Region 7671 (N10E52) produced a C1/SF at 15/0757Z. Solar activity forecast: solar activity is expected to be low. Region 7670 (N11E38) and Region 7671 have slight M-class flare potential. The geomagnetic field has been at unsettled to active levels at mid-latitudes for the past 24 hours. Some high latitude stations reported severe storm conditions for the period 15/1200-1500Z. Energetic electron fluxes have been at elevated levels since 07 Feb. One historic note regarding the past ten days. A-Fredericksburg values have exceeded 20 since 05 Feb 94. This has only occurred two other times since 1957 (beginning 27 Mar 1984 and 04 Jun 91). Geophysical activity forecast: the geomagnetic field is expected to be unsettled. A coronal hole may bring a return to storm conditions on day three. Event probabilities 16 feb-18 feb Class M 05/05/05 Class X 01/01/01 Proton 01/01/01 PCAF Green Geomagnetic activity probabilities 16 feb-18 feb A. Middle Latitudes Active 25/30/30 Minor Storm 15/25/25 Major-Severe Storm 05/01/01 B. High Latitudes Active 25/30/30 Minor Storm 15/25/25 Major-Severe Storm 05/05/05 HF propagation conditions continue to show signs of improvements, particularly over the low and middle latitude regions. However, high and polar latitudes are still experiencing poor to occasionally very poor propagation. Improvements should continue until about 17 February when effects from the second coronal hole noted above should herald a return to slightly more disturbed conditions.

One of the first things we've decided that we need/want to do is an assessment of our primary and secondary communication response points (and then work out from there). Towards that goal we're trying to develop a form that will document the salient issues for us. For example: . directions to the site . possible problems: bridges/overpasses, flood plain . resources available: power, antennas, radios... . issues of concern: where and how to run cables, RF interference... We have a pretty good start at what we think should be on the form, but we're wondering if anyone else has already done a similar type form and if they'd be open to sharing it with us? Thanks much.

This area is accessible via: anonymous ftp, gopher, and World Wide Web (and possibly other methods I'm not yet aware of). World is not *fsp*-able yet (I asked them). Via Gopher, the easiest path to the area is by selecting the following from World's main menu: 18. Membership and Professional Associations 3. Boston Amateur Radio Club And go from there... Please feel free to browse through the area. If anyone has any questions about it, please do not hesitate to e-mail me. Also, up-to-date copies of the files on the ARRL's information server (info@arrl.org) are available in the directory pub/hamradio/ARRL/Server-files. All text files are uncompressed, so they are both retrievable and viewable via Gopher and World Wide Web. (If you have any troubles with any text file, please e-mail me).

Err... settle down Cecil; I think Jeff is mentioning that the assembly manual didn't say you needed to stretch the coil. Settle down, Cecil. Jeff had a certain experience that differed from yours.

Is it cheaper buying one of these kits than it is buying the individual components? Scrounging around for all the parts you need to build a project is not all that easy. I know. I am building the swr/power meter present in the ARRL handbook and am having a beast of a time finding the proper ferrite beads. The local vendor does not carry Amidon beads and I can't find out the appropriate values for the Amidon part so I can buy the equivalent.
