Mercury Wetted Relay The Hallicrafters HA-1 “TO Keyer” uses this relay as a main component in the keyer. Its an odd bird for sure – liquid mercury makes the contact in this relay. I was able to find replacement parts – but they are $120 or so NOS. Looking at the schematic – yeah, this […]

I will take the HA-1 “TO Keyer” apart today and test the tubes and make a list of what caps I will need to order to recap. While I was under the house getting the two bolts to add the fans to the MFJ-267, an attempt to deliver the KWS-1 happened – and I didn’t […]

The keyer, as expected – in great condition, however, I will recap it and also test the tubes. And, look what followed me home: The surprise? A Central Electronics MM-2 “Multiphase RF Analyzer” – which is a 3″ CRT based oscilloscope. This model has the capability of monitoring both the KWS-1 transmitters waveforms as well […]

The three microphones L-R are the Astatic D-104, probably the #1 mic that hams used with the KWS-1, the Shure 51B “Sonodyne” – used mostly by recording artists like Nat King Cole, Turner 99 – the oddball of the three, I don’t know what it was used for in its day. The three keys L-R […]

Mushrooms. No particular reason why I used this photo except it looks cool. My friend Tony, K4QE wrote a nice note to me regarding this blog, and it occurred to me that the Pursuit, the Journey and the Rewards are the best reasons to have a hobby. I like the word “Maker”, and I’m sure […]

This Bug has serial number 124407, which dates to 1943 – during a very busy WWII time I wanted a good representative version of a Vibroplex Bug – just so I could use it with the Collins KWS-1 (if I ever get it back – hi hi). There is a great PDF available on the […]

Hallicrafters 1959 Christmas Advertisement Hallicrafters seems to be one of the first “mega” advertisers. They had quite a bit of gear – many models – and obviously had a big advertising budget. I had OT Elmers who thought Hammarlund made better gear, and everyone knew that Collins was the best of the best. However, Hallicrafters seemed […]

The Hallicrafters TA-1 “TO Keyer” This tube based keyer was first sold in 1960 – which was about 5 years after the Gold Dust Twins were first released. I’ll have one next weekend – and it will be a lot of fun – especially because it has a monitor, and will be cool to hear […]

The Astatic D-104, 10-C and 10D – classics and used with the KWS-1 There are so many cool microphones, but I will cherry pick a couple decent one’s and also will pick a set of keys to use with the Collins KWS-1. Astatic D-104, Shure “Sonodyne” 51B, Turner 99 I replaced the old dried out […]

I am really enjoying this renovation bug!  I have already renovated two of my favourite receivers from the past, the HRO receiver and R1155 receiver. Both are working well and I am quite proud to have these old classics back to life again. My next project takes me back to 1971 when I bought a […]

I joined the CCA after a few very nice and helpful hams who have Collins gear highly recommended that I join. I have already found it to be a wonderful group of friendly people – who genuinely are excited that I am now “in the fold”. Interconnections between the 75A-4 and KWS-1 All of the […]
