Olson Electronics was a company based out of Ohio and has many stores from New York to California. They were on the same level as Allied Electronics and Radio Shack. 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...

Photo chop this..... Blend with this....... 73 mechanic

Wow~! The knobs on that rig are the same on the Hygain 623 Utopia!

Most know about Rig Pics.... I found another based out of the UK! Radio Pics Database, here is the URL.... http://www.radiopics.com/CB%20Radio/USA%20CB/USA%20CB.htm This link is for CB and 10 meters radios.... Nice pics too! Some of these I have not seen before.... 73 mechanic

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

Found some info on the Micromonitor..... http://www.cbtricks.com/pub/secret_cb/vol_15/graphics/secret_cb_vol_15_pg05_06.pdf Interesting stuff! I'm digging deeper! 73 mechanic

Basically the channel knob, in a 23 channel crystal CB, controls the frequency by connecting the correct crystals to mix to make the wanted channel. Same thing for a PLL synthesized 40 channel CB. Sort of connecting the right "dots" to have the wanted channel. This can be done by a...

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

Nice job! looks good! Now you have kicked me to where I should start on my three Hygain 623 Utopias!

It is still there but not very active..... https://groups.yahoo.com/neo/groups/the_mod/info 73 mechanic

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...

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...

I always ran mine at 18 to 20 watts SSB and about 5 on AM lasts longer that way! What's FM? 73 mechanic

Ranger AR-3500 Not really an 'Oddball' but not exactly your common radio.... I have three where one works pretty good and the other two need work. Actually an ad but gives the then new price in 1988 dollars! Today? mechanic

Thought I would start a thread about one off or rare radios, so here is the first.... I do not know much about this base, I have a Cobra 135 GTL and looks to be the same size. Cobra must have used this on the early 2000 GTL before the chrome face came out. mechanic

This has been out for a while now in mainly Brazil, sometimes on Ebay. Looks to be a spin off of the Anytone AT-6666, 10 bands accessible by pushing the channel knob. Equals 400 channels. No idea of the price. In Brazilian Portuguese

I bought a Tram 2 meter and 70 cm antenna via Walmart.... I had my doubts about the thickness of the fibreglass tubing but so far has held up fine, two years. My Solarcon is pretty old now but was a thicker build where as the newer designs are far thinner and flex much more! Pretty sure the...
