1. Is there wire with camoflage insulation? (just kidding!) I plan on using wire with beige or tan colored insulation. I think sky blue or grey would provide the wrong contract. Any ideas on this? Dunno.. From what I notice, lighter colors may blend with the sky at times, but they also reflect light more, which can cause the wire to stand out more at certain times of the day. 2. The far end of the antenna will be hanging from and in the branches of a tree. I will only be running 5W (if I'm lucky) and wonder about the voltage at the end of the wire. Will some heat shrink provide suitable insulation to prevent corona from starting the bush on fire? Is there a better idea? I will be using PTFE (Teflon) insulated wire. No problem with that.. 5 watts is not enough power to start anything on fire.. Even 100w will have trouble doing that in most cases. Only when I was running high power have I noticed arcing and burning of tree branches touching the ends of antennas. You can use almost anything as an insulator and should have no problems with QRP. 3. I'll be running the wire from inside my suite through a 1/4 inch hole in the aluminum window frame. I was going to feed it through a plastic straw to prevent chafing and possible short circuiting. Any suggestions on the best way through the hole to prevent any problems? I suppose that would work ok.. or maybe run and melt some thin heat shrink tubing at that point.. 4. Is there a way to tell if the glass in my windows has some property that greatly attenuates signals? I'd ask the management but I don't want to trigger them into realization that future QRM will probably be emanating from my 'shack'! I plan to work the world while remaining invisible to those around me. If asked, I'll just explain that the wire is an antenna for my short wave receiver!!!! Glass is fairly RF invisible I think.. Should be no issue. This is the first time I've had to use a store bought rig! Until now I've either had modified surplus or burned out rigs which I rebuilt. I've always been an advocate of low power, but real QRP is new to me too -- and I equate it to the difference between dynamiting ponds and fly fishing! Time will tell! :-) When I became ill I gave away all my 50+ years accumulation of valuable ham radio equipment, tools, test equipment, and books -- collectively A.K.A. "Junk". It's fun starting from scratch -- at least my shack is not a terrible mess -- YET! Low power can do fine if the antenna is decent. Do folks still mail QSL cards? Or can I settle for emailing a graphic equivalent of my own design? I've been off the air for a couple years now and think that things may have changed while I was out of the picture. This is not a big problem as printing and using the local buro shouldn't be too much of a problem. The hundreds of rare QSL's coming into my mailbox my invite unanticipated curiosity from the management. I don't do QSL cards myself.. In fact, I've never sent anyone a QSL card ever.. And I don't need any to send me one, but of course still many do.. The CW contacts are much more likely to generate QSL cards than the typical phone jabber.. The way I look at it, is I know I worked the people.. I don't need paper proof of it.. :/ Maybe you could get a PO box, and assign it as your new mail address, and have someone check the mail every once in a while. |
