- Since no one else has picked up on this, I'll put in my recollections.
- Back in the early 70's, someone from the local Heathkit store spoke at
- a club meeting and advised us not to use the 6146B version. I don't
- remember if he was clear on the exact reason but my guess is that the
- capacitance in the "B" is different and can't be neutralized by the
- Heathkit circuit. I never used the "B" and I've had at least three
- transmitters with 6146's. (Boy I hope I'm not the oldest OF on the net.)
- Two of those transmitters are on the same table as my TS440 and all
- have been used within the last year.

- Subject: QRZ Beta Testers Needed
- To: info-hams@ucsd.edu
-
- The QRZ! Ham Radio CDROM Volume 3, June 1994 Edition is about
- ready to go to print and we need volunteers who are willing to
- Beta test the new QRZ-II Windows software.
-
- The new QRZ-II software is written in Visual Basic and uses a new,
- QRZ Dynamic Link Library (.DLL). The DLL is compatible with VB
- and should also be compatible with C, and C++, VC++. If you're
- a software developer and would like an advance copy of the DLL,
- please indicate so separately.
-
- The QRZ-II software has a number of enhancements over the previous
- versions of QRZ Windows including enhanced printing with adjustable
- fonts and sizes, recently accessed callsign memory, new .DBF
- output file formats, improved name searching and more.
-
- I'd like to get 10 or so volunteers who would be willing to test
- the software on their systems and report back to me via e-mail.
- As a bonus, the top 6 bug reporters will receive a free copy of
- Volume 3 when it becomes available.
-
- If you'd like to be a QRZ Beta tester, here's what you'll need:
-
- o Your own copy of the current, December 1993 QRZ! CDROM
- o A PC running Windows 3.1 (hopefully a 386 or better) or -
- o a higher level system such as NT, OS/2, Wabi, or Soft Windows
- o Access to Internet ftp for the code
- o An Internet e-mail address
- o A sense of humor
-
- Sorry, but I can't honor requests for those who are only "interested"
- in the new software. Instead, I need volunteers who will actively
- use the product and report back on their progress. The length of
- the Beta program will be approximately 2 weeks (gasp! is that all!?!?)
- and will begin immediately.
-

-
- Yes it would, but you can't because glass doesn't make a good RF ground,
- and any length of conductor over to a good RF ground has inductance. They
- tell you not to mount the antenna within 2 inches of the edge of the glass
- because the presence of metal near the antenna base screws up the capacitive
- coupling. That's also why you can't mount them over heater wires or over
- metalized glass tinting.
-
- If you can get a good *short* low inductance coupling to RF ground from
- the coax shield at the antenna base, you can keep most of the RF off the
- coax. A piece of 5 inch wide copper flashing a couple of inches long
- should work. Get much longer and you're an appreciable fraction of a
- wavelength at 440 MHz. However, if you connect to the edge of the windshield
- frame, it becomes a slot radiator antenna, not the ground you were hoping
- to find. The window frame actually makes a pretty good slot radiator at
- two meters. That's why hooking up the little ground wire/tab they supply
- often makes RF in the cabin problems *worse* not better.
-
- You could try slipping several large ferrite beads over the coax to
- form a choke balun. That might work OK, but looks unsightly hanging
- in the window.
-

- >and about 95% above the roof itself (depending on the exact shape of the roof).
-
- The entire whip isn't above the window. At least 5 cm of it has to be
- below the window edge to reach the capacitive coupled base. That's a
- lot at cellphone frequencies. And mounting close to the window
- frame can excite the frame as a slot radiator as mentioned above. Of
- course cellphones don't run much power, and don't need much of an antenna
- to perform satisfactorily, so through-the-glass antennas are good enough
- for that application. However, with ham rigs running 45 watts and operating
- on 2 meters or 70 cm, they just aren't very good, or very safe from the
- standpoint of RF exposure in the cabin.
-
- In my truck, I use a Comet dualband antenna mounted in a hole in the
- center of the roof, and a triplexer, to handle 2 meters, 70 cm, and
- cellphone. The antenna really isn't resonant for cellphone, but like
- I said, it doesn't take much for cellphone, and the phones don't seem
- to care that they're operating into a mismatch. Getting the antenna out
- in the clear seems more important.

- Their sole purpose in life is to give you hundreds of amps for a few
- seconds for as many days as possible. If you put them into cycling
- service such as for battery op radios, they will have a very short life.
- They aren't constructed for cycling and a few deep discharges will do
- them much harm... get a deep cycle (marine/rv/golf cart) battery.
- They aren't that much more expensive, and they are rated to do what you
- want.
-
- If you still feel compelled to use car batteries (they are cheap), a
- useful figure is the "reserve capacity", defined as the number of
- minutes a fully charged battery will supply 25 amperes at 25 degrees
- C to 1.75V per cell. (That 77 deg. F for you metricphobes). This
- should give you some indication. Most batteries I've seen are in
- the 80 minute range.
-
- Good luck.
