- 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. :)

- 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
-
- A. Middle Latitudes
- Active 15/30/30
- Minor Storm 05/25/25
- Major-Severe Storm 05/15/15
-
- B. High Latitudes
- Active 25/30/30
- Minor Storm 10/25/25
- Major-Severe Storm 05/15/15
-
- 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.

- 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).

- 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:

- 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.

-
- 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.
