Here is a simple relative RF Ammeter. The design came out of the Jan 2009 QST.
For you Old School Readers (OSR) of my blog I’m sure you are sick of the Ham Stuff. I am not sure what to do about that, as I already have two blogs!!!
I haven’t been posting Frenchie Pictures because I don’t have a supply anymore!! Since we moved to Brooklyn, we never go to the dog park and I never really seem them. So.. for that, I am sad.
But, here is a picture of one of our kitties. Well, it isn’t our kitty, but we are cat sitting. Her name is Mocossa
I got the compulsion to setup a live stream from my radio. It is sitting at 7.040 right now, and you can hear it at N1JER’s live stream
This radio is located at the top of Sunset Park in Brooklyn, NY. It is a superhet with about a 400hz wide filter, into an inverted V about 30 feet up at the peak.
This link will almost certainly be dead in a few days, so if this post is more than a week old don’t be surprised if nothing works.
EDIT: I changed the server for this to conserve upstream bandwidth, and to make it so that my dynamic IP was no longer an issue. The stream may stay up for some time as it is fun.
My CW still leaves a lot to be desired so I like to hit the trainer for a few minutes before getting on the radio. I hit a high score on RufzXP and was doing well in Just Learn Morse Code. I figured I was going to kill it.
So I tune around 40m and did not hear much at all. There was a fairly long QSO happening on about 7.041mhz and I listened in for a bit, one signal was really strong, and the other was only copyable 1/3 of the time.
I went over to 7.0425 and sat for a few, then busted out my QRL? and with nothing heard fired off some CQ’s. Nothing. Ok, that is normal. So more CQs. Nothing. OK.. so lets tune around some more. Back to the QSO and I could tell they were getting ready to wrap it up. I had never tried to tail end a QSO before so after they said 73 and did their ‘dits’ I waited a few seconds then just did a 2×1 CQ call.
But, for some reason I was all off! Just didn’t feel right, and I rather than CQ I think I said “don’t call me because this will be a horror show”. Of course the stronger station came back (NM7B??) but I was so out of it I kind of threw my hands in the air.
I hear it happens to all the guys, but I never thought it would happen to me.
