To: info-hams@ucsd.edu
Just out of curiosity, how tough is it to find 6JS6C tubes, anyway? I believe
that I saw someone mentioned they were expensive... What are they going for
now? (I can't remember the ones I last used in my FT-101B, maybe GE?) These
replaced the NEC's that were in there along with the associated mods for
neutralization. I would like to have a spare set handy, but right now I can
only afford to be curious as to how much they are going for. :)

SOLAR AND GEOPHYSICAL ACTIVITY INDICES FOR 27 MAY, 1994

NOTE: Background x-ray levels were below class A1.0 levels. X-ray levels
below B-class are generally considered unreliable, but attest to the
low state of activity presently on the Sun.

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. The solar disk is spotless.
No flares were observed.
Solar activity forecast: solar activity is expected to be
very low.
The geomagnetic field was quiet.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly quiet until the beginning of a recurrent
disturbance sometime on 29 May.
Event probabilities 28 may-30 may
Class M 01/01/01
Class X 01/01/01
Proton 01/01/01
PCAF Green
Geomagnetic activity probabilities 28 may-30 may

B. High Latitudes

HF propagation conditions were normal over all regions.
Near-normal propagation should continue on 28 May. On 29 May,
the anticipated arrival of the coronal-hole related disturbance
should degrade communications over the high and polar latitude
paths. Degradation is expected to affect the middle latitudes
as well, mostly during the local night hours. Expect reduced
MUFs, increased noise and signal instability for at least the
next week.

NOTES:
All times are in Universal Time (UT). Characters preceding begin, max,

All times associated with x-ray flares (ex. flares which produce
associated x-ray bursts) refer to the begin, max, and end times of the
x-rays. Flares which are not associated with x-ray signatures use the
optical observations to determine the begin, max, and end times.
Acronyms used to identify sweeps and optical phenomena include:
II = Type II Sweep Frequency Event
III = Type III Sweep
IV = Type IV Sweep
V = Type V Sweep
Continuum = Continuum Radio Event
Loop = Loop Prominence System,
Spray = Limb Spray,
Surge = Bright Limb Surge,
EPL = Eruptive Prominence on the Limb.

Many of us have scanning HT's or mobiles, and we use them to monitor several
repeaters at once. When driving, or otherwise unable to watch a display,
the method described on the top line above helps immensely when one hears
someone to whom one wishes to speak on a repeater. You see, not only
"scanners" scan. Some of us have scanning *transceivers*.
By the way, I agree with your opposition to the "don't rock the boat" school
of argument. When that method of argument is used, it usually means there
is no real substantive reason to maintain the status quo (or at least the
person wanting a steady boat is unaware of one).

Subject: RTTY PD software.
To: info-hams@ucsd.edu
Can anyone suggest any NET sources of PD software, preferably with
source code in 'C' for decoding of RTTY Met data, ideally using a
simple interface such as the John Hoot Software Systems 741 op-amp
unit or the same type of unit detailed in the JVFAX documents.
I have written a program to decode the UK Bracknell transmissions
of AAXX, TTAA, SFLOC & CLIMAT in baudot met code to graphs and maps
of the station locations and data for all European countries. Whilst
I am using a PK232 (Pakratt) I would like to try my program out with
a simple demodulator, but apart from buying SWL, I don't know know of
any sources.
Any help appreciated.

9 MHz crystal filters "for the experimenter" are available from:
International Radio and Computer, Inc.
3804 South U.S. #1
Fort Pierce, FL 34982
Phone (407) 489-0956, Fax (407) 464-6386.
They cost $75 each. Five models for SSB range from 1800 Hz to 2400
Hz, with shape factors of 1.6 or 1.8. They also have models for CW,
AM, and FM. This company also makes filters designed for Icom,
Kenwood, Yaesu, Heath, Drake, and Collins radios.
I have no affiliation with them, I just happen to have their latest
catalog handy since I was looking into accessory filters for my rig.

To: info-hams@ucsd.edu
On may 28'th we will interview Larry Ledlow NA5E. Larry has just
returned from an assignment with the un in Croatia and Bosnia. He will
clue us in on the communications scene in that troubled part of the
world.
On Saturday June 4'th we will take a look at Digital Audio Broadcasting
or DAB. This high-tech system of broadcasting is in the wings and
should be here near the end of the century. A few systems have been
proposed for dab and a standard hasn't been decided as of yet. Our
guest will be Ted Schober. Ted has been on the leading edge in the
world of DAB and will give us a look into the radio of the future.
On Saturday June 11'th we will take a look at vsats, (very small
apachure earth terminals). Vsats are the newest high-tech method of
satellite communications. Our guest will be Bill Septmeyer. Bill is an
engineer and founder of National Supervisory Network (NSN). Nsn is on
the cutting edge of this new communications technology. So join us on
the 11'th of June when we take to the sky on Spectrum.

I think from Sandland's use of the terms "rfc" and "faq" he meant a
net.source, not snailmail! Surely there is a net site that has the
info.
We could try the arrl's info server. Send mail to:
