The tube checker you have is one from about 1960 or so and was made for them by EMC, maybe as a kit or by Mercury. They were also...

    Can you test tubes with an ohmmeter for more than shorts?

    I bought an Eico 350 tube tester about 15 years ago.... The only good way to check vacuum tubes or also known as valves. The tester will load the tube properly with correct voltages and measure resistances and drops. The only good way to check a tube! If a tube has a dull white spot or spots...

    The 2510 is a wide transceiver and I would check for a variance across the bands, but! 1.8 SWR is not bad at all! 73 mechanic

    The MOD

    I've started with Arduino and with the IDE and a good plan it should work. The Atmel processor should be able to most anything..... If done right an old Commodore 64 should do a few things. 73 mechanic

    The MOD

    I'm sure many of you remember the "MOD" where 'weakstation' came up with a control circuit using EPROMs to control the PLL and VCO. Lots of channels for different MB8719 chassis. Pretty much forgot about this till today as I was doing a search for my old Geocities page. The front page is...

    radio 'sondes' on VHF and UHF

    My operations on two meters SSB with locals is decent and living in the Great Lakes area only seems to enhance this. Many times talking with locals and my yagi pointed East I have been hearing radio propagation 'pips' or 'twits' on 144.200 USB. They for all the World sound like what is heard on...
