Re: MARS mod on TX500
Other than that my only real gripes about the radio is not being able to listen to some other broadcasts with USB or LSB option selectable, it would be nice if there was a way to change that in the

Re: MARS mod on TX500
Good info. Yeah I don¡¯t think there¡¯s a point sending it in for a +/- 1Mhz mod that voids your warranty and that is hard on the radio on top of it. I don¡¯t want to fry it either. Maybe I just

Re: MARS mod on TX500
Thanks for the tip, I was looking into getting a G90, it looks like a fun radio, potentially the 891 as well. I just hate the idea of the TX500 frying just because I'm listening to an HF broadcast, go

Re: MARS mod on TX500

Re: MARS mod on TX500
About a year ago, I spoke with John who provides the U.S. service on these. He explained the TX-500 uses bandpass filters and deviating too far from the ham bands results in transmitting ¡°into¡±

Re: MARS mod on TX500
Understandable. I have modded my 7300, 891 and G90. The G90 is painfully easy to do, really. They¡¯ve even painted an arrow on the board to show which resistor to remove. No nearby neighbors you can

Re: MARS mod on TX500
A note to all regarding the MARS mod, it is a violation of FCC rules for someone not authorized to operate on MARS freqs to own a radio so modified. For that matter, it is also a violation to sell a

Re: MARS mod on TX500
I think the MARs mod is hardware based, which is why we probably have to send it in for 30 bucks plus shipping. It would be nice if it was a software update. Which radios did you mod to get the full

Re: MARS mod on TX500
Oh you mean opening up freqs could possibly be a software only matter? That would be great but also a first: All three HF radios I¡¯ve modded so far were a soldering job. Two needed a resistor

Re: MARS mod on TX500
No I appreciate the info John! Yes the CB was a firmware update so I would think Mars would be software to. On other radios it¡¯s really just removing a diode or two. If they are having you send it
