Pastime Projects Aluminum Chassis 6V6 6L6 CW Transmitter Kit Now Shipping

April 25, 2015

APRIL 24, 2015   The new aluminum chassis transmitter kit manufactured by Pastime Projects (www.pastimeprojects.com) is now shipping. This kit features a pre-punched aluminum chassis, a 15 page manual, tube sockets, variable capacitor, key jack, SO 239 chassis mount antenna connector, expanded metal bottom cover, chokes, capacitors, resistors, power and hookup wires, coil form with instructions, new tested 6V6/6L6 vacuum tube, power wire cable sleeving,  and hardware. The design is based on handbook designs of the 1960’s and allows band changing with coils and crystals. It has been tested on 160 and 80 meters and suitable coils will be released in the near future.

The 6V6 MC Model kit can be purchased from www.pastimeprojects.com.  See the web page for further details.

Pastime Projects 6V6 Transmitter Kit Features

April 1, 2015

The new 6V6 MC Transmitter being introduced by Pastime Projects is a single tube CW (code) transmitter for use in the HF Amateur Radio Bands. The initial offering will be for 40 Meter Band operation. It is a vacuum tube kit which the buyer assembles. A complete manual is provided for those with technical ability and experience to assemble and operate. The design is based on circuits commonly used in the 1960 era of amateur radio. Some features of this project are described on the home page of the Pastime Projects Home Page found at http://www.pastimeprojects.com.

If you are interested in purchasing one of these kit when they are released, you can get on the first come, first served list by contacting pastimeprojects(at)yahoo(dot)com.  73 Glenn for Pastime Projects

Summer at it’s best

July 26, 2013

Summer is in full swing here in mid ohio. We attended the radio hamfest in Van Wert Ohio and look forward to the Findlay hamfest later. Summer usually brings on lots of activities other than radio. We are working on stocking the new all metal chassis 6V6/6L6 little oscillator/transmitter kits. These have a bottom cover made of aluminum like the chassis itself, but with perforated holes for ventilation. We have measured power out at various plate voltages. The output ranges from about 2 watts at around 200 VDC to over 10 at 350 VDC through the link coupling which matches 50
ohms impedence. The link coupling keeps the kit simple and less expensive that a pi-network. Besides most modern radios use 50 ohms impedance output. My thinking is to supply the kit with a companion power supply that will provide the filament voltage of 6.3 VAC as well as 200 VDC for the plate.
This is plenty of power for some great CW contacts. Those more experienced would probably prefer to build their own power supplies anyhow. You can save a lot of money on used
transformers, chokes, and so on. Have your priced new transformers lately?
Enjoy your summer. Remember http://www.pastimeprojects.com when
cooler weather brings back ham radio building projects to the old work shop.. 73 ES BCNU! Glenn
