The one person I know who did it, got poor RX afterwards. Not sure what the SMD does that was removed, but it appears to have been part of it's filtering network.

Nope,and it is not legal. Despite this being a group of "Misfit Hams"?

www.mods.dk (http://www.mods.dk) probably has it somewhere. Or the Dark Web?

That is all. No offense.

Modifications


The VX-3R can be modified to transmit on MARS and CAP frequencies through hardware techniques, however this radio does not meet NTIA standards for either MARS or CAP.

The hardware modification requires the removal of an SMD located under the battery pack.

This radio is also a preferred radio of Hacktivists (http://www.wikiwand.com/en/Hacktivists) and as such is the subject of some unusual and exciting mods.[citation needed (http://www.wikiwand.com/en/Wikipedia:Citation_needed)]

It is capable of being programmed by the open source Chirp software.

The best 220MHz mod is to buy a VX6, VX7 or VX8.

The only real solution to get on 220, fwiw.

Alinco makes a 220MHz mobile rig.

Well, I meant get a rig designed for 220, not so much the brand itself (Although, I am partial to Yaesu).

The folks around here bitch about 220 being dead sans the little private family repeaters. None of them will part with their equipment for that band.

NTIA provides a set of recommended standards. As far what is legal, spectral purity wise, that is the role of the FCC. It is still illegal, not by NTIA standards, but by the fact that the transceiver doesn't meet the requisite type acceptance.

I have a TH-F6A. Full 5 watts on 220. Kenwood also has come out with the TH-D74A that has 220, but it is expensive.

I can throw my Yaesus in the creek, fish them out and keep using them like nothing happened. If the Kenwood was waterproof (not just "resistant") I would have bought it instead.

My VX6 and VX7 have seen a lot of wet weather. Snow, sleet, torrential downpours while affixed to motorcycle and bicycle alike. Vertex and Horizon (Standard) offer models of the same line which - in addition to the 2M amateur band - cover either the VHF-AM Aircraft allocation or the VHF-FM Marine band. Both waterproof as well, and both use the same accessories as the amateur rigs. If I had a boat or a plane, I'd definitely have one of the V/H/S radios along.
