Beware of Phony Insurance Certs
the National Association of Tower Erectors LinkedIn page, John
McGarvey, a partner with the Insurance Office of America’s Telecom
Division, wrote recently about the importance of collecting
certificates of insurance from your subcontractors, a prudent risk

do you know if the sub’s coverage is in force or really ever
existed? It’s difficult in today’s world.
may think a certificate protects you; but if you hire a contractor
who has falsified their insurance certificate, you are the loser.

the insurer may deny the claim immediately based on
Telecom Division offers a no-obligation certificate of insurance
audit. They will go through your certificates of insurance and verify
policy numbers, find out if policies are in force and provide you

or not you use John’s service, now is a good time to make a list of
your subcontractors — tower riggers, HVAC, electricians. Any sub
who works on your station should provide you with insurance
certification. Managing this is yet another value-added service that
you, the station or contract engineer, can bring to an employer or

off are emery boards. Think of each as an applicator of “fine
sandpaper on a stick” — very useful for filing down nicks or
polishing corroded terminals and contacts. The length of the board
lets you reach into equipment easily.
are drinking straws, useful for blowing out dust and dirt in
crevices, even blowing out a dropped screw, nut or washer when you
cannot reach into equipment to retrieve it. The length of the straw
lets you aim the air blast, and you can control how much air and how
strong of a blast (or puff) you send.
also likes “yellow stickies” — Post-it Notes brand, or similar
products. These are useful for temporarily labeling everything but
the dog. One can be rolled into a sleeve to wrap around a wire as an
identifier, or cut to any size and used to temporarily label parts,
switches, nearly anything. The slight tackiness allows you to hold
screws or nuts in place while working with them, or to pick up parts
that may have fallen.
best thing about Ihor’s “tools” — their low cost. You can get
straws at a fast food restaurant. A 100-count bag of
double-sided emery boards costs less than $10 on Amazon. And you can
find Post-it Notes in your station’s office supply closet or
S. “Buc” Fitch, P.E., recently changed the blown incandescent
bulb in a Marti SCG-10 SCA modulator to a warm white 20 ma, 5 mm LED.
values that work are a 470 ohm 1/2 watt resistor in place of the
nominal 15 ohm 1/4 watt that is on the meter PCB. Marti once again
has a diode (1N4007) in the circuit to reduce the raw voltage. For
that reason the LED is polarity sensitive. As you look at the PCB
from the front (component side), the plus LED is the right solder pad
that had been used for the bulb.

out LEDs for the incandescent offers long life and reliable lighting.
Thanks, Buc, for the tip.

now, with available technology, we could get plastic replacement
hardware for audio boards, transmitters, etc. — pretty much any
plastic part. But how soon until this technology has other supplies
(ranging from raw material to maybe surface-mount electronics in
“dispensers”) in it so that actual operational parts could be
probably coming. Fairly large items, eight inches to a side, can be
“printed” today using the 3D printer in Fig. 2. It costs under
