All Band Inexpensive 40 Watt Transmitter

 Jay Miller KK5IM recently wrote an article in Electric Radio magazine about fulfilling his dream of building a homebrew "AM Kilowatt" transmitter (375 watts output by today's standards).     His crystal-controlled exciter that drive the 813 was based on his Novice transmitter, which was built by his grand-uncle back in the 1960s when Novice class hams were l...  READ MORE

Lysco "Transmaster" Mobile Transmitter

 I'm always intrigued by the odd and unusual ham gear that I remember seeing in catalogs as a kid but have seldom seen after hundreds of hamfests and uncountable for sale listings.   One such is the Lysco mobile transmitter which was produced by the Lysco Manufacturing Company of 1401 Clinton St. Hoboken NJ between 1949 and 1953.   Despite being a very cute and co...  READ MORE

My $18.50 homebrew boatanchor receiver

Ad-Hoc Hybrid transceiver with 3-400Z finals?

 The  Dentron MLX-MINII thought it would be cool to use the Dentron MLX-MINI on the Saturday Vintage Sideband Net but it's a little marginal since the rule is "no tubes, go home!".   However hybrid rigs are allowed, and Special Dispensation is given for rigs with Red LEDs.    So I thought the MLX was double-qualifed - even more so after I realized t...  READ MORE

Multi Elmac PS-500

Some pieces of vintage ham gear are not really unique, but are so rare as to almost never be seen.   The Multi Elmac PS-500 power supply is an example, it was sold as an AC power supply for the A54 and A54H transmitters in the mid-50s. There's nothing special about it - just a big transformer with 5 volt rectifier, 6.3 volt filament, and 500 volt secondaries.  Two nice chok...  READ MORE
