N3LEE 12W "Portable" 900 mhz HAM RADIO

This is a 900 mhz Low-Power (12W) Motorola GTX radio attached to a 7ah SLA battery, and a cheap 900 mhz ISM band antenna (industrial 900 mhz applications). A quick QSO to prove our programming is correct was in order, so I figured I'd make a quick video of the setup. This makes for an ultra-powerful 900 mhz PORTABLE RADIO! Note: Repeater being used is actually 16 miles away on an unclear path! It should be noted that the N3HFK (Hopkinton, MA) repeater is configured with HEARCLEAR is OFF.

Do you have an adapter for the antenna or is that antenna mini uhf? I would like to see some programing videos for the GTX and if you had it for the Maxtrac as well. What antenna do you use on your mobile? Good video I have several radios and would love to build a repeater for 900. 73 KR8U

That antenna has an N-male connector. I'm using a metallic Mini-UHF to N-Female connector with the antenna threaded directly onto that adapter in this video. I'll see what I can do regarding programming videos for the GTX's, I have a few more radios to program soon! I use a PCTEL 5dBd gain antenna (8dbi) on an NMO mount in the mobile. I'll shoot some video of that, too. 73's de N3LEE

I'm positive it's the 12W. the 30W version is a lot deeper. All MCS2000's have a large heatsink surface similar to the CDM and XTL series mobile radios...

Got it for $10 at a flea market! I will post the model number the next time i see it...

STOP YOUR FRYING YOUR BRAIN MAN !

THERE IS A REASON THERE IS A 4 WATT RF LIMIT ON PORTABLE RADIOS !

lol. Looks like something I"d do. :)

2m around my home QTH has too many ears so a few of us have migrated over to the 23cm band and I personally LOVE 900mhz. Have 4 radios personally, can operate mobile, base, and portable.  Even put up a 19db yagi for the shack.. I LOL everytime I look up and see the 8 FOOT Long boom with the 8" elements. :)

73s!

@n3lee Do these radios light up on the back at night and are they anygood?

[MooseBaker]

I have a hand held Motorola GTX 900 mhz, would it communicate with your radio in this video?

[toddatron]

cool...! I brought my 1/4 watt FM transmitter to Japan hope I don't get arrested. Goes about 1/4 mile maybe less. Cheers!
