Transmitters and Transceivers
Vintage equipment covered here are in the Amateur Radio Bands and Citizen Bands. A transmitter can only send information and the operator needs a receiver to listen to the reply. The transceiver can transmit and receive in one unit and are therefore more complex and have larger power requirements. The vintage equipment here are mainly vacuum tube units and are made by Heathkit(TM), which provided Amateur Radio folks (HAMS) a lower cost alternative to operate the airways by allowing you to assemble, calibrate and test the equipment.
A Brief Description About Heathkit(TM):
Edward Bayard Heath founded the Heath Aeroplane Company. In 1926 produced the first airplane kit, the Parasol. He died in 1931 in an airplane test accident. Howard Anthony, purchased the Heath Company in 1935, decided to change the product line to electronic kits, probably due to the growing need for radio/TV servicing. With the huge glut of WW2 surplus parts Heathkit developed its first electronic kit an oscilloscope in 1946. In the 1950's Heathkit entered the Amateur Radio market by producing kit products that HAM operators can build and save money. This business continued into the 1980's along with their test and laboratory products. Heathkit introduced HI-FI in the late 1950's, Television in 1960's and Computers in the 1970's. Heathkit left the kit business in the early 1990's and then virtually disappeared. In 2014 under a new owner Heathkit has introduced their first new kit a regenerative multiband radio.

Power Supply for Heathkit Transceivers
There are many generations of this particular model from 1963 to 1983 (HP23, A-C and PS-23), Each version hand fewer accessories until they got the HP-23C and PS-23 which had the fewest, due to technology improvements in Heathkit's transceivers.
These were made for their vacuum tube HW and SB transceiver series. These units are basic solid state units with RLC filtering. This version provides +700, +300/+250 and -140 VDC and 6.3 VAC. After 1983 Heathkit Transmitters and Transceivers were all solid state units.
40 Channel CB 4 Watt all transistor AM transceiver with AM/FM Stereo radio. Controls are pretty close together. Digital readout for CB Channel. Made in Japan.
These were sold by NRI as an in home course to prepare for the FCC Novice license exam. They came in a kit or assembled. NRI was the oldest and largest in home electronics instruction company founded in 1906.This is a rare find as the program was never successful due to limited interest. It only lasted 1 year.
Outdoor applications for CB or HAM applications. 3 inch dia speaker moisture protected in solid metal enclosure. Sold with bracket or wall mount and with screw in or RCA phono speaker connections.
Newer Transceivers for Comparison
Military and amateur radio technological advances have shed their gains to consumer electronics. Solid state parts have made amateur radio compact and portable like your mobile phone and other hand held gadgets. Plus the need for high voltage conversion has been minimal. Shown here are some equipment that lead to many of the handheld stuff we have today.
A 5 Watt handheld rechargeable transceiver from around 2012. Designed for Amateur Radio and Industrial Applications where ruggedness is needed.
Additional Features: * 5 watts RF Output* 200 Memories* DTMF Keypad* Keypad frequency entry* Enhanced Paging and Code Squelch* Submersible to IPX7 Specifications* Backlit Keypad & LCD* Internet Key for Access to WIRES™
