In the Homebrew and Mods area because a bit of homebrewing and modding was required to get the thing to work.

That's Kool!
I can't make out the different models and what all is in there.
Can you tell us, please?

All of the equipment was made by Cubic Communications - Oceanside, CA. They're the company which bought Swan back in the late 70s.
The transceiver is an Astro-D: 1.5-30MHz coverage, synthesized. Incorporates a TCXO. Modes are SSB, CW, AME (LSB with exalted carrier). 100w PEP output.
Homebrewing and modding came into play where the synthesizer, noise reduction and filtering circuits are concerned - and the rig (one of three such models I currently own) will now transmit and receive true AM - though I'm not happy with the AGC implementation and may redesign that portion of the receiver.
Power supply is a PSU-8; autoranging input voltage between 90 and 250VAC; 50/60Hz. Has provisions for connecting and charging a separate gel-cell battery pack, of which I have two. (They also rode in suitcases).
Antenna tuner is an ST-5 - matches coax or random wires.
Underneath the flap at the top side of the case was supplied a coax-fed antenna, mic, power cabling, straight key, Telex headphones and assorted global power-plug adapters.
Cubic also offered rack-mount versions of the equipment, for both commercial and amateur markets. This is currently sitting in my basement shack - only 20 complete ensembles were built. In the middle is the Astro-DR; the rack-mount version of the -D. I've only ever seen one of these for sale, and an Island member tipped me to it.

Neat! The first rig I bought,when I got re-licensed as a Novice in 1992, was a used Swan 700CX.
I worked ZL from SC using a 10 meter mobile Hamstick with 2 radials on my 2nd floor balcony on SSB.

The first one (from 'IzE) looks scarier. Especially those "Tinkerbell" speakers. ;)
Bet it sounds like crap-o-la!
