Various Interfaces for computer control, digital modes,
etc. For Sale:

Kenwood IF-232c Interface / Converter

The IF-232c is the interface adapter for connection between
the RS-232C terminal of a personal computer and the interface
terminals of transceivers capable of computer control, such
as the TS-440S, TS-940S, the TS-811/711 series, and others.

The interface acts as a voltage converter between the RS-232C
port (-12 to + 12V) and the TTL levels of the transceiver
(0 to +5V), and as a noise-suppressor.

This one includes a wall wart power supply, DIN plug, and
paper work for $60.

Heath HD-15 phone patch / digital interface
This is the unit with the VU meter on the left and 3 knobs
that match the SB series to the middle and right.  Low or
high Z output to the transmitter. It can also be used as
an interface for PSK31, and other digital modes.
It is in excellent condition.  It has a couple of modifications
that are very professionally done.  The actual meter movement
has been replaced with a slightly larger, and more professional
looking meter.  Knobs are original. There is a modular jack
added for the phone line.  Two RCA phono jacks have been added
for speaker in and out.  In both cases, they are in parallel
with the original terminal strip, so either may be used.
It works fine and looks close to new.  A terrific unit.
Paper work included for $30.

Heath HD-15 Phone Patch
As above, but with no modifications, in extremely good condition.
No scratches or imperfections. Paper work included for $25.

Waters "Universal Hybrid Coupler II" Model 3002:

Most of us would likely call this a phone patch, but it
is really much more than that. It does that, but also
will interface with a tape recorder, and permit recording
and play back of on-the-air QSOs. Nothing says that the
tape recorder input must be used that way. Connect the
sound card in your computer in this position, and you
have a very effective interface.

Model 3002 includes a speech compressor powered by a 9
volt battery. The front panel is finished on both
sides, with one side having it set in a horizontal
position, and the other in a vertical position.

This was a "top of the line" unit years ago. One only
found them with top stations such as Collins.

This particular unit is in really great condition.

With paper work for $100.

Earthmate GPS by DeLorme, with software

The GPS unit plugs into a USB port on your computer.
DeLorme Street Atlas Software is included, so plan your
route, and also let the GPS tell you where you are, and
give you voice directions, if desired. You can even ask
it questions!

It will calculate your route and tell you exactly where
and when to turn, plus figure statistics such as mileage.

The GPS hardware unit is powered from the USB port, so no
additional power supply is needed.

This particular unit is in close to new condition, in its
original box, with the GPS unit, and the software. I would
think that it could be used with APRS. $65

Linear Amp Switching Cable for Kenwood Rigs:
This cable goes from a Kenwood transceiver to a linear
amplifier to switch the amp from transmit to receive. One
end has a DIN connector, as is used with most Kenwood rigs.
The other end has an RCA phono plug, as used by most linear
amplifiers. Before using this cable, please check the
switching capabilities of your transceiver.
This cable has one coax for switching the relay. $12
