After years off the air, I'm ready to get back on. I want to keep it simple though. I picked up a 6m/2m/440 Yaesu VX-7 HT at Dayton and I plan to use it for both base and mobile. This is a reasonable starting place, but you're likely to find that a multiband HT has a couple of limitations which make it less than ideal for use in base and mobile applications. For one: HTs tend to have broadly-tuned front ends, optimized for fairly low incoming-signal levels. This is what's needed to provide wide-range multiband operation with a rubber dummy-load antenna. Unfortunately, as a result, many HTs are very prone to strong-signal overload and intermod, especially when hooked to a good antenna. If you hook an HT to a halfwave dipole or full-length quarterwave whip on a good ground plane, you may find it being "blasted open" by pager signals and other strong local transmissions. This can be a real limitation for base-station operation, and sometimes requires the use of a narrowband notch filter to reject the pager or other strong out-of-band signals. In mobile operations, the lack of a separate squelch control can be a problem on some HTs. Desired-signal and interference levels can vary quite a lot as you drive along, and it's no fun at all (and not very safe) to have to try to hit an HT's buttons to bring up a squelch-setting menu while driving. An HT is usable in both base and mobile situations, but if you find yourself using it a lot you may also find yourself wanting a rig with a more robust front-end. A small mobile radio could serve that purpose in both mobile and base applications. -- 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! |
