- I wouldn't worry about it... Probably technically, you're not supposed to
- transmit until you get the new license in your hands, but who's gonna know?
- And who's gonna enforce it? But with only 90 days having passed, I wouldn't
- worry about the form being lost or anything like that. As I'm sure you've
- heard all around, the FCC isn't cranking them out too fast these days!
-
- As much as I relocate, I don't think I'll ever have to worry about renewing,
- since that's covered each time I change my address... :)

- Oh ok. This explains why the commercial signals are clear. I think this
- receiver is *supposed* to receive SSB, as each freq appears twice on
- the display, the second time with a small 's' showing. However, maybe
- the small whip antenna is not good enough to allow the SSB circuitry
- to work properly?
-
- Actually tonight for a while, I was picking up some clear signals on
- 3.88 MHZ. Is this a weekly 'show' or get get-together? .. Perhaps
- with the host transmitting with 1 kwatt? I did hear a couple of call
- signs, W8----- something. I wonder if the propagation conditions happened
- to be just right at the time.
-
- Anyway, I guess the rainy weather the last few nights has not been the
- best for radio. When I did finally hear a few minutes of strong signals,
- it increased my level of interest in HAM radio ! The previous two nights
- I was not able to hear much of anything. And when I visited a HAM store
- here last week, I was'nt impressed with the signals I heard as the salesman
- demonstrated a base station hooked up to a 'proper' tower antenna. Granted
- it was during the day. He did finally pick up a fairly strong signal (I
- thought anyway ;) ) which turned out to be coming from Barcelona.
-
- >If this is too technical, just remember that hams use much narrower band
- >signals which can dridt easier.
-
- No, actually it's just about technical enough right now ;) ... I've
- been doing some reading, The ARRL Handbook, among others, and I have
- read a bit about SSB. I was looking through the handbook under 'distortion'
- to try to find the explanation of the pitch shifting. I thought maybe
- what I was hearing was inter modulation distortion. Is it?
-
- I tried to improve the antenna by attaching about 10 feet of wire to
- the whip antenna. That didn't seem to make much difference. However attaching
- a wire to the antenna and a water pipe *did* increase the signal strength.
-
- Anyway, I *will* keep listening :)

- Oh, dear god.. That actually happened to me! When I was studying the code,
- I began hearing it everywhere... Even if the room was totally silent! It was
- probably all in my head, but it drove me nuts.. And the code never really said
- anything, it was just random. Maybe it was a sign of how frustrated I got
- sometimes when trying to study the code.
