By what first hand knowledge do you know this? Yes, transmitting on a marine radio in close proximity to a garmin can overload the front end and damage it but by what experience are you claiming the preamp in and of itself will damage the garmin?
I would not use one myself but there is no evidence to support that a preamp will damage the garmin. [/B][/QUOTE]
I don't know much about radios and such. I was reading what a tech said on another forum that did know a lot about them. He was saying his was allready getting weak and was going to quit useing his and was asking Garmin to try and do something about makeing the new ones hold up better useing them on the new models. Garmin didn't deny the problem so I took it he knew what he was talking about. [/B][/QUOTE]
I see you got to my post before I deleted it! I read it again and felt it could be worded differently so I deleted it and was going to reword it. You must have been on the thread when I posted it because it was not up for over a few minutes. I apologize if it seemed confrontational because that was not my intent.
I have never seen a receiver get worse and worse over time because of front end overload. You typically blow out the portion of the receiver front end where the signal is first injected in the circuit when a radio is keyed up, or you may blow it later when a radio is keyed up if the front end is robust. Possibly, you may never damage it at all.
The reason Garmin did not deny it is because he probably talked to someone at the front desk who knows nothing about rf and merely answers the phone!
I guess I will not say it can't happen, but I have never seen it happen by merely using a preamp and I have been around this stuff for over 20 years. Someone may use a marine radio near their garmin and never have a problem and then put the preamp in line and then damage their garmin but I do not believe that would be the preamps fault. That person was living on the edge by using the marine radio near the garmin in the first place!
That guy on the other forum, was he using a radio in his truck or did he say?
I will inquire with some other minds on this issue and see what they say.
