Those of you that frequent America Online and The Ham Radio Club there... you
can now access AOL via 9600 bps! If you have WAOL (rev. 38) or PCAOL (1.5a),
find your local 9600 bps SprintNet number, change your settings and off you
go.
Mac users will have to upgrade to the latest software (2.1) which will be
released very soon.
Stop by and join the 16,000 (last months count) other visitors to The Ham

CONELRAD became EBS. The idea was to not provied attacking aircraft
(bombers or ??) with domestic sources for DF. The process was that,
on notice, all broadcast stations were to shut down and only those
that were the local CONELRAD stations would return to the
air and then only on either 640 kc or 1240 kc. They were also to
reduce power when they did, so that there would be no real peaks
in the RF for a DF system to find. The two freqs were so that
all AM stations would have somewhere that they could go without
a major re-tune of the transmitter.

Dave's correct, however, bank selection is possible using the speech
button even when the speech module is installed. The annoying frequency
announement can be muted by rotating the tuning knob.

When the battery dies on this memory board your radio will still
operate. You will loose all 1024 memories. When the radio is
first turned on (after a new battery is installed) there will be
random characters in both VFO's and the memory locations. The
bad data will have to be cleared.

Subject: Opto 2810 Counter specs over frequency
To: info-hams@ucsd.edu
I don't have regular access to special equipment but one day when I had
a few spare moments, I spec'd out my Opto 2810 frequency counter's
sensitivity over various frequencies. I used a Marconi 2022D signal
Generator which outputs from 10KHz to 1GHz and a few feet of an
extremely low loss Andrew cable. All readings were taken when a solid
lock on the frequency occured. Using other instruments, I was able to
get the unit to lock on a signal as low as 5 Hertz and as high as
3.5Ghz. The high end required great amounts of power and I didn't want
to blow the front end so I didn't try and take it above 3.5GHz. The
measurements that follow are over the Marconi's frequency range.

The ARRL Operating Manual gives a procedure for tuning up on CW that is
supposed to give the right results every time for most radios:
1. Turn off the VOX, set mode to CW.
2. Press the key. This will (on most radios, it says) key the sidetone
without keying the transmitter.
3. Tune so that the received stations's signal is the same pitch as the
sidetone.
Make sure the RIT is off when you do this.
The method is predicated on the fact that most radios with sidetones
use a sidetone with a pitch equal to the CW offset. If you don't like
the received pitch, the manual says, turn on the RIT to change it.
Just make sure you turn it off again before tuning the next station.
I haven't had a chance to try this, since I haven't had my keyer, radio
and antenna all in the same place at the same time since I got my upgraded
license. But it sounds logical.

Subject: Use of HT for Marine & GMRS
To: info-hams@ucsd.edu
I have seen various discussions about using the out of band frequencies
on a Amateur band tranceiver for Marine, GMRS or other services.
If a person is an Amateur, and also holds liscenses for other services
can he/she use their amateur radio on those services. Is there a
definitive authority or requlation cite which can be found to make
such a determination ?

In general, no. Amateur radios aren't Type Accepted while the radios
for use in the other services generally must be. Type Acceptance rules
vary a bit by service as well, so radios Type Accepted for one service
may or may not be Type Accepted for another. One facet of Type Acceptance
is that radios must not allow a user to enter frequencies. They must
be preset by an authorized technician to the channels for which the user
holds a valid license. Type Acceptance requires that no control the user
can operate shall allow the radio to operate on a frequency for which the
particular user is not licensed. Now it's sometimes possible to have a
technician program in certain amateur channels in addition to the user's
GMRS or Marine channels in a Type Accepted radio. That's borderline
legal for an amateur. But it's nothing like the flexibility built into
the typical amateur radio.
Note that particular amateur radios may be identical electrically with
Type Accepted radios for another service except for the user interface.
That's true of certain Icom and Yaesu HTs for example. But the different
user interface is sufficient to disqualify them for Type Acceptance
for use on commercial frequencies. In other cases, mainly HF radios,
amateur radios may not meet spectral purity, frequency stability, or
power output limits for another service. Type Acceptance is designed
to "idiot proof" the radios for that service to prevent unwanted
interference. Hams are assumed to know the technical limits of their
service and abide by them, so radios for amateur service aren't required
to be Type Accepted.
Now you would think that because amateurs are assumed to be technically
competent, that's what the tests are for, that we would be allowed to
use our radios in commercial services for which we also hold licenses.
But the FCC hasn't made that exception for us. In their eyes, when we
operate in another service we are no longer amateurs for purposes of
regulation, we're just licensees of that other service.
See Parts 2, 15, 85, and 90 for the gory details.

Yeah, but....
Even during the solar flux peak, I wouldn't have described the 15m or 10m
(CW) Novice subbands as "crowded." They're even less crowded now, as
the solar flux sinks slowly in the west. :-) That's a pity too; they
open up from time to time and they're always good for local contacts and
code practice.
Many is the time I went trolling for Novices/Techs on 15m and wound up
ragchewing with someone other... but I couldn't get much over 10 wpm with
that straight key anyway.
In summary, I don't have a problem with high-speed CW contacts in the
15 and 10 Novice subbands -- the more people we have up there, the better
off we all are. 80 and (especially) 40 are different stories, but I
recognize that higher-class licensees may often run into each other while
trolling. Especially if people like me never upgraded their calls. :-)
(BTW, "trolling" is a method of fishing from a moving boat.)

this is nothing new. Sears and JC Penney has been doing the same for
years (maybe thats why Sears catalog closed down), and you don't
read complaints about paying for catalogs in misc.consumers or other
shopping newsgroups, if there is any.
BTW, I got mine free because I was in their mailing list. and recently,
they have been giving away free flashlights also.

I think YOU misunderstood what Chuck said; he stated he wants to
do his part to help novices increase their speed so they can pass the
General and higher classes license exam. An extra-novice contact would
be a privilege for the novice in this case: Chuck Adams is one of the
top-speed code ops in the entire country [famous but modest]. But that
probably wouldn't impress you.
