I wonder who their Chief Engineer is now? Maybe Finn Christiansen? Me I usually bump into a few of their ham types at the Communications Academy every year in Shoreline, WA. I will ask around this spring, April 2-3 I think it is this year. See www.commacademy.org for info. I have gone 2 years and consider it the best ham radio emergency communications training I have ever seen put together. Last year the Canadian hams from BC really did a super job on explaining problems and some solutions for forest fire communications support involving hams on scene in both countries. It was serious introspective critiquing, not the hype you see in the ham magazines. 73 Doug K7ABX |
My M710 predates the 2002 period. It was "opened" via a software
upload. Is it still Type Accepted? So far Bruce is either unwilling or ill-equipped to answer this simple question. Doug, k3qt s/v Callista "krj" wrote in message ... All Icom M710 transceivers mfg. since July 2002 are a type accepted marine transceiver that has the ham bands enabled by Icom. NO software uploads required. No "opening" of the radio required. It is legal for the Marine bands if you have a ships radio license and Restricted Radio operators license, and legal for the ham bands if you have a general or higher ham license. krj Bruce in Alaska wrote: In article , "Doug Dotson" dougdotson@NOSPAMcablespeedNOSPAMcom wrote: Not all that clear.

The software that is running in the radio, IS part of the Operational Interface, and if it is different than what was submitted to the FCC during the Type Acceptance Proceedure, and different than the software that was in the two submitted Representative Radios, then it is considered a MODIFICATION by the FCC and would incalidate the Type Acceptance of that radio when subsequently loaded in the radio by ANYONE, even the OEM. The Radio isn't the same, when the different software is loaded, unless that software was included in the Original, or Subsequent Type Acceptance Proceedure by the OEM. You can't modify the radio, in ANY substatial way after Type Acceptance has been granted, and still have that Type Acceptance be Valid. Bruce in alaska |

This is a case where no Modifications are made or needed, and Type Acceptance would still be VALID for this radio. Not the case for most other "Opened" radios. Bruce in alaska -- add a 2 before @ |

Hello Bruce,
You must be a lawyer! I suspect that Doug was not necessarily asking whether his older M710 is covered by the newer Type Acceptance Certificate. I think he was asking whether his older, open M710 is Type Accepted under *any* certificate. This gets all the more interesting since I believe Icom supplied the open M710s as an option and seemed to claim they were type-accepted. It is true that third parties and owners also opened some M710s and it is an entirely different question whether that invalidated the type acceptance. Let's stick with the M710s that Icom sold as open first. I understand your assertion that IF the early M710s were not type-accepted in an open version, THEN the type acceptance could be invalidated even if Icom opened them itself. What has NOT been established is that there was in fact no type acceptance of the early open versions. Can any of your contacts shed any light on that question? Thanks!

Interesting. So my ICOM radio that was modified via an ICOM upgrade
is no longer Type Accepted and is thus illegal. Must be alot of illegal radios out there. Doug "Bruce in Alaska" wrote in message ...
