- I run 2 meters, 70 cm, and cellphone in my truck. I use a Comet
- triplexer and a Comet dualband antenna. It's worked fine, but
- I've never tried transmitting on all three bands at once. It's
- very unlikely that the 70cm or cellphone will bother the 2 meter
- receiver, but the 2 meter transmitter may bother the 70 cm receiver
- and the 70 cm transmitter may bother the cellphone. I doubt you'll
- see any actual damage, however. The triplexer I use gives me more
- isolation than parallel separate antennas, so your problems may
- be more severe.
-
- Note that I'm using a dualband antenna for three bands. That's
- not ideal, but it seems to perform well with the cellphone.
- Comet does make a triband antenna, but it's a good bit taller.

-
- You might add
- Look for obvious cracks...the smaller ones would have to be

-
- What is the galvanize like? Still good? corrosion?
-
- I think I would be more concerned about the first 7 years than the

- the sections were not drven on, beat on, and in general abused.
-
- Another thing you might inquire about is what was the size of the

- Greg, those are good batteries for running HTs. You are only partially
- charging them though. The terminal voltage of a fully charged lead-acid
- cell should be 13.8 volts. This is only a "surface charge" that will
- quickly drop to about 12.5 volts under load. What you want is a constant
- voltage charger with current limiting. For slow charging, apply a voltage
- of 13.8 volts to the battery. It can stay on charge indefinitely at that
- voltage. For a more rapid and complete charge, use 14.5 volts and watch
- the battery temperature. When it starts to get warm, drop to 13.8 volts
- on the charger. Alternatively, a pulse charger can be used with voltage
- sampling between pulses. When the battery terminal voltage reaches 13.8,
- it's charged. Set the current limit so that you don't exceed the rated
- 0.88 A when the battery is first placed on charge. It'll draw more current
- when it's terminal voltage is low. As the terminal voltage increases,
- current draw will drop.
-
- A lab power supply makes an adequate charger. I've used the little
- Radio Shack lab supply for this purpose. One caveat, however, make
- sure you use a diode between the supply and the battery. If you don't,
- and the lab supply's AC power is interrupted for a moment, the battery
- will blow the 723 regulator IC in the supply. Allow for the 0.6 volt
- drop across the diode when setting charging voltage. I blew the regulator
- ICs in both the Radio Shack supply and in an Astron supply before I
- caught on to this problem. If you have something like a Systron-Donner,
- Motorola, or HP lab supply, they're already reverse voltage protected.
- Still, if you aren't sure, the diode is good insurance.
