHz to cover 20 meters.
The transmitter driven from the same oscillator-multiplier
for receiving, has an isolation stage, driver and push-pull
amplifier. It is keyed in the buffer stage. The output
a Pi network to match 50-75 ohm unbalanced loads. A side-tone
lator with variable frequency and volume is keyed long with
