HIKER'S AM BCDST/SHORTWAVE 49 TUBE REGENERATIVE RECEIVER

Description: I HAVE UPDATED AND IMPROVED THE CONFIGURATION OF THE BATTERY POWER SUPPLY, BUT THE RADIO YOU'LL RECEIVE WILL LOOK VERY SIMILAR TO THE ONE SHOWN. THESE ARE MADE TO ORDER SO PLEASE EXPECT ABOUT 10 TO SHIP, ONCE PURCHASED. POPULARIZED BY THE HIKER'S SERIES OF THE 1930'S, FEW VACUUM TUBES EPITOMIZE THE OLD WORLD OF THE REGENERATIVE RADIO ART MORE THAN THE DUAL GRID 49 TUBE. IT HAS A 2 VOLT FILAMENT, RATED AT 120 MILLIAMPS. THERE'S AT LEAST A DOZEN VERSIONS OF THIS RADIO SCATTERED ABOUT IN PUBLICATIONS OF THAT ERA, AND THE 49 TUBE REGEN RECEIVERS REMAIN POPULAR TO RADIO ENTHUSIASTS, EVEN TODAY. THE 49 MAKES A WONDERFUL DETECTOR, WITH CRISP, CLEAR AUDIO. THE SPECTRUM COVERAGE IS CONTINUOUS FROM ABOUT 540 KHZ IN THE AM BROADCAST BAND, UP TO ABOUT 14.5 MHZ SHORTWAVE, USING THE PLUG-IN COILS PROVIDED (SIMILAR TO THOSE IN THE PHOTOS). I MOUNTED THIS RADIO ON WOOD CRAFT BOX, WHICH WOULD HAVE BEEN TYPICAL OF THE FARM RADIOS OF THE 30'S AND 40'S. THE WOOD FRAME HAS SEVERAL COATS OF URETHANE FINISH. THE LAST PHOTO SHOWS THIS SAME RADIO IN A SLAT-BOARD CONFIGURATION, WHICH WAS ALSO POPLAR IN THE 1930/40's ERA. FEEL FREE TO REQUEST EITHER CHASSIS STYLE, SAME PRICE. AS A BONUS I HAVE ADDED A ONE STAGE TRANSISTOR HEADPHONE AMPLIFIER, WHICH INCREASES THE VOLUME CONSIDERABLY. THE TRANSISTOR AMP IS PART OF THE CIRCUITRY, AND RUNS OFF THE COMMON DC BATTERY B+ LINE. WITH THE RECOMMENDED LITHIUM-ION RECHARGEABLE BATTERIES INSTALLED, YOU DO NOT NEED ANY ADDITIONAL EXTERNAL SUPPLY VOLTAGE. BATTERIES USED ARE 2X OF THE 18650 AND STANDARD 9 VOLT TYPE. THESE ARE ALL RECHARGEABLE TYPES (NO BATTERIES ARE INCLUDED IN THIS LISTING). IN LATER VERSIONS I SWITCHED TO A SINGLE HIGH CAPACITY 26650 BATTERY FOR THE FILAMENT SOURCE (SEE LAST PHOTO). THE MAIN TUNING CAPACITOR AND/OR DIAL APPEARANCE MAY VARY SLIGHTLY, DEPENDING ON WHAT I HAVE IN STOCK, BUT WILL ALWAYS LOOK SIMILAR TO WHAT YOU SEE IN THE PHOTOS. YOU WILL ALSO RECEIVE A HIGH IMPEDANCE PIEZO HEADSET, USING DUAL PIEZO ELEMENT INSERTS. I MAKE THESE WITH NEW PARTS AT TIME OF ORDER (SEE PHOTO). THIS RADIO HAS MAIN AND FINE TUNING, REGEN AND ANTENNA COUPLING CONTROLS ON THE FRONT PANEL. YOU'LL NEED A WIRE ANTENNA OF AT LEAST 25 TO 50FT IN LENGTH, ALONG WITH A GOOD EARTH GROUND. A 75 TO 100 LENGTH ANTENNA WILL PERFORM BEST ON THE LOWER FREQUENCIES. AS STATED, AN ANTENNA COUPLING CONTROL IS PROVIDED FOR ADJUSTING TO DIFFERENT ANTENNA LENGTHS. I GUARANTEE THIS RADIO WILL WORK IF YOU HOOK IT UP PROPERLY. I'M NOT VERY GIFTED AT DRAWING, BUT WILL INCLUDE A HAND SKETCHED SCHEMATIC DIAGRAM OF THE CIRCUIT, PLUS A BLOCK DIAGRAM SHOWING WHERE TO HOOK THE ANTENNA, HEADPHONES, POWER, ETC.
