Heads up. Just got a few of these radios and have found that in the 156.xxx range they knock the GPS receiver offline in the combine. Greenstar is nav etc equipment used in tractors and combines and planters etc . Have not had the time to do further testing. But if your in the tractor next to it..... your signal goes to zero or 10% for awhile. when it comes back, your combine might be off a few rows for awhile. This will effect calculations. Have not tried it with auto steer.....
I will try some other channels and UHF when I get a free moment and programing cable.

Interesting. Wonder what kind of Chinese smoke magic is going on in there to emit enough interference up at 1500Mhz? -- Teamwork is a lot of people doing what I say.

It is probably not emitting that high. I'd guess that the interference interaction is at a lower freq and in the Greenstar device since it is a passive listener...??

Yeah I thought about that yesterday afternoon after I posted. Maybe they both use the same freq LO? Mixer products?
Does it only occur when the handheld is nearby and powered up? When transmitting? Is it made of kryptonite and simply being in close proximity to another electronic device causes it to writhe in pain? -- Teamwork is a lot of people doing what I say.
reply to plk I had the same thing happen with a older AM.FM radio in a chevy truck and a Garmin GPS 45 (old GPS)...I think it was the local oscillator freq blocking..

I spoke to someone from John Deere the other day. He said they have seen it with other folks radio's to. It could be some poor RF shielding in the Green star gps receiver.
Only happens when I transmit within a few 100 feet
