2 TUBE REGENERATIVE RADIO

The radio currently tunes 7-11MHz. Two tube regen with 30 tubes.

Two Tube Regenerative Homemade Radio.

2 TUBE REGENERATIVE RADIO. 12 Volt Vacuum Tube Regenerative Receiver uses 6BA6s in grounded grid configuration. So lets get started. The grid RC is 27pf may try less and 10M may try more.

Youllneed to supply your own batteries. Power consumed by the two voltage dividers is less than 1 of total power consumed. This is understandable as you can quickly gauge the difficulty of a project by a quick look at the schematic.

Two Tube Superheterodyne Receiver. By Dave-N2DS Wed Jun 04 2014 947 pm. Regenerative Two-Tube Receiver for 40 Meters on the air.

Low Voltage 12VDC Two Tube Regen Receiver Using Space Charge Technology by KB5BCQ. Requires two T-1T4_DF91 tubes not included. Solder lugs are included with the kit to make hookup easy and the connections will remain tarnish free for the life of the set virtually forever The labels are also provided.

I decided that if I was going to build a superhet it had to have an IF. The A should go to ground and the A- to the filament current control rheostat. The kit comeswith a ten page pamphlet.

Begin winding the wire over the cardstock and around the. Secondary winding 12 and capaci- tors C3 and C4 select the received sig- nal while tickler winding 13 provides regenerative feedback. This receiver uses a 2N4416 JFET orJ31 which provides a more sensitive detector than an MPF102.

They advertised in magazines such as Popular Science and Popular Electronics. Requires two T-1T4_DF91 tubes not included. Regenerative Two-Tube Receiver for.

They offered a number of low priced simple kits. These tubes have a 14 volt filament at 50 ma current draw. Little by little they are getting better.

This is a reproduction of a two tube regen offered in kit form by Western Radio of Kearney NB in the 1950s. 2 Walt Turanskys KW7WT 3 tube Regenerative Receiver. Cut a 7-14 strip across the 2 width then cut this piece at 7-34 again at 4 and finally at 3 see Figure 2.

Power for this receiver is 15 V DC for the filaments and 45V DC for the plate current. Here is another radio in the series of tube radios that I have been building in 2002. The basic paradigm of this design is to break up the traditional oscillating detector into a separated regenerative amplifier and detector circuit.

Two D and five 9 volt. I couldnt figure out an attribution for this link. Again this is to allow more tube substitution flexibility.

This radio kit will cover the AM radio band along with the SW radio band. A 2000 ohm headset or an audio amplifier is required. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How.

JFET REGEN RADIO RECEIVER A basic JFET regenerative detector radio receiver-found at Radio Frequency Experiment by BH1RBG The regenerative detector is noted for its great sensitivity. Power for this receiver is 15 V DC for the filaments and 45V DC for the plate current. This was my first attempt to build a superhet receiver.

This is the old 0-V-2 design. A D cell and five 9V transistor batteries wired in series will work to power this radio. Low B helps too.

A regenerative detector uses the principle of positive feedback of a weak input signal returned thru an amplifying stage in order to substantially increase. This radio kit will cover the AM radio band along with the SW radio band. So its more like a 4-tube radio.

This allows some isolation between the antenna and the regen stage and from detector to audio stages. It is a five band. Dave Schmarder N2DS.

The design is by David Newkirk WJ1Z and appears in the September 1992 QST and in the ARRL. I had searched the internet for some low tube count circuits and discovered Jack Bryants KE4ID one tube superhet. A fun project especially for someone starting out trying to figure out how their radio works.

The detector is a plate detector where RF is fed back to the Amplifier via a partially RF decoupled source normally bypassed all the way for RF when used. A 2000 ohm headset or an audio amplifier is required. These pieces are respectively the base front and rear assemblies of the chassis.

Make sure that the length of the cardstock is to the right of each set of pinholes. I liked the simplicity but his circuit lacked an IF gain stage. Place the ½ x 2 piece of cardstock on the coil form just to the right of the pinholes.

Use ceramic formssockets in the Regen section because of low loss promotes high Q and rigidity promotes stability. This is a two tube radio built with a pair of 1T4 tubes. A low voltage 2 tube regenerative receiver A nice schematic showing 6C6s being operated as space charge tubes.

Calling it a 2-tube receiver is a little misleading since the two tubes are dual section types tetrode and triode. The filament terminals have plus and minus terminals that should be observed. You might f ind teasr om ply hck w a couple pieces of scotch tape.

Listen to the simple home constructed radio handle CW SSB and Digital signals in the modern 7 MHz B. Proper connections and polarities improves the regenerative detector performance greatly. A D cell and five 9V transistor batteries wired in series will work to power this radio.

Instead of going through scores of my pages looking for the project that is right for you I have assembled the schematics all on 2 pages. Walt says that this receiver will hear everything his more modern SS rig will hear and it is a really classic design. Although V2 and V3 could be replaced by either two 1H4s or a single 1G6 I have not yet found a more modern equivalent for the 32.

R3C5 are a grid leak arrangement that together. Armstrong regenerative detector cir- cuit. Start with a 2 x 4 piece of 18 tempered hardwood.
