-
- The Dallas Remote Imaging Group (DRIG) BBS will carry the latest updates
- to the WISP Microsat packet radio programs on the system. Roy Welch (W0SL)
- will be uploading both the entire package and the Dynamic Link Library (DLL)
- updates to DRIG as soon as the executables are available.
-
- The WISP files will be available to all users, even brand new members who
- have not yet fully registered.
-
- To find the latest version, log on to the DRIG BBS in Dallas at:
- 214-394-7438
-
- Your communications program parameters should be:
- 28.8Kbps to 2400 bps (1200 is too slow and not supported)
-
- N parity
- 8 data bits
- 1 stop bit
-
- Log on and if you are a new user, answer Yes to Register with us (if you
- answer no, you will not be able to download files). Answer the requested
- information (type in your own first name, last name, password, city, state,

- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity returned to a low level. Region 7773
- (S08E61) produced frequent C-class flares. Some real growth
- occurred (not just lack of foreshortening) in this region.
- Mixed magnetic polarities were visible in the center of the
- region and a weak delta may be forming there. However, the
- region is basically bipolar. Toward the end of the period, the
- background x-ray flux was decreasing which indicates a slight
- cooling of Region 7773.
-
- Solar activity forecast: solar activity should be low to
- moderate. Region 7773 retains the capability of producing
- isolated M-class flares. An X-class flare from this region is a
- slight possibility. Old Region 7765 is due back to the east
- limb on 03 Sep. This region produced 5 M-class and 10 C-class
- flares last rotation but was decaying in the western hemisphere
- and is not expected to be as active this rotation.
-
- The geomagnetic field was mostly quiet during the period.
-
- Geophysical activity forecast: the geomagnetic field
- should be quiet to slightly unsettled for the next three
- days.
-
- Event probabilities 01 sep-03 sep
-
- Class M 50/50/50
- Class X 10/10/10
- Proton 05/05/05
- PCAF Green
-
- Geomagnetic activity probabilities 01 sep-03 sep
-
- A. Middle Latitudes
- Active 10/10/10
- Minor Storm 01/01/01
- Major-Severe Storm 01/01/01
-
- B. High Latitudes
- Active 15/20/20
- Minor Storm 05/05/05
- Major-Severe Storm 01/01/01
-
- HF propagation conditions were normal over all regions.
- No significant changes are expected over the next 3 days,
- through 03 September inclusive. A gradual increase in MUFs is
- expected over the next week in response to enhanced ionizing
- radiation from Region 7773 and possible additional enhancements
- from old Region 7765 if it returns to the east limb. There is
- a real risk of SWFs on daylit paths during possible flare
- activity from Region 7773.

- NOTES:
- All times are in Universal Time (UT). Characters preceding begin, max,
- and end times are defined as: B = Before, U = Uncertain, A = After.
- 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.

- fine since we will assume that this puts him in talk-back range.
-
- But, if you increase power and the person you wish to talk to was very
- weak, he will hear you better but you will wtill hear him weak.
-
- On the other hand, if you put in a gain antenna, that is a bilateral
- device. It has the dffect of increasing your power (called effective
- radiated power), just as upping the tx output does. BUT, the incoming
- signals *are also amplified by the same amount*. So, the signal that
- might be weak coming in will now be stronger.
-
- Another consideration is the amount of gain you have now vs how much you
- want. For example, suppose you are seeking to double your output power.
- This equals 3 dB gain. Getting this additional gain over a rubber ducky
- is a piece of cake, even a simple home-made co-linear omni would do it.
- But, if you already are using, say a 9dB gain omni, getting another 3dB
- might then call for using a directional antenna. Maybe you don't want
- this complication (i.e., you might still want to be omni). So, if you
- are already at the max from your omni antenna, the best bet might be to
- up the power, especially if those you talk to have higher erp than you do.
-
- Related to the above, if you already have a directional antenna, the more
- gain it has, the harder it is to get an additional 3dB. So, the antenna
- gets rapidly bigger and bigger the more gain you want.
-
- So, to sum up, if you find that your station is rather low powered
- compared to those to whom you are talking, add the increase in the TX.
- This equalizes the talk back. If the reverse is true, then the gain
- antenna might be the best bet.
-
- Finally, this is a rather simple treatment. There are so many variables.
- Like, how much power (poser =weight and bulk) do you want. How big an
- antenna can you go with. How high is your antenna now (higher = farther
- line of sight).
-
- I hope this short and rather unscientific reply gives you some food for
- thought.

-
- I am new to Ham Radio and am unsure were to start from. I found in
- Radio Shack 2 books "Now you are talking" and "No Code Plus".
- I know that the 2nd has the test pool, but I was told that I need the
- first one to build some background knowledge in Ham Radio and electronics.
-
- I do not have any background in electronics other than computers so what
- should I do? Get #1, #2 or both, and maybe why?
-
- I am in the process of reading the FAQ right now but I need to solve this
- question soon.

- Mode-B : MA 30 to MA 150 |<- OFF Oct 22 - Nov 07 for eclipses
- Mode-B : MA 150 to MA 190 | max duration 2h 12m
- Mode-BS : MA 190 to MA 218 |

- The battery charge state is of paramount importance during the eclipse
- seasons. As always the command team may have to have to make temporary
- changes to the published schedule. In that case we will try to minimize
- the inconvenience, setting Mode-B OFF from MA 230-256 in the first
