- 100 Watts adjustable power on all amateur bands 160-6 meters (25 Watts on AM)
- Automatic antenna tuner
- dual VFOs
- 127 tunable memories
- Integrated digital voice recorder
- Independent key jacks on the front and rear panel
- High performance DSP filters for razor sharp selectivity
- Automatic seeking notch filter and noise reduction circuitry
- Two main RX/TX jacks plus a separate receive only antenna jack
- Independent tuning knobs and digital dials for the two VFOs
- Alphanumeric display provides labels for memory channels
- Digital speech processor
- Built in RS-232C level converter and DB-9 serial port on rear panel
The Yaesu FT-920 is packed with high tech features such as: a high performance
DSP for razor-sharp selectivity, increased average power output and voice pattern
contour choice, automatic seeking DSP notch and noise reduction, built-in
antenna tuner for RX and TX, DSP bandwidth controls and shuttle jog tuning controls.
It provides exceptional multimode performance from 160 through 6 meters.
The 100 watt MOS FET amplifier and unibody construction provides efficient, full power
for ham bands 1.8 to 54 MHz. Utilizing rugged MRF355 FETs in a push-pull configuration,
the FT-920's final amplifier stage produces 100 watts of clean output power.
The multi-function tuning dials provide easy setup for split-frequency operating situations.
When seconds count, you will appreciate the ease of tuning with two large tuning knobs
in combination with the LED-illuminated VFO selector switches. The Sub VFO dial may
also be used for Clarifier (RIT/XIT) tuning or memory channel selection. Variable
tuning steps of 1 Hz, 10 Hz, or 100 Hz are provided on SSB, CW and digital modes
(10, 100 and 1000 Hz on AM/FM). An ergonomic keypad is available for band selection
or direct frequency entry.
For contesters, this transceiver even features a digital voice recorder and electronic
memory message keyer (4 messages of up to 50 characters each). A DB-9 RS-232C jack
is featured for an easy connection to a personal computer.
Includes MH-31B8 hand microphone, DC cord and manual. Requires 12 VDC at 22 amps.
It also has the optional AM filter and FM board options installed.
Check the reviews. This is a great rig with many extra features...
I am including the stock mic, along with the original box, manual, etc.
The rig is in excellent shape - a 9.9 cosmetically and a 10 operationally.
Used in a non smoking environment. Will sell for $800.00 firm + Shipping.

SX24 in Excellent condition. Available for $135.00 plus shipping
Here is a dual in-line package crystal oscillator that will generate RF on popular frequency
of 3.686 MHz in the 80m amateur band. Add your 5 volt DC supply at about 20-50 mA, a key and
an anetnna and you will be on the air with QRPp power and absolute minimum parts count!
Construction plans are available on line... see below.
Crystal stability means you will have no drift, chirp or yoop with this tiny silver rig.
Even use it as a driver for a more powerful RF final. Strictly speaking, you should add
a PI network or other matching circuit between the output pin and antenna for correct
antenna matching and to attenuate the harmonics, but I doubt that you would cause much QRM
with this multi-milliwatter package. Has approx. 10 to 20 mW output. Add a few parts like the one
shown above (Jersey Fireball, kit no longer offered) and you will have a fine little QRP rig.
You will not be the first to have made real CW contacts with a few milliwatts of power!
An experimenter's delight for the ham bands with four pins - ground, +5V and output etc.
PIN CONNECTIONS:
#1 No Connection
#7 Case Ground
#8 Output
#14 + 5 Volts supply
Dimensions in mm:
Plenty available now for $1.00 each or TEN for just $6.00 plus shipping!
N.B. This is just for the oscillator parts - the other parts, case etc. are up to you.
SCHEMATICS:
Here is a little Beacon transmitter using a similar 4-pin oscillator.
Here is a similar 160m design with a push-pull RF
final that could easily be adapted.
5 Watt version - similarly adapting the TTL signal from NAND gates with added boots.
Here is the JERSEY FIREBALL - a multiband TTL oscillator rig with a nice matching circuit you can copy, as shown above.
