- In addition to that, I noticed that all of the VHF/UHF spring sprint
- dates are wrong. They've all been moved out by a week. This move IS
- for the better. Now the 2m sprint doesn't coincide with the NCAA
- basketball championship game and the 432 sprint isn't the Wednesday
- evening preceeding the Dayton hamfest, etc..

- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was very low. The majority of today's
- occasional subflare-level activity came from a newly emerging
- active Region 7693 (N09W43). This group showed steady growth
- and development throughout the day.
-
- Solar activity forecast: solar activity is expected to be
- very low to low.
-
- The geomagnetic field ranged from quiet to minor storm
- levels, with some brief major storm periods at high latitudes.
- An initially quiet to unsettled field became disturbed after
- 0300Z and continued at mostly active to minor storm levels for
- the remainder of the day. The source is not certain but could
- be the result of a coronal hole which should be in a favorable
- position at this time.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to be at active to minor storm levels for the next
- 24 hours as coronal hole effects continue. Activity is expect-
- ed to gradually decrease over the second and third days.
-

-
- B. High Latitudes
- Active 35/30/35
- Minor Storm 35/20/20
- Major-Severe Storm 15/05/05
-
- HF propagation conditions were near-normal over the low
- and middle latitudes. Periods of active to minor geomagnetic
- storming resulted in periods of poor propagation over the high
- and polar latitude paths, particularly on transauroral
- night-sector circuits. Similar conditions are expected over
- the next 24 to 48 hours before settling back to more stable
- levels on 24 March.

-
- That's really sort of like it is supposed to be. Since the packet of
- information is sent asynchronously the UART in the COM port will not
- be able to deal with it. So the way BayComm (and the earlier DigiCom)
- worked was to use the computer to decypher the raw 1/0 transitions on
- the RTS and CTS lines. Might want to double check with someone with a
- BayPacc, BayComm or Tiger-Tronics modem and see where they have their
- data hooked up.

- I opened up a commercially available diplexer, and they don't use the caps

- That's true for Germany. The calls being issued now are of the form
- "Danbcd" with:
- a denotes the license class (B, C, D, G for the lowest,
- H for the middle, and
- L for the highest class)
- n is a number without meaning, except 0 mostly for club calls, repeaters, ...
- b stands for the regional district issuing the call (e.g. M for Munich)
- c and d are counted up in alphabetical order.
-
- For example, subsequent calls of the highest class now issued in Munich
- are: DL1MHT, DL2MHT, ..., DL9MHT, DL1MHU, ..., DL9MHU, ... DL9MHZ, ...,
- DL1MIA, DL2MIA, ...

- Subject : RF and AF speech processors. Was: FT-990 vs TS-850
-
- It seems that the SSB quality depends on 3 factors:
- 1. Passband characteristics of the AF chain (including the microphone),
- 2. IMD of the PA,
- 3. Type of processing, audio or RF?
-
- I am wondering why the QST reviews do not mention the type of processing,
- which has a large effect on signal quality. Signals with audio processing
- have higher content of AF harmonics, and are subsequently less efficient
- (3db?) and more difficult to tune. All cheaper rigs such as IC 725-737,
- FT 747-757, TS 430-450 use AF processing. IC 751-, FT990-, TS 830-
- use RF processing. I am not sure about the rest.
