MURS Grandfathering Question

[Flatshovel]

In my research I have discovered that the MURS radio service calls for radios that are Part 95 certified. However I seen several website which mention that there are some radios that are Part 90 which are grandfathered in and were made prior to 2002. The problem comes in to play is I can't seem to find any official documentation or website information from the FCC stating that the radios are grandfathered in and legal for use on the MURS frequencys. The reason I ask this question and hope that someone might be able to share some light on the subject is that I own 2 different brand radios and wanted to know if they are so called grandfathered in for use on the MURS frequencys.

Can anyone share any info on the following two radios to see if they are legal? I would like to keep them, however I am considering selling them if they cannot meet the requirements and purchase a couple of units that are Part 95 certified.

Motorola BTX-128 FCC ID: AZ489FT3793
Maxon SP-100H FCC ID: F3JPIOV

Thanks,
Joe

Look up the FCC IDs on https://www.fcc.gov/general/fcc-id-search-page or https://fccid.io and find the authorization grant issue date.
It looks like both were Part 90 authorized before 2002.

Ok so that makes them legal is that correct? What documentation proves the grandfathering aspect part of it? Yes I have run both FCC id's and both were made well before 2002.

I was wrong again.

See eCFR — Code of Federal Regulations
Subpart E—TECHNICAL REGULATIONS
§95.603 (g) and
§95.655 (d)

The old rule from the 2002 edition CFR says:
§95.603 (g) Each Multi-Use Radio Service transmitter (a transmitter that operates or is intended to operate in the MURS) must be certified in accordance with §90.203 of this chapter.

The new rule doesn't mention part 90.

I don't know which older part 90 certified radios are legal for MURS. Your best bet is to aks the FCC about the two FCC IDs.

Before the fire I had a letter from the Houston field office that said my HT1000s were legal for use on MURS.

I was wrong. Neither of the FCC IDs you posted are Part 95 certified so they can't legally be used on MURS. They were certified before 11/2002 but not for Part 95.

To be MURS legal a radio must be certified for Part 95.

Some radios manufactured before 11/2002 were certified for both 95 and other rule parts and can operate on other frequencies.

The rule was changed so that current MRUS radios manufactured and certified after 11/2002 cannot be capable of operating on other frequencies so they can't be certified for anything but Part 95.

See eCFR — Code of Federal Regulations
Subpart E—TECHNICAL REGULATIONS
§95.603 (g) and
§95.655 (d)

He certification predates the service. There was no MURS service when the radios were certified, just a couple of dot frequencies.

The rules address grandfathered stations (which would be using grandfathered equipment) and requires that equipment still follow the technical standards.

1. MURS radio was established by the FCC in the fall of 2002. There was no Part 95J certification before then.

2. Part 95.603 (g) states: Each Multi-Use Radio Service transmitter (a transmitter that operates or is intended to operate in the MURS) must be certificated in accordance with subpart J of part 2 of this chapter, Provided however, that those radio units certificated as of November 12, 2002 need not be recertificated.

3. The statement above can only refer to equipment certificated in Part 90 (since there was no Part 95J certification before the fall of 2002, when the statement was written).

4. Both of the units you mentioned were certificated in Part 90 before November 12, 2002, and meet the emissions mask and power requirements, so they ARE legal to use for MURS, according to 95.603 (g).

Oops. I see W5PKY beat me to it!

Wanted to let everyone know that I did get a answer back from the FCC stating that the radios are in fact legal and are grandfatherd in.

Thank you for all the help! On this.
