I've talked with many hams that assume they have some duty to pop up on public safety frequencies. No amount of logic will change their mind.


BUT,BUT,BUT 97.405



"§ 97.405 Station in distress.

(a) No provision of these rules prevents the use by an amateur station in distress of any means at its disposal to attract attention, make known its condition and location, and obtain assistance.

(b) No provision of these rules prevents the use by a station, in the exceptional circumstances described in paragraph (a) of this section, of any means of radiocommunications at its disposal to assist a station in distress."

See, it gives me authorization to do what ever I want, when ever I want.

And this was all written before the invention of the CELL PHONE.
To most like me and I used a HAM RADIO on a 2 meter HAM REPEATER to summon help when no other option was available 40 years before I was a HAM. That is and was the true meaning of the LAW MOST USE JUST TO TALK ON PUBLIC SERVICE FREQUENCIES.

Let’s not forget that some radios need to be mars modded to use 60 meters
Amateur radio in the U.S. has had privileges on the 60m channels since 2003. It's hard for me to imagine that there have been many radios brought to the amateur radio market in the past 19 years that haven't been capable of transmitting on the assigned 60m channels without modification. Yes, I understand that there may be many older radios in use that require modification to transmit on 60m.

I wonder if there might be some lack of knowledge at work here. I routinely see people online complaining that new Icoms don't have 60m capability. They make this false assumption because there's no 60m button on the radio. Like the Yaesu's you mention, the radios can, in fact, transmit on 60m and if you want easy access to the 60m channels, you can program them into memory. I just checked two of my later-model Icoms and they can transmit from 5.255 to 5.405 MHz without modification...no "MARS mod" needed.

Twice in the past week, I've seen current-model Icoms advertised for sale complete with photos that show the radios tuned to CB channels. Gee, you suppose these radios have been modified and are capable of transmitting on frequencies not assigned to amateur radio? You s'pose the owners swear by §97.405? Or, is it a case of "it's my radio, I'll do whatever I want with it"?

Ah yes, the ability of Part 97 to magically grant permissions on spectrum used by other services even though Part 2 is clearly the hierarchical portion of Title 47 that would allow that...

Absolutely. Hand your radio to the Deputy, then come in and complete an affidavit as to why you felt there was no other means of obtaining assistance. Someone will go through it and determine whether there genuinely wasn't any other way, etc. And, someone like a judge may determine if your exceptional circumstances were valid.

Nothing in 97.405 implies action without consequence.

But those 60 meter frequencies are primary to other users, so their use by amateurs (which used to be limited to voice, but now includes digital modes) is at the pleasure of the NTIA. That's why you may find MARS stations coming up on those frequencies during COMEXs and asking amateurs for local information that they were tasked to collect and aggregate. They can be used for routine amateur stuff, but at some point, an external (who is more than likely a ham, anyway, but wouldn't be representing amateur radio at that point in time) may come up on frequency and their call sign won't be in QRZ. It can be a liaison band.

The big selling point of 60 meters was the propagation difference between 75 and 40 meters for domestic emergencies (hence the impositions on power, antenna gain, and emissions). The intent was to have an avenue for infrastructure-independent NVIS communication into and out of an affected area, as most organizations with HF capabilities have and use other frequencies in the band.

Every LE agency is different, but if one tries this in my State, they will laugh at the attempt and inform that person to seek out an attorney for their own civil process.

That would be the Federal Communications Commission.

The group that will judge the unlicensed access to that portion of the RF spectrum for notification of an emergency will be the Enforcement Bureau of the FCC.

Absolutely not, all my HF radios are modified to use under my NTIA license to support the US Coast Guard on specific HF freqs outside the amateur bands and for CB. I also have a couple of Harris military radios that are wide open from the factory and perfectly legal to use on the amateur bands. Even the big amateur radio station at W1AW had or still has a wide open Harris commercial radio used on the amateur bands. Are they operating illegal?

MARS mods are nothing but an excuse to modify equipment to operate illegally on the CB band or elsewhere.

I visited W1AW in September. I recall seeing the Harris, but I don't think it's in regular service though it may be held in standby for some future event that requires its capabilities.

I drove by W1AW a couple of years ago but didn't have time in my schedule to stop by. I think the bottom line here is if you have a wide band radio from Harris or modified your IC-7300 for out of band operation, then paraded around your local FCC office with the radio, nothing would happen. They will not take the radio, they will not fine you, nothing. I kind of remember someone asking this of Riley Hollingsworth once, maybe at a Dayton Hamster convention and he said in effect, the FCC doesn't care unless you actually operate out of band.

Not if you're charged with obstructing or interfering with government operation under whatever local statutes there are. The FCC is inconsequential at that point. They can join in, or the case can be referred for additional charges. Without turning into an outhouse lawyer, this isn't enforcing rules under the FCC's purview.

Now, you might be right. Like I said, I'm not an outhouse lawyer like some folks who cite 90.405 or the other similar rules, but whatever happens will cost money to retain an attorney, pay for court costs, bail if one was taken into custody, and so on. Just avoid it. You can be right, and you can be wrong all at the same time. The people who use and operate those systems absolutely do not want anyone else on them. That said, if one does do that, the burden of proof will be on them.

I haven't been there since 2018, but they, in W1AW, and all the staffers at HQ were very gracious to me. I don't recall seeing a Harris in there, but there was a Rhode and Schwarz professional grade HF transceiver. They did show me some deployable HF setups in shippable boxes that they were making at the time to help support disaster operations in a similar manner that other NGOs with emergency operations responsibilities do. The Harris and R&S may have been for MARS, CAP, USCG, or SHARES operation when an authorized operator is present. They're diligent about proofing guests' licenses before letting them go on the air. My takeaway was they are taking the ESF-2 role more seriously now with the retention of a professional emergency manager on staff, and they're in a good position to be a liaison whenever necessary. I think it's a good step forward for the organization.1671799487344.png

Its amazing to me that this subject gets such constant attention.

What I take away from this discussion is-- its not that a radio can operate outside the official ham bands; its that, heaven help us all-- there are radios that are limited to only the ham bands-- and its those radios fall prey to the hackers.
Hackers can't resist the temptation to open them up and operate illegally-- its not their fault; the radios made them do it.
(Sarcasm :giggle:)

No one seems to get their panties in a wad over radios like say, the Harris transceivers. Is it because they come from the factory already 'open?'

And the Harris is just one example
A quick one minute search of Icom marine radios gave me this:

"The M803 is the long range digital communication radio for any cruiser. "
"Reach both marine and ham frequencies with the Class E DSC MF/HF certification."

( M803 Single Side Band (SSB) - Features - Icom America )

Do some folks get into a lather at the thought that a radio that is not constrained must therefore be destined for something nefarious?

...........................................................Grow up, People !

Maybe these are the cowboys that project onto others what they would/are doing themselves..... something all too common these days.

Merry Christmas !

Nefarious? I don't know. But, when I see a radio that was originally sold for amateur radio use listed for sale online with a photo that shows the radio tuned outside the amateur radio bands and/or the seller lists "MARS mod" or "modded" as a feature, then I get suspicious of how the radio has been used.

Newer radios usually require removal or repositioning of a very small surface-mount resistor to implement the mod. Watch some videos of these mods being applied and you see some gross soldering skills or diagonal cutters being used. If I'm going to spend several hundred dollars on a used radio, do I want one that has been poked with the infamous "golden screwdriver"?
