NOTE: The Effective Sunspot Number for 30 DEC 93 was 63.8. The Full Kp Indices for 30 DEC 93 are: 1+ 0+ 2- 2- 2- 1+ 1- 0o SYNOPSIS OF ACTIVITY -------------------- Solar activity was low. Intermittent C-class activity was the order of the day, with the brunt of the flares originating in or near the Region 7640 (N08W80) complex. Reports characterize this area as being largely stable. Region 7645 (N11E43) in the opposite hemisphere had only a few small flares, but remains complex magnetically. One new region was born on the disk, 7647 (S15E34). Solar activity forecast: solar activity is expected to be low to moderate. Regions 7640 and 7645 hold the best promise of an isolated M-class event. The geomagnetic field was quiet early in the period, then experienced minor to major storm conditions at the midway point. This disturbance, thought to be related to a western hemisphere coronal hole, now seems to be weakening. Geophysical activity forecast: the geomagnetic field is expected to be predominantly unsettled, with episodes of active conditions likely during local nighttimes. Event probabilities 01 jan-03 jan Class M 50/50/50 Class X 05/05/05 Proton 05/05/05 PCAF Green Geomagnetic activity probabilities 01 jan-03 jan A. Middle Latitudes Active 25/15/20 Minor Storm 25/05/10 Major-Severe Storm 05/01/01 B. High Latitudes Active 30/15/15 Minor Storm 30/05/25 Major-Severe Storm 15/01/01 HF propagation conditions were near-normal over the low and middle latitudes. Conditions were more unstable for the higher latitude paths due to periods of increased geomagnetic and auroral activity. Occasionally poor propagation conditions existed over the night-sector high latitude paths, particularly on transauroral circuits. Similar, if not improving, conditions are expected over the next 72 hours. Near-normal propagation should return to all regions by 02 or 03 January.

Tip and Ring is the name for the two wires that carry >JU>the phone signal. > > Any particular reason why 250V? That is the standard for such applications in the telephone industry. Why 250V and not say 90V? Well, first of all, telephone equipment is designed to withstand massive surges - 1,000V at 1,000A is a Bell System surge test. This is to withstand the sort of crud that is liable to be found on a phone line. These sort of surges can occur from power lines falling on telco lines and with induction from lightning strikes. Then the standard ringing voltage is between 40 and 150 Volts AC (Usually 20Hz). Don't forget the capacitor voltage rating is DC. A 250V capacitor will tend to survive these lab tests and survive in the field too. Often equipment is sold that is not built ruggedly enough - capacitors and semiconductors that work on a perfect line will fail any stormy day in Kansas. In most telephone equipment, Polyester film (It's not just for leisure suits anymore) capicitors seem to be the best. If subjected to overvoltage, they will often "flash-over" and puncture the film but will not short or open after the event. The best polyester film capacitors for telco use are Rifa capacitors made by L. M. Ericsson. For documents on signals and voltages telephones are subjected to see FCC Part 68 and Bell Pub 48005. -- Julian Macassey, N6ARE julian@bongo.tele.com Voice: (310) 659-3366 Paper Mail: Apt 225, 975 Hancock Ave, West Hollywood, California 90069-4074 ------------------------------ Date: 1 Jan 94 02:48:35 GMT From: netcomsv!netcom.com!netcomsv!zygot!ravel!duncan@decwrl.dec.com To: info-hams@ucsd.edu References <horak.757274780@convex.com>, <CIv74H.7LK@stortek.com>, <2fvl4d$1ul@chippewa.pd.tgi.plexus.com>n Subject : Re: Ramsey kits not too good?
