- SYNOPSIS OF ACTIVITY
- --------------------
-
- Solar activity was moderate owing to an M1/2N flare from
- Region 7765 (S12W23) that maxed at 1251Z. It was accompanied by
- a 2695 MHz radio burst of 250 flux units of 15 minutes duration
- (tenflare). Region 7765 declined today in both white light and
- magnetic complexity. No new Regions were numbered. Active
- prominences were reported on the west limb near S04 and N09.
-
- Solar activity forecast: solar activity is expected to be
- low. Region 7765 is still capable of C-class flares and
- isolated M-class activity, but the overall probability of
- energetic events is decreasing as the region decays.
-
- The geomagnetic field has been mostly unsettled for the
- past 24 hours. Isolated periods at active levels were observed
- at high geomagnetic latitudes. Energetic electron fluxes at
- geosynchronous orbit were high.
-
- Geophysical activity forecast: the geomagnetic field is
- expected to be unsettled tomorrow as the disturbance of the
- past few days subsides. A possible new disturbance could begin
- on the 17th in response to interplanetary effects with a long
- duration x-ray event near the center of the solar disk on 14
- August.
-
- Event probabilities 16 aug-18 aug
-
- Class M 30/25/20
- Class X 01/01/01
- Proton 01/01/01
- PCAF Green
-
- Geomagnetic activity probabilities 16 aug-18 aug
-
- A. Middle Latitudes
- Active 10/20/40
- Minor Storm 20/50/20
- Major-Severe Storm 01/10/01
-
- B. High Latitudes
- Active 10/25/45
- Minor Storm 25/50/25
- Major-Severe Storm 05/10/05
-
- HF propagation conditions were near-normal over all
- regions today. A minor SWF may have been associated with the
- M1.2/2N tenflare near 12:50 UTC and could have affected regions
- in all of Africa, Europe, and western portions of Asia.
- Effects may have also reached to eastern portions of North
- America. Propagation conditions are expected to remain
- normal over all regions until possibly the 17th when a possible
- flare-related coronal mass ejection (of the 14th) could arrive.
- If this disturbance arrives, high and polar latitudes could see
- poor propagation with increased levels of fading and periods of
- auroral absorption. Middle latitude night-sector circuits
- could also see minor signal degradation if this disturbance
- arrives. Otherwise, near-normal propagation should persist
- with only brief intervals of below-normal propagation for
- transauroral night-sector circuits.

- Go to next stoplight (about 2-3 "blocks" and is Hibiscus Blvd.).
- Turn left (west) - stay in left lane.
- Go about 3 blocks - you'll see the auditorium on the left.
- Turn onto street just east of auditorium.
- Parking lot entrance is on right about 1/4 way down the block.
- Car pool if you can for Saturday Morning...parking is congested then.

- (why no exams? we tried it for about 3 years...the facility doesn't have the

- To: info-hams@ucsd.edu
-
- I have a G-1000SDX rotor and last night for the first time it started
- doing strange things. By strange I mean:
-
- - while in motion it would stutter every 20 or so degrees for a
- half second then surge forward almost as if it was trying to
- catch up
-
- - while in a resting position it would occasionally oscillate back and
- forth a few degrees as if it was correcting itself after a large
- gust of wind
-
- - after power cycyling the control box, the oscillating disappeared
-
- This behavior happened a few times last night, but not in the half hour
- before I went QRT, during which I exercised the rotor to observe more
- strangeness. It also didn't happen this morning while getting another half
- hour work out.
-
- Has anyone else observed such behavior, and if so, what's the fix?
-
- Thanks and 73,

-
-
- Yep, Beverage antennas really work well on mf, we typically use 4
- strung out in various directions for our dxpeditions to NW Scotland
- each fall. Lengths are between 400 and 550 metres, depending how far
- it is to the sea, and they're terminated at the far end with variable
- resistors usually set around 500-650 Ohms.
-
- They're appreciably directional, switching between antennas on say
- 1100 brings in either R Globo in Sao Paulo, ZDK Antigua or WWWE
- Cleveland.
-
- They're also very low angle, with Alaska for instance still making it
- over the dark North Pole at 1430 UTC (=our local time), and we've had
- sunlight since 0930 UTC

- Ah, semantics. I don't read the term "immediate" that way. There's
- no way to *ensure* "immediate" (in your sense) shutdown even with a
- control link, because the control link can break - or run out of
- batteries! - hence the requirement for a time-out timer under
- telecommand. That must mean that 3 minutes is immediate enough for
- the FCC. (Those poor pigeons aren't as fast as that, anyway! :-)
-
- A number of months ago people around here were forced to DF a
- transmitter. Seems a TNC got stuck in the "on" position. Of course,
- the licensee wasn't home and didn't have a remote link to turn the
- thing off - he had to go home and do it. Now, I wasn't aware people
- with packet stations had to have a remote link to turn the things off
- in just such a case, and it's my impression that nobody has them even
- though they leave them on all the time. Is that impression mistaken?
- Your claim implies that the remote link is required, but I would think
- there'd be plenty of warning in the "Getting Started on Packet" type
- of articles - which there isn't. (Of course, in this case, that
- timeout timer would have worked great.)
-
- Plus, while you are the control op in your example, you are not at a
- control point if the transmitter is under automatic control. If that
- rule means you must be at a control point at all times to turn the
- thing off at a moment's notice, there's no such thing as automatic
- control, only remote control.
-
- In a nutshell, I don't think that interpretation of "immediate" is
- consistent with the plain sense of other provisions of the rules, and
- I don't see that people have ordinarily been interpreting it that way.
