I'd like to use my HT in the car. I figure why should I buy the remote
microphone when the HT itself is the size of a microphone. All I need is coax that is flexible enough to withstand the rigors of a mic cable. Anyone know of a source of flexible coax? (I have a few feet of Columbia Super-Flex RG-58, but it's 35 years old and really beat up. Do they still make it?) -- Bob D. ND9B |

All I need is Some portables get so hot on 12V (13.6V) that you can't hold them after a short period of transmission. One of the benefits of a 5W matchbox sized radio! Owen -- |

Helps rein in the motor-mouths. What the OP needs to be concerned about is not so much the flexibility of the feed line, but, rather, the sturdiness of the coax connector at the HT. That 'joint' will take a lot of stress in such a mode of operation. Not only will there be problems at the point where the coax enters the male connector, but the large stresses on the female connector will oft times ruin the internal attachment to the pc board. Back before the banality of VHF FM operations drove me away, I would make up a little plastic 'back-board' that attached securely to the HT and extended up a ways to help support the coax. As well, I slipped some over-sized tubing over the coax to move the flexing away from the coax connector.

I've also found that HTs are less than ideal for mobile ops for another reason - squelch. Most of them do not have a separate squelch knob - you have to go through a menu to change the squelch setting. Not a good thing to do while driving - it's the sort of thing which makes J. Random Cellphone User's distracted behavior seem downright civilized. Add to this the fairly wide-open nature of most HT's RF front ends, (and the resulting sensitivity to intermod), and the amount of 2-meter RF noise and birdies from cable leakage, etc., and you end up with a bad mixture. An HT with a magmount antenna will do in a pinch, but I don't feel that it's a good long-term frequent-user solution in an urban area. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
