Hi again Gordon and all,
Thanks for the kind remark, it's good to be back! Well, with a
troublesome node in NY I'll be at it at least until lightning strikes the
antenna again.
I see you're a trickster with PSK31 too, we have to be in such high noise
environments and with a very strong nearby signal it's imperative we
narrow the bandwidth and fiddle with the RF gain. Then too the AF receive
gain plays a big part, internal receiver noise and stray signal pickup on
the cables you know. My setup is only half done, receive only at this
point so I'm not fishing around on VHF with it or any other "exotic" mode
yet and then there is the antenna polarization problem, vertical only at
this point. I have a LOT of work to do but like the proverbial turtle
with minimal funds I'll get there.
You don't have to go fishing during your tests, have you guys tried QRP
to find the signal threshold? The usual power is about 30W but drive it
less and see what happens, hopefully circuit noise won't foul it up. If
push comes to shove an attenuator just might do the trick, I remember a
sub-QRP test using a calibrated attenuator on 80M that was simply
amazing. The signal threshold was found when 5uW, yup, that's FIVE
MICROWATTS ERP transmitted from Annapolis MD was heard on Cape Cod MA and
it was >AM< no less! I was in northern NJ at the time and what FLOORED me
was I heard it on a National NC-173 boat anchor and a half wave end fed
inverted L antenna. Not only were the radio gods smiling but angel music
was heard, after all that's what AM stands for.
I can't answer such verbosity so I hope this is enough for now, just keep
on experimenting in true Amateur Radio style! Nothing pleases me more
than keeping in tune with what every nation and the ITU has in mind with
what's found right at the beginning of the rules, the very reason for our
existance. Just to add a bit of verbosity of my own, here's a reminder
American style.
Subpart A--General Provisions
Sec. 97.1 Basis and purpose.
The rules and regulations in this part are designed to provide an
amateur radio service having a fundamental purpose as expressed in the
following principles:
(a) Recognition and enhancement of the value of the amateur service
to the public as a voluntary noncommercial communication service,
particularly with respect to providing emergency communications.
(b) Continuation and extension of the amateur's proven ability to
contribute to the advancement of the radio art.
(c) Encouragement and improvement of the amateur service through
rules which provide for advancing skills in both the communication and
technical phases of the art.
(d) Expansion of the existing reservoir within the amateur radio
service of trained operators, technicians, and electronics experts.
(e) Continuation and extension of the amateur's unique ability to
enhance international goodwill.
