The TVC-2 from PC Electronics is a 420-450 MHz downconverter used to view  fast-scan Amateur Television signals on a standard television set on VHF Channel 3.  It is varactor tuned to any frequency in the 420 - 450 MHz band.  It uses a low-noise MRF-901 RF stage for good performance.
The board is mounted in a small Bud box (includes cover, not shown) and includes a 2-ft length of 50-ohm RG-58 coax with connector for the UHF input, and 2-ft length of 75-ohm RG-59 coax with "F" connector for the VHF channel 3 output.
Includes printed data sheet with schematic and board layout. I haven't used this in many years since I got a cable-ready TV that receives 430 MHz ATV directly.

The TXA5 from PC Electronics is a low power fast-scan ATV transmitter/exciter for the 420 - 450 MHz amateur band.  It is crystal controlled on 439.25 MHz, and can be expanded to 2 channels with the addition of another crystal and switch.  It has 80mW RF output, and is designed to drive an external amplifier module like the PA-5 from PC Electronics.  Linearity can be adjusted to compensate for compression in the external amplifier.  I just tested it on an HP8524C service monitor and works perfectly.  This board does not have the 4.5 MHz subcarrier components loaded (for audio).
I cannot find the paperwork, but should be available from PC Electronics.
