Kentucky celebrates successful Phase II training
from the Phase II Disaster
Training at Severens Valley Baptist in E'town last Saturday (8-12-06). Shelby, W8WN and Lora, WD8LPN, members of Severens Valley were excellent hosts.
In the first photo the Communicators do a test on raising the tower. In
the interest of time, we didn't install all of the antennas. In the second
photo Communicators watch a live demonstration of Winlink 2000 and Airmail.
The third shows several observing the coax panel. All radios inside the
trailer are already connected to the panel. When the tower is erected, the
coax harness is attached via color coded connectors.
Training photos were courtesy of Communicator Jim Ingle, K4JNI of Hopkinsville.

Texas Baptist Men has initiated a call out to El
Paso mainly for clean out teams. Communications between the teams will be a
challenge, so I will be going
there tomorrow to assess what communications needs are there. I expect a large need for VHF operations, not much for HF. However, while en route for the 11 hour
drive on Wednesday, I'll monitor and operate on or close to 7.260MHz on the hour, and 14.260ish on the half hours.
Anyone else from Southbears going? We'll be on 146.43 simplex in the work area, unless a repeater is selected to use there. I'll keep you informed.
Hope I can work you.
Rice, the white cap in El Paso for the floods is needing more help.
The need is for communicators (capable of operating cell phones and
possibly a computer). Also there is need for persons willing to help
clean out flooded homes. Also there is a need for pick up trucks for
moving materials and equipment. Ernie says there is at least a week
of work maybe more remaining, but if you can come for even a few
days or a weekend that would be great.
Please pray, and if permissible, go.
Contact Ernie to let him know you are on the way.
To offer or request carpool to/from El Paso, contact Ed Emmons
Living conditions are dormitories with bunks, so bring all bedding
linen, pillows, towels etc.

Common 50 Ohm Coaxial Cable
Used in Amateur Radio
RG-8X is only 24 cents per foot and may work
Ok on HF but at 2M and 70cm, it is VERY lossy.
RG-58 is worse than RG-8X and cost the same as RG-8X RG-213 is Ok on HF and probably OK up to 2M but not 70cm. LMR-400 and LMR-40 UF are the best for up to 70cm at 76 cents per foot. Its also less expensive than 9913 and only slightly more than RG-213.
For my use, I would use RG-213 for HF and LMR-400 (or LMR-400 UF) for 2M and 70cm.
Dave Anderson (the A in FAB-Corp) at http://www.fab-corp.com will sell us LMR-400 for about 72-74 cents per foot and $15 for adding PL-259 connectors on. The cables are tested before shipping. If you mention that you work with SBC Disaster Relief (and of course give your callsign), he may be able to give another 7% discount. Dave sells the real thing and does a good job. His business (in FL) has taken 2 hits by hurricanes in the last two years and he is aware of our chainsaw activities.

5-12-06 As a result of discussions at National Roundtable last month activity is beginning to pick up on the South bears nets. It was decided to better cover the US since propagation is poor was to divide the nets into geographical quadrants. Don Miller, N4ZUV, from Florida agreed to assume the responsibility of Eastern Net Manager and Paul Ridley, N5PR, from New Mexico agreed to assume the responsibility of Western Net Manager. Don has had some success with calling the 40 meter net on Sunday afternoons on 7260 Khz at 3:30 Eastern Time. Paul will be away on Sundays for several weeks and will get the Western segment started in a few weeks.
I spoke yesterday with David Johnson, KB5YLG, near Dallas and asked him if he would mind trying to call a 20 meter net on Sunday afternoons for a few weeks to see if propagation might be favorable on that band. David will call the 20 meter net at 5:30 Eastern, 4:30 Central on 14.260-14.265 Mhz. If you are available that time of day listen for David as he is located pretty well in the South Central part of the US and if conditions are good should be able to hear several of us.
So, for the time being Southbears nets will be as follows on Sunday afternoons:
40 meters on 7260 Khz at 3:30 Eastern N4ZUV Net Control
20 meters 14.260-14.265 Mhz at 5:30 Eastern, KB5YLG Net Control
If you are available during these times please try to check in and lets see if we can't get some activity started back up on these nets.
Ask Yourself "Am I ready? "
Are you really ready for an emergency?
