RADIO CONVERTER sa CB RADIO CONVERTER sa FM RADIO CONVERTER sa SHORTWAVE RADIO CONVERTER x CONVERTER (RADIO) xx RADIO How to use a low-cost, AM, BC-band transistor radio as the foundation for an amateur-band receiver. Various circuits presented to adapt these receivers for CW/SSB reception. Tune CW or SSB on any radio with $3 Universal BFO. One-transistor shortwave converter turns any broadcast radio into a shortwave receiver tuning from 5 to 15 mc. Powered by 9-volt battery. Two-meter converter for use with a broadcast band receiver. Receiver to pick up the time standard broadcasts from the National Bureau of Standards (WWV) and Dominion Observatory, Canada (CHV). One-transistor marine band converter for a broadcast radio. Also tunes 80-meter amateur band and WWV (at 5 mc). A one-transistor marine-band converter for a broadcast radio. Also tunes 80-meter amateur band and WWV (at 5mc). One-transistor converter tunes aircraft frequencies (108-136 mc). Est. cost: $4. Beat frequency oscillator (BFO) for any radio. Allows transistor radios with shortwave tuning to pick up SSB and code transmissions. Add CW and SSB reception to any radio with a 455-kHz IF transformer using this simple BFO circuit. One-tube low-frequency converter. Construction of a converter operating from 15 to 2,000 KHz for use with receivers tuned to 10 meters. Covers the range below 150 meters. Convert an old AC-DC table radio into a crystal controlled shortwave receiver for one frquency between 5 and 20 MHz. Est. cost: $5. VHF police frequency converter for AM radio. Est. cost: $20. RF band converter tunes from 30-50 MHz. Simplicity converter (SimCon) for an auto radio allows you to hear the emergency bands (25- to 55-MHz). Est. cost: $14. Tips on assembling the KCS converter kit from Carl Cordover & Co. Circuit for a BFO to pick up CW and SSB signals. Does not have to be attached, only placed near, a multiband transistor portable radio. Install a small trimmer capacitor on the exterior of an inexpensive "weather monitor" radio and you will be able to tune in fire, police and some FM programs. DX-Com. Crystal-controlled converter allows you to tune three shortwave-broadcast bands on your car radio. Est. cost: $15. Shortwave converter for AM receiver tunes 9- to 15-MHz band. Converter to tune in on new 460-mc police frequencies. GC-2 Deluxe, a general-coverage converter using two transistors that tunes from 200 KHz to 18 MHz. Convert your "All American 5" for 120-meter marine band. Changing the antenna and oscillator coils will give a tuning range of 1.7 to 5.5 MHz for AM receivers. Est. cost: $10. Convert just about any AM broadcast band radio into a 75- and 80-meter ham band receiver to pick up CW, SSB, and AM phone signals. No physical connection between converter and the AM radio. Est. cost: $14. Get more VHF on AM/FM transistor radios. Adapt a radio to listen to police, fire, taxi, airport and 2-meter ham calls, as well as AM/FM. AM radio converter to receive the National Bureau of Standards station (WWV) or the Canadian equivalent (CHV), both of which give the exact time every few minutes. Shortwave converter for AM broadcast receiver. Tunes 14-31 MHz. Est. cost: $7. VHF frequency converter for an auto radio covers 25- to 225-MHz service bands (police, fire, civil defense, etc.) Est. cost: $40. A simple shortwave converter for a portable transistor radio. A low-cost emergency broadcast system monitor. Add-on circuit monitors the output of a broadcast receiver and sounds an alarm when an EBS warning signal is received. Estimated cost: $25. A simple shortwave converter for any AM radio. High-performance shortwave converter for an AM car radio results in a portable SW receiver with good signal selectivity. Conversion puts AM radio on marine band. Est. cost: $5 Converter allows you to tune in aircraft frequencies on AM radio. How to install an FM converter on your AM car radio. Convert a pocket transistor radio to receive any one of the 100 FAA weather report stations by simply adding two capacitors across the tuner. Circuit for a crystal-controlled converter which will allow you to listen to shortwave broadcasts on an ordinary AM radio. Build this low-band converter to tune from 3 to 300 kHz. Convert your AM radio to receive C-QUAM stereo broadcasts. Est. cost: $25. New life for old car radios. How to convert a car radio into a high-quality receiver for your home. Part 2. Build a shortwave converter. Low-frequency converter is combined with a standard AM radio to hear traffic in the frequency range of 10 kHz to 550 kHz. One-band shortwave converter for a car radio. Covers any 1-MHz segment between 5-30 MHz depending on components selected. Dipperette-1, a mixer circuit. When used with a grid dip oscillator as the local oscillator, it is a shortwave converter that will tune in a healthy SW signal via any standard AM radio. Est. cost: $4 (less power supply). A 6-meter converter for a standard broadcast band receiver. Tunes 50 to 51.8 MHz. Uses one compactron tube. Converter to tune 158.88 MHz on a standard automobile radio. VHF converter to hear aircraft communications in the 118-128 MHz range. Est. cost: $7. VHF converter for an AM radio to pick up police and fire calls. Est. cost: $6. Two meter ham band converter for BCB receiver. | |||||||||
