WATERPROOFING<br />
Please send us the names of<br />
stores that carry the materials<br />
mentioned below so that we know<br />
where to go along with their current<br />
product designations and prices.<br />
PVC tape, SCOTCH 33+ or<br />
equivalent is good for wraping over<br />
·se1f-ama1gamating- electrical tape<br />
(SCOTCH 23 rubber splicing tape)<br />
since amalgamating tape breaks down<br />
with UV 1 i ght •<br />
Terminal blocks on rotators,<br />
Corning silicone grease. MS4.<br />
00 NOT use common RTV sealants •<br />
They emit a strong vinegar smell and<br />
will corrode electrical connect10ns<br />
to nothingness within a year.<br />
Dow Corning Si1astic 738 is good<br />
for corrosion sensitive connections.<br />
Real critical connections could use<br />
Dow 3145 Hi-Tech RTV. Wrap first<br />
with Scotch 23. then pot w1th Dow<br />
738 for a good joint. Clean all<br />
connect10ns f1rst with Dow primer<br />
1200. Rubber surfaces lightly<br />
sanded and acetone wiped.<br />
Coax-SEAL 1s good for sealing<br />
coax1al cable. It goes on 11ke S111y<br />
Putty, is easily molded. and can be<br />
removed in cool weather.<br />
The gl ue from a -heat-gun M will<br />
seal coax connections.<br />
GOOP by E1ectic Products seems to<br />
work well as a sealer of coax cable.<br />
Its found in many stores in the glue<br />
department. It repa1rs almost<br />
everything.<br />
Heat shrink tubing sometimes<br />
works well - also in combination<br />
with other methods.<br />
And don't forget to wrap the<br />
connection with electrical tapeeven<br />
if you use the above methods.<br />
Some people ·layer- glue and<br />
electrical tape. Remember that<br />
water in your coax is death to your<br />
s1gnal going out and coming in to<br />
your radio. Put -drip· loops in<br />
your coax where needed.<br />
Any more ideas on sealing coax<br />
connectors from the weather?<br />

One of the most frustrating<br />
things about the using of handitalkies<br />
is that the battery that<br />
comes with the unit only last for<br />
several hours. It is suggested that<br />
you can extend the usefu11ness of<br />
your HT in everyday use and during<br />
emergenci es by:<br />
1) Using a 12vDC car plug<br />
2) Buying several empty battery<br />
cases that hold 6-8 nicads<br />
3) Using low power when possible<br />
4) Using the HT -battery saver<br />
5) Use a plug-in 2-10AHr battery<br />
6) NEVER turning the HT on<br />
I buy all my nicads from PRICE<br />
CLUB and use their CC-8 charger.<br />
Buy one more set of 6 cells than you<br />
have cases so that you can<br />
immediately replace the used cells<br />
with freshly charged cells. Our<br />
family has four HTs and each HT has<br />
its original battery case plus two<br />
6-ce11 cases plus 6 extra cells for<br />
a total of four uses. Our charger<br />
is always busyl Store your charged<br />
cells in the refrigerator to cut<br />
down on the cells self-discharging<br />
lilday. This makes for real cool HT<br />
operation. de W9FQN<br />
