![]() Welcome to the joys of modern energy efficient construction. The walls are full of aluminum foil backed insulation for both thermal and acoustic insulation. The windows are coated with Low-E Titanium Nitride IR reflective coatings (40 ohms per square), which also blocks RF. The roofing material is carbon doped (instead of asbestos) which absorbs RF. The foundation is concrete, which also absorbs RF. Meanwhile, the proliferation of microprocessors, switching power supplies, and BPL like devices, offers multiple sources of QRN. You had it easy at previous locations. I kind of fell behind in my knowledge of modern constuction. I lived in my house for 29-3/4 years and even though I did a lot of renos, the infrastruction remained basically the same. It is good though that they are getting smart on energy efficient construction and other things -- hopefully we will leave our kids and grandkids with a world pointed in the right direction. As per another sailor many years ago said, 'I have not yet begun to fight!' Fighting is easy. It's negotiation that drives me nuts. I'm on the air but not sure just how well I am getting out, I don't want to measure it, I don't even care to know since it is a whole different matter on QRP. The proof will be in the pudding -- I may have to wait for good band conditions, but the only valid means of measurement will be the number of QSO's and bands I can work. From those lovely boxes of variable caps and assorted inductors (some roller-inductors) and a cheap 2nd hand 50ua meter I am going to build up an artificial ground which is about as simple a circuit as one can get -- the L&C in series and make a sniffer out of the meter and a diode!. I should have it all going in the next day or two -- as soon as I can get a round tooit. Yes. I admit -- I'm a master of procrastination Well, on with the further adventures of getting on the air to the point of satisfaction. Is that a lot, I ask? Thanks on the tips re the MFJ diodes. I'm aware of them and can test and change them if need be. So far, so good! I guess it wouldn't hurt to have some on hand -- it's pretty inevitable that with the experimentation etc, that I'll be doing some or all will get blown before you can say poof! Do you think that if I were to ask the management here If I could have an aluminum ladder outside my second floor window -- just to easy my mind about the dangers of fire, they might agree?
