PASTIME PROJECTS Transmitter Kits and Accessories Page |
This kit is based on Our (Glenn Brown Author) article in May 2006 CQ Magazine entitled "Look Ma - No High Voltage" It is a milliwatt range vacuum oscillator kit assembled breadboard style using a new old stock 12K5 vacuum tube that uses 12 volts dc on both the filaments and the plate. Great safe way to learn about vacuum tube operation. Also included is a 16 page manual written by the author, a pre-wound 40 meter coil, a spare plastic coil form and a new 7 mHz crystal which can be soldered across the crystal socket provided in the kit. The power output, unfortunately, will probably not be useful for ham communications outside of the shack. This kit is still a great way to learn some of the basics of a vacuum tube crystal controlled circuit. Perfect for code practice across the ham shack to your 40 meter receiver. The assembly manual is similar to the manuals that came with the radio kits in the 1960's. Plenty of illustrations and step by step instructions. One of the first products from Pastime Projects. $46.00 PLUS SHIPPING |
This is a carefully planned and designed replica of a late 1940's design code (CW) 'home brew' transmitter. This kit includes Amish prepared oak slats and end blocks. You assemble with supplied instructions and brass plated flat head screws. The kit includes terminal strips, solder lugs, tube sockets, wire, newly manufactured variable capacitor, resistors and tested NOS or import 6V6 or 6L6 vacuum tube, and a very detailed step by step manual. Will operate on 80 or 40 meters by changing the hand wound coils. Uses FT 243 type crystals. 2 to 10 watts out depending on the power supply. $58.00 |

This kit has been written up in QST magazine, and is subject of many posts on popular web sites. The design originated in the late 1940's and was published by the ARRL (American Radio Relay League) in many magazines and handbooks. It was originally a "do it yourself" design with very little instructions. It used "Orange Crate" wood for the chassis, brass screws, sucker sticks for holding the coil in place, and a coil that is wound around 8 penny nails laid out in a circle. Our design includes Amish prepared oak strips and end pieces, brass screws, "sucker sticks", and the nails to construct your coils just like the original. Many of the components are new (and we think more reliable than originals) but the retro look remains. This kit will operate on 80 meter or 40 meter CW ham radio frequencies with power out in the 2 to 5 watt (or more) range. It is crystal controlled. Change from one band to the other requires different coils be soldered in. The 40 meter version seems most popular amoung our builders.. The manual that comes with this kit contains step by step instructions for assembly, wiring, and soldering. The included vacuum tube will be a new import which has been retested here and certified. The builder will need a crystal and power supply. To put this kit on the air a license, antenna, and power supply will be required. The builder should be familiar with working around high voltage before applying power to this kit. A paper on high voltage dangers and safety practices is included with each kit.The radio is shipped in a sturdy commercial box and the packaging has been tested over many years to assure safe delivery.. |
