How to readily determine if a radio has MARS mod?	Reply

I did a search of eHam and the web, but did not find how to readily determine if a radio (ICOM 735) has the MARS mod accomplished? Thanks, Vince

Connect it to a dummy load and try to transmit outside of one of the ham bands, specifically one of the MARS frequencies. If it transmits, it's been modified; if it doesn't, it hasn't.

A previous ham suggested trying to transmit outside of normal ham bands. Try above 4.2 mhz. It it transmits, it has been modified, if not, it has not been modified. I am member of Air Force MARS, AFA2QB in Region 2, WV to FL. I'm in WV. There are verious mods for each brand and model of transceiver out there. I use Icom 725 and 756 Pro 3 myself, and the 725 is cutting one wire inside, and the 756 Pro 3 is removing 3 small stamp diods on a board with a pencil soldering iron. The Ameritron AL-1500 amplifier is cutting one green wire inside. Not too difficult. All these can be found on the internet. I posted the AL-1500 to eHam.net myself, along with 3-4 other Ameritron models. I am on Air Force MARS every night, and Net Control 1 night per week. 73's

All of them will handle out-of-ham-band signals without any modification other than a (possible) slight retuning of the input coils for minimum input SWR. The "green Wire" mod you refer to is to enable 10-12m operation. It has nothing to do with MARS usage.

You will note that the original poster has not bothered, even after three weeks, to come back and thank anyone for their information. :( Lon - NNN0OOR (Former MDE SMD, Deputy SMD, Assistant For Net Operations) Southern New England Navy-Marine Corps MARS Proudly Serving Those Who Serve

Apologies for not circling back to say thanks. The reason for the question was one of curiosity regarding the radio which I obtained from another ham awhile back. It appears the radio does in fact have MARS capability. Thanks! Vince

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? This brings up an interesting question, will this create a problem on the "out of band" segments? I know of way to many hams who just "spin the dial" and talk, if it dos not transmit, they know they are out of band. With the opening up of the radios I can see more issues of out of band transmissions, it is way to easy to do so. any thoughts?

I always look for the MARS Cap. My Wife knit one for my radio.
