<< I think MOST radios these days are moded in one form or another. With the advent of the 60 meter band, MARS mods have become the mod of choice. Is there such a thing as an off the shelf radio that does NOT have a mod done to it? >> I'm willing to be the majority of HF rigs have NOT been modified for out-of-ham-band-operation. The number of hams actually using 60m is rather small, as is the actual number of MARS members. As for those who mod their rigs to enable out-of-band operation, if they're too lazy or incompetent to pay attention to where they are transmitting, they deserve anything the FCC does to them for such operation.

Actually there are radios that do not have "out of band" modifications for MARS but work on 60 meters. My Tentec jupiter is an example. I assume that if needed I could probably get the firmware update to use it on MARS frequencies. I used to be in Navy MARS about 25 years ago. Are MARSgrams and message handling still done on the voice nets? I was digging through some papers here and found that I have a pad of the old MARSgram forms. Brought back memories... ages ago I was NNN0ZUH. 73 de w8nsi jim

Jim: That's a possibility, but you would have to ask TenTec to be sure. Things have changed a little since you were in Navy MARS. With rare exceptions, MARSGrams and phone patches are pretty much a thing in the past, as is MARS traffic to ships afloat. The primary mission of all three MARS services is now ECOM support to the Department of Defense, state governments, local governments and certain NGOs, in that order. This year a tri-service SOP for voice nets was adopted and replaces the different procedures used by the three services. All the bugs haven't been worked out, but we are getting there. :) Interoperability between services is now common, as is participation in each other's nets and joint ECOM exercises. Most traffic is now passed digitally, even on voice nets. About the only things passed by voice any more are net reports, and not many of them. While RTTY and AMTOR are still used, MT63 is fast becoming the mode of choice for passing traffic at the local level. MT63 at 2k runs about five times as fast as RTTY and AMTOR. It works well, even under very weak signal conditions. Navy MARS' MDS (MARS Data System) is being replaced with WinLink 2000. I hope this is helpful information.
