1253 kit
9 band short wave 'regenerative' receiver
AM / SSB / CW

 

The classic "first radio kit" is back better than ever! We've combined the very same audio output circuit of Ten-Tec transceivers with a modern FET design for classic regenerative SWL receiving plus one-button electronic band switching.

The result is an easy-to-build short wave radio that's fun and interesting for the whole family. No alignment required! Simply install all parts as directed, put together the high quality mechanical parts and start enjoying the magic of short wave radio. Explore 9 smooth tuning SWL and ham bands from 1.8 to 22 MHz at the push of a button! Receives AM, SSB, CW and all those other short wave sounds.

FEATURES:

  • Front panel enclosure RF gain, Volume, Regeneration, Tuning and Fine Tuning controls.
  • Generous audio from Signetics TDA2611A audio amp.
  • Built in speaker and stereo phone jack.
  • Electronic switching of 9 tuning ranges.
  • Rugged, rounded clamshell steel enclosure.
  • Simple clear linear logging scale for large tuning knob.
  • Requires 8 alkaline C cells or external 12V DC power source.

9 BANDS

Frequency bands are typical but may vary by +/- 5% due to manufacturing tolerances.  Note that the bands begin to overlap each other above 8MHz.  Rather than trying for continuous coverage, the goal was to make sure that the most popular bands are covered easily.

Band 1 1.760 - 1.990MHz
Band 2 3.300 - 4.150MHz
Band 3 5.500 - 6.900MHz
Band 4 6.800 - 8.500MHz
Band 5 8.500 - 11.000MHz
Band 6 10.100 - 13.200MHz
Band 7 12.500 - 16.000MHz
Band 8 14.700 - 18.500MHz
Band 9 18.500 - 21.500MHz

Estimated build time: 8 hours

Power requirement:
Operates from 8 x alkaline 'C' cells (not supplied) or external 12 to 15V DC at 250mA minimum, 500mA is recommended. The connector is wired centre positive. An optional power supply is available (PSU8600).

Options:

• PSU8600 optional 12V DC regulated power supply, 3-pin UK style main plug (RF low noise)
• DC8600 optional 12V DC lead fitted with cigar lighter plug
• PHONO-BNC optional aerial adapter, converts a PHONO/RCA plug to a BNC socket
