The noise floor is quite a bit lower at 1280 allowing the receiver to
detect much weaker signals. The local 6 meter repeater is a good example
where the guys all seem to use 100 watt mobiles just to put a scratchy
signal into the repeater from 50 miles away. The same mobiles using the
1280 repeater on the same hill are always full quieting using 10 watts.

I bet a 1280 portable communicates further than a 6meter portable of the
same low power.   Rubber Ducks on six ?

1280 penetrates further into buildings and is not prone to pager overload
or the clocks and other oscillators found in computer centers. Well at
least not this year...

Just whistle! No I'm not kidding. Slowly raise the pitch as you're whistling
until you hit 1750 Hz. After a while you'll learn to whistle the right pitch
right off the bat. This can also activate modems too (not useful though).

Subject: 2m handhelds ??
To: [e-mail]

A>    I am planning on purchasing a 2m handheld in the near future.

The HTX-202 from Radio Shack is on sale for $200. this month!
The HTX-202 has 12 independently-programmable memory channels, plus one
calling and three priority channels. It comes with continuous tone
squelch encode -AND- decode. Power output is 5 watts minimum (7w
typical) with 12 VDC supply, 3 watts @ 9 VDC or 2 watts @ 7.5 VDC. Low
power setting provides 1 watt output. A power saver circuit with
programmable 1/2, 1/4, 1/8, or 1/16-second duty cycle. Batteries are
compatible with larger ICOM (IC-2AT/IC-32AT) series HTs.

Repeater offset can be adjusted from 0 to 4 MHz in steps as set
by the scan frequency step selection (5, 10, 20, 25, 50 or 100
KHz). Memories store any offset, and any combination of
continuous tone frequencies.

Size is 65 x 117 x 37 mm.  To put this in perspective, with
alkaline packs on the 202 and my ICOM W2A, both are the same
thickness. The 202 is maybe 1/4-inch wider (at widest part),
and 1/16-inch taller (it's hard to compare because of the
irregular shapes of HTs.)  The HTX-202 does give the impres-
sion of being a "mid-size" HT until viewed up against something
like the little W2A, which actually has three different "widths."

Supplied with Nicad battery, charger, 6-cell alkaline battery
case, antenna, wrist strap and belt clip.

* True FM modulation (not phase modulation) for outstanding
  transmit audio and best performance in packet service.
* Continuous tone squelch transmit and receive tones are
  independently programmable.
* In addition to DTMF dialing, there is 5-digit DTMF selective
  paging (DTMF squelch).
* A five-number memory dialer that stores 15-digit sequences
  for autopatch use or DTMF paging.
* Scan for either active -- or vacant -- channels, with
  programmable scanning step of 5, 10, 20, 25, 50 or 100 KHz,
  and upper and lower scan limits (for VFO scan.)
* FAST, 25 channels/second scanning.
* Selectable priority channel scan interval, every 4, 8, 12 or
  16 seconds.
* Multi-function scanning lets you scan standard memories,
  priority freq. memories, or a frequency range. Resume can be
  after 10 seconds, when carrier drops, or remain on channel
  (don't resume.)
* Transmit timeout - if you frequently time-out your local
  repeater, this circuit will stop transmitting after a preset
  delay (30, 60 or 120 sec.) and sound a beep. In effect, it
  forces you to reset the repeater before the repeater times out.
  Of course you can disable the timeout circuit.
* The HTX-202 carries a 1-year parts and labor warranty.

Subjectively, this HT has exceptionally strong, un-distorted
receive audio you'll really appreciate when walking around the
local (noisy) hamfest. You won't believe the sound is coming
from an HT!  Transmit audio is crisp, clear and strong.

I put a 5/8-wave mag mount on my car, and used the 202 in the
very intermod-rich downtown Ft. Worth, TX area. I've never been
able to use an HT on an outside antenna within 2 miles of down-
town Ft. Worth before. This one performed magnificently. My ICOM
2400 dual-band mobile gets less intermod than any other radio
I've used in this environment, and the HT stayed with it, toe-to-
toe. When the ICOM heard intermod, the 202 heard it, but when
the ICOM was quiet, SO WAS THE HT!!!!

Even more impressive, the HTX-202 heard signals through the
intermod, when the IC-2400 could not pull 'em out!  Reason is
probably because we purposely limited coverage to ham band ONLY!
It can't be modified for out-of-band receive. The design objective
was to build a specialized ham radio product that does the best
possible job on the ham bands, and that includes the tightest,
most intermod-free front end we could design into an HT! The
published spec says intermod attenuation is 60db minimum. Spurious
response and adjacent channel rejection are also 60db.

The HTX-202 is based on the ICOM 02AT with certain design
modifications based on Tandy's specs. These variations include
the encode/decode, additional memories, and a full width LCD
display. Contrary to rumor, no part of the radio is Kenwood or
Yaesu! ICOM sold the rights to their design to Tandy to do with
what they would.

Whan Tandy sought to produce the unit, they went to their usual
Korean source for cheap gadgetry: MAXON. Maxon then built the
HTX-202 for Tandy, under license from Icom. The HTX-202 is
surprisingly sturdy, and well constructed, considering that
Maxon's Quality Control has, in the past, been suspect.

Hi!

The inventors of the BAYCOM modem, also known as poor man's
packet, have just come up with a 9K6 modem. It connects to
the printer port and costs aroune 150 $ or so.

May become a good alternative to a TNC.

Has anyone noticed the crossband repeat volume on a TM-733 to be low? I've
looked at the schematic, and there isn't a pot to adjust this, but a
10K resistor feeds the audio which might be the one to change if I can
get to it...

Anyone looked at this?

Filling the cable with something as Jim suggests will change the impedance
of that section of the cable with bad things resulting.  Splicing on a piece
of RG-8 is an acceptable solution.  This is done all the time with hardline.

Subject: VANITY CALLS - What's the story????
To: [e-mail]

Hello Tony,

I can't speak for all the responses you read, but only for the study
which was conducted by a Committee of ARRL Directors and staffers.
You may wish to contact your Director for a copy of the report, or
read the comments at the FCC reading room as they were submitted.

The ARRL study consisted of a number of surveys via US Mail, packet,
and in-person interviews.  In all, several hundred persons were heard
from in that effort.  The committee reported overwhelming support for
the basic idea, although many suggestions for improving the introduction.
The FCC NRPM would have had a simultaneous availability for all
applicants.  The ARRL proposal, based on the Committee study, recommended
a series of stages so that all the FCC-610V forms didn't deluge
Gettysburg at once.

Current law is what drives the $70 fee ($7.00 per year for a 10-year
license) each time a person renews their license.  ARRL has separately
proposed a one-time up front fee (I believe the suggestion was $150.).
