Some fellow ARF Antique Radio Forum members offered to send me some parts to get started on a quite successful 6888-based AM transmitter.
2 TUBE RADIO PLANS. Power for this receiver is 15 V DC for the filaments and 45V DC for the plate current. This greatly improved the regenerative qualities of this radio. Connect together pins 2 and 5 and attach that common lead to C8.
1942 One Tube Beginners Special Receiver. Simple FET Regenerative Receiver. -With a ruler mark the tube at 5 inches from on end and wrap tape around the tube at that mark-With a sharp knife cut along the edge of the tape to make a nice even cut.
The 6888 is an oddball octal tube that goes by the description of dual. Buy the Catahoula Technologies Two Tube AM Radio Transmitter PCB. Testing and Operating the Receiver Set the VOLUME and REGEN controls to midrange plug in the.
I added two rf chokes. A third is to place the 1st grid at B potential thereby providing a nearby pull on the electrons from the cathode. Builders of this radio have reported distances over 1500 miles when conditions are right.
This radio kit will cover the AM radio band along with the SW radio band. The second grid screen is used as the control grid and the B charged plate gathers up the electrons. If you compare the two circuits you can see what I have done.
One in the plate circuit of the first tube. 2 A Push-Pull Self-excited Oscillator Transmitter of early design. This only cut the gain.
To wind the coil you well need. The Armstrong One Tube Radio covers the Standard AM. Broadcast Band from 550 KHZ to 1700KHZ.
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. One Tube 2xReflexed Superheterodyne Receiver. Information Donated In Part By The Following Persons.

No shame in that unless you let them convince you otherwise. Seventy-five years ago this month the July 1942 issue of Popular Mechanics carried the plans for this simple one-tube regenerative receiver. If you intend to use a small speaker connect it between pins 1 and 3.
Ground pin 1 of the jack. Requires two T-1T4_DF91 tubes not included. 1 The classic Hartley single-tube transmitter.
Youllneed to supply your own batteries. Not a multi-section tube but just a single active device that can drive a speaker on DX. The kit comeswith a ten page pamphlet.
A D cell and five 9V transistor batteries wired in series will work to power this radio. Rear View of the Hatry. A 2000 ohm headset or an audio amplifier is required.
Two-tube high-quality simple and reliable stereo low frequency amplifier for headphones with separate volume control and output to 35mm or 635mm Jack. Its powerful circuit pulls in amazing BCB DX from hundreds of miles away. Power for this receiver is 15 V DC for the filaments and 45V DC for the plate current.
My shack consists of a Kenwood TS-520S 1970s or 80s vintage an old Drake 2-B tube receiver from the 1960s which I use as a backup receiver a kit-built Ramsey 2-meter FM transceiver and various other boat-anchors and pieces of junk. This is not a loud radio so all the help it can get is welcomed. 3 The Original Frank Jones 10 watt Push-Pull Crystal Controlled Beginners Transmitter from his book The Radio Amateur Newcomer first printed in 1935 or so.
One builder reported that The Performance is AWESOME. - 2 diameter tube - 14 lb of 20 gauge enameled copper wire - ruler - pencil - small drill - pliers - wire cutters 1 Mark and cut the tube to length. Since it is a grid many of the electrons reaching the 1stgrid zip right on through.
Runs with only a 9 volt and a 15 volt battery. It uses 7 tubes and tunes from 28 to 165 Mcs. A BCB version of the Hikers Two.
The set was designed with wartime parts shortages in mind and most parts were non-critical and could be found in most junk boxes. Version 2 August 2008 Interested in building a two tube AM radio transmitter very similar to this version. A D cell and five 9V transistor batteries wired in series will work to power this radio.
Many articles have multiple plans. Based on a 6ME8.
