Re: hf radio modified marine or modified ham

Well for my 2 cents, I have an Icom 7200 for my HF side and a TM-D710E for my VHF/UHF both work really well for me, I was a Yeasu man for years but thought the 7200 looked better on board. Both work very well, as for antennas, I have a dual band on top of the mast for the VHF/UHF and use the back stay for HF (with a tuner) but have just bought a vertical HF antenna which is nearly 20ft long, which I shall have installed on the back stainless work. I am told (will believe it when I see it) that it covers 80m (3.5mhz) to 6m bands (50mhz) without gaps or needing a tuner. Anyway its worth a try and yes I do have all the needed paperwork to use both the Marine and the Ham bands.
The TM-D710E does contain its own GPS system and uses a system know as APRS which my local ham friends love to see when we out and about locally.
For what its worth thats my setup, excluding various other handhelds, and they work fine for me, infact my Ham station onboard is better than the one I have at home

Re: hf radio modified marine or modified ham

I see, I see. I suppose what turned me on to this originally was research on how much better a HAM is for the truck than a CB. So perhaps it is HAM + VHF + PLB or EPIRB lol....

Sounds like the same thing I went throught trying to combine GPS. In one day you could use a GPS in your truck, boat, and backpack all they all need their own... what else is new right?

Thank you for the input.

"if I wanted a low cost radio capable of "
Yeah, skip the big radio there's no such thing as a cheap one.

Buy a CB for the truck, a VHF for the boat, and a PLB to use in real emergencies wherever you happen to be, in case one of those doesn't get you help. All three of those combined will be cheaper than the option.

For a legal combination ham/ marine-ssb rig you'll pay a fast thousand bucks before you starting the installation. And it won't be terribly portable to fit most vehicles. And then of course, you'll need the licenses (ham, ships, ship operators) as well.

If you're trying to save money, then that's the best, cheapest and most legal way to do things. If you are in the US and break the laws they can, and will, fine you up to something like 10,000 US dollars for every breach of the law they find you have made.

By the way, in the US Hams CAN legally modify marine equipment to operate in the ham bands without any type acceptance or any of that stuff. In fact, hams can legally modify pretty much anything INTO the ham bands.

They can't modify it OUT of the ham bands.
This is a very informative thread!

So after reading it, if I wanted a low cost radio (under $500?) capable of Marine and HAM operation (and of course were to obtain a valid HAM license therefore) in the US, does anyone have any recommendations for a radio designed to operate in both bands?

I realize I am not the typical user of this forum, but my application would be for occaisonal use on my trailer boat (Marine of course) and occaisonal use in my truck (HAM of course for land based use on trail rides, hunting emergency communication, etc). My installation would have to be carefully considered for easy removal back and forth. If for reasons I haven't yet learned this is illogical or simply not cost effective, that's fine to point out as well.

I don't NEED a radio for either really, but like the idea for several reasons and feel I could more easily justify picking up the equipment, hobby, and knowledge if I could combine use cases.

Thanks for any input...

Triquetra I have been looking at getting an HF rig for my boat also, and I have found that the amateurs tend to prefer the amateur rigs and likewise for the marine users for the marine rigs. I have an amateur radio license, but I am currently leaning towards the marine rigs. I found that the marine rigs tend to be smaller (like the amateur portable models), but are focused on having memories and features for the marine user who likes to just have access to particular channels. Amateurs like to surf the bands, so their radios have more features for doing that. Most newer marine radios can sync with your GPS for DSC and other marine features like e-mail, lower power consumption, ease of stowing, and top on my list, water resistance (though some HAM rigs have this too).

As others mentioned you have to have licenses for using either of the HF band plans (marine and amateur). Getting access to an amateur (who likes to tinker with antennas) to help with your antenna to check the SWR and that you have a good ground plane would be beneficial, since on boats that is one of the major problems for getting good propagation (and every boat is different).

Good luck.

Only because the US was too shortsighted to take it as a war prize, like the Phillipines or Puerto Rico.

ffiill I do sometimes question what all the regulations are about worldwide.
The idiots of the world without registration or licencing are going to try to talk to fighter pilots or Jumbo jet pilots.
Its just that Icom seem to dominate the market place for marine hf despite the fact that it was probably a Yaesu hf radio that confirmed the sucessful raid on Pearl Harbour!
Sorry but I smell monopolistic practises.
Otherwise why did Yaesu in its early FT 757 make it so easy with a slide swtich to open up the radio? Or in later models jump leads and latterly a simple programme adjustment accessed through the programmimg sequences?
Was it hoping to have its ham radios authorised for marine use.
Likewise its Vertex open chanel tranceivers.
When here in the UK you have to pay 30% more for a marine legal Icom HF than in the US restrictive trading practises at least come to mind.
