It's situation dependant, but it's very likely it would help considerably.

Your interpretation is in error. If a radio is type accepted to operate under one section of the regulations then modifying the radio to operate under a different section of the regulations invalidates the original type acceptance because the radio was not tested under the second set of requirements. It doesn't matter if the modification involved hardware and/or software. Any modification that causes the unit to operate outside its accepted parameters requires the radio to be resubmitted for type acceptance. The FCC Rules and Regulations require 7 volumes to contain them all. Reading one portion of one paragraph under one section does not negate the information or requirements found in the entire body of Title 47 of the US Code.

And since March of this year it has gone up to 16,138

No it is not. Simplex communication on those frequencies *is* illegal. It has been repeatedly explained to you. Sent from my SM-A125U using Tapatalk

Any changes to the type of emissions authorized would have to come from the Commision through either petition or upon self determination by a majority of the commissioners. In other words, don't hold your breath unless digital is allowed in Europe or several manufacturers petition the change.

No, the rule states THROUGH a repeater system. Units are limited to test transmissions only otherwise. Using an input frequency for simplex communications is not permitted.

I do not expect any performance impacts related to painting the cable. The RF signals travel on the inner surface of shield and outer surface of the center conductor. If by chance the paint had a metallic component, it would have a shielding effect and would be no different that running the coax in conduit, next to or within the metal channels of the vehicle. I can’t speak to the long-term adhesion though. Michael WRHS965 KE8PLM

I did that exact thing. I got my license, my personal radios for a little while. Now I have 40 watt Motorola repeater on on DB411 antenna with heliax hardline 120' agl on mountain. Great coverage. I'd say a very good start.

It has only been a few brief years since Midland and a tiny handful of others began using "channel numbers" instead of discrete frequencies or alpha name tags.

DB408 is my go to antenna for a tower site. I do run some DB404 but the 408 has a bit more gain. In NY winters they have lasted for years.

Its through APRS... For Winlink and FTM400 For APRS FOR SMSGATE
