How about some information on what the vanity callsign program is and what
stage of proposal or reality is it. Does that mean I could get back an
old call I held if it hasn't been reassigned??

Maybe you mean the very early ones that Yeasu shipped.
The more recent one supplied with the FT530 seems to work
very nicely. I'd say it is second only to the Diamond R77
in my collection. That one seems to be king of the duckie

Anyone have experience running a rotator with a power inverter?
The specific question is will one of the smaller rotors work with the
$100/200W units? Primary interest is use a backup power supply (marine
battery) for emergency services. I know that some of the cheaper
inverters only put out square waves. Does this cause a problem?
Thanks in advance.

My father uses a TS 50 and an IC901 in his taurus. only noise is slight alt whine
on the 901. Only effect caused by xmitting is changing the speed of the key-in-ignition
chime when xmitting on 440. He's happy with car.
Of course I hold onto my old 71 VW bus. Point ignition, generator, etc. all waay in the
back, entire body grounded, lotsa room for rigs, etc. I'd hate to lose that car!

...until I looked in the back pages of a QST. Try the EMARS group and
their chest harness ($29.95 + $3.50 S/H). I bought one and it is
very well-made. I use it primarily when biking but also emergency

Subject: HELP: Hallicrafters Model S-76. SSB no good!
To: info-hams@ucsd.edu
This weekend my Brother-in-law "dug-out" (literally) a SW radio
Hallicrafters S-76. It is a 9 tube unit double conversion Superhetrodyne
receiver.
I threw on a single long wire (will improve this later) and turned it on
lo and behold it warmed and started to work. My B-in-L estimated that the
unit wasn't powered up for AT LEAST 15 years .
I jumped to the 80 meter band and recieved CW fine. however when I went up
in the band to do SSB I go lots of signals but they were all distorted/muffled
The unit has a switch for either CW or AM reception. The manual says that if
I use the narrowest (sharp) filter and tune in the station then switch to
the widest filter it will then be ok for SSB reception.
The afore mention switch engages a BFO when switched to CW mode, but I
didn't read anything about AM.
Has anyone used one of these old birds?? Has modern technology of todays
transmitters made this units SSB or Psuedo-SSB capabilities a thing for
the muesum shelf (although it work fine for CW!!)? Maybe something is lacking
due to age or lack of use??
Many thanks for reading

You are probably overdriving the detector. With the BFO on, the AGC
doesn't work, so the incoming signal can easily overdrive the detector.
(It's not a problem on CW since distortion doesn't affect copyability.)
Try turning down the RF gain control.

I have an old Hallicrafters like yourself. The SSB reception
is very touchy. CW mode is right, but you then need to use the band
spread knob to very carefully adjust the frequency. The pitch control
also helps on this.

I just took 3b and 4a this weekend. I went to look at the available exam
prep books today (neat coincidence). Anyway the W5yi stuff was really
nothing but the questions and answers with just a little bit about the
reasons or process. The AMECO books were slightly more indepth with
regard to the answers. The ARRL book was definitly the way to go. It is
organized with all the theory and regs in the front of the books with the
appropriate questions listed at the end of the section so you can look at
the exact questions.
I bought the ARRL book. Can't give a recommendation for tapes though, I
am trying to use Super Morse. Still haven't passed 1b or 1c yet.

Plug them into the parallel port. Optoisolation is a good idea, but
beyond that, control is pretty direct. The serial port control lines
are also handy.

Jon,
If you live in a metropolitan area then I recommend that you NOT buy a TM-732. I live in Dallas and had to get rid of mine in less than a year.
It is a feature-laden radio, but it has poor rejection. As a result you hear lots of "intermod", even with CTCSS decode turned on. If you look at the service manual, there is only one adjustment pot in the receiver, which only helped the problem by deafening the receiver to the point of unusability.
In the home or in rural areas it would work fine. In heavy RF environments it becomes very annoying. I have at least 6 friends with the same radio and the same problem, but since they don't go downtown very often they have just put up with the occasional racket. I couldn't. I bought a TM-742 that has individual band modules and it works great. (See, I'm not anti-Kenwood!)
I don't know anything about the Yaesu FT-5100. Hope this helps.
John

Subject : Re: Best cars for mobile HF/VHF??
My VW Diesel (now long gone) was an excellent radio platform. It was
almost noise-free (slight alternator whine), and had a huge battery. Using
LORAN-C (which is very noise-sensitive) in the Diesel was no problem.
Almost everything in my '93 Toyota truck makes RFI, including the cruise
control, heater fan and wipers. The major problem I've found with new cars
(with the possible exception of vans) is that there's no place to mount
radios.
