Rebuilding a Life, Rebuilding a Shack- it is all Drama

Well I got all of my vintage radios out of storage where they have been for about 2 years and have now got them all set up in my tiny apartment, though no suitable antenna yet.  I also managed to bring along all of my test equipment and various cables and audio mixer etc etc.

The problem is of course, when you leave stuff for so long, especially stuff that was the subject of restoration and many little and large projects, you kind of forget where you left off. I recalled as I began to test equipment with my meagre antenna and dummy load, that not all was 100% when I left it. The Yaesu FT101E was, but now isn’t- that is pretty normal for an FT101 left in storage, so no surprise there. I was disappointing when I connected the mains chord to it and blew resistor 1 on the rectifier board, because that was not my chord but one I had purchased and it was probably wired incorrectly – ouch!

More interesting when I remember that the plan of using the Johnson Viking Ranger II and the Hammarlund HQ170 as a transmit/receive pair had fallen on issues as well- issues I had forgotten. See the HQ170 receiver pulls wildly off frequency when I transmit on the Viking II and sounds very chirpy. I am convinced it is the way this radio uses AVC(automated volume control not AGC) – although switching off the AVC makes no difference. So now I recall that I had a huge project to do with the Hammarlund and had kind of decided to ditch it and get something vintage but more stable. That is out of the question now because I am nowhere near as financial as I was when I had my own business. Wonder what I can do to stabilise it? My fist attempt will be to replace the OB2 valve (tube in the US) with a solid state version.

The Viking Ranger II I was sure had no issues. I remember using it on CW and AM and it sounded great on AM, but then did I not change the value of a capacitor in the audio circuit in order to improve performance and some how stuffed that up? Or was it that an audio amplifier tube was to blame? Either way there is nasty hum and no audio from the microphone on AM today when I went to use it on AM. Since I can’t remember what I did two or more years ago, I will have to go through the service and construction manual and backtrack.

Maybe these radios will be working properly two years from now. You can follow the saga here http://antiqueradios.com/forums/viewtopic.php?f=5&t=314753

    My first receiver I listened to the ham radio in the mid 60s was the old BC 312. Quite good receiver. Later, when modern RIGs appeared on the market, I lost it. Now I am trying very hard to find another BC 312 or BC 348. I like WWII military equipment.
