The W3HM Collins Gold Dust Twins T-R Switch

The custom made W3HM T-R switch and wiring harness that makes the Gold Dust Twins “plug and play”

While I could have built this myself, I am very glad that I purchased this made by Howard, W3HM. It handles all of the interconnections between the KWS-1 and 75A-4, and besides being perfect as far as how it “packages” all of the connections that I need – it also looks beautiful. At first I thought it was a bit excessive that he wanted to powder coat it – but the minute I opened the box I knew why he insisted on it.

I had a small scare in that it didn’t seem to work. I opened it up and found that the relay – that has a socket had been jarred loose. I plugged it in and it works like a champ.

I’ve now turned the KWS-1 on several times and double checked the Power Supply restore that I did – and so far, so good. Today I will put the MFJ-267 Dummy Load / Wattmeter in line and practice tuning up. I hope to get it right on 40M and have my first SSB QSO with the rig. I will have the Speed-X bug and D-104 set up for this tuning and first QSO.
