I've seen one or two such on a dealer's table at a local hamfest, although I'm not sure that they come pre-marked - the package gave instructions for the number of segments to collapse to achieve resonance on 220 and 440. I think one was made by ADI and/or Premier but I can't be sure. Most HT's can be modified to operate outside the amateur bands, like on GMRS, MURS, FRS, etc. But I don't like doing this without a proper antenna. You really shouldn't do it (well, at least, not transmit) even _with_ a proper antenna. Very few, if any amateur-radio HTs are certificated for transmission on those bands, and using an "opened-up" ham HT to transmit (even if you have a suitable GMRS license) is a rules violation which could cost you your amateur ticket. FRS and GMRS have very strict technical rules about the frequency accuracy of their oscillators due to the tight inter-channel spacings, and it's likely that at least some ham HTs are too sloppy in design (or too poorly calibrated) to hit the frequencies accurately. -- 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! |
