Hi does anyone know if it is possible to get a motorola gp300 vhf high band (146 to 174mhz) to go down to vhf low band 66 to 88mhz.
i have rss to allow this but there would be other issues to deal with tuning ect.if anyone has done this before it would be great to know how to achieve it.Also can anyone recommend a good low band hand held preferably motorola. thanks guys

No matter what you do, you can NEVER make a VHF radio work in the low VHF band, the RF section is a band specific item, and the radio will not work.
If the radio is in the 146-174 mHz. band, you can alter it to work a little above and below its rated band split, but not THAT low, it is impossible!

Your best and only option is too obtain a radio designed to work in that band segment.

radiomanconor,

Are you attempting to utilize the mid-band (66-88 MHz)? If so, you'd be better off to purchase a GM350 or GM950 from the UK. They're relatively cheap, and work quite well, once you get past the 'Euro' programming.

If you want to utilize low-band (30-50 MHz), I'd recommend a Maxtrac. Just keep in-mind that the Maxtrac Series was broken into 3 distinct band splits (i.e. 23-36, 36-42, & 42-50). If you want one radio to cover the entire low-band spectrum (30-50 MHz), there are other options, but the price for the equipment starts to climb.
