I am aware that AVR's had a problem of transmitting a signal at 121.5mhz but I have never heard of this problem in relation to a MAX & MEL EMU Board. Does anyone know if the EMU boards have the same problem?

I am currently using the internal MAX & MEL design from the M24C web site but I am also interested to know if the external MAX & MEL boards that use the card slot have this problem.


Here is a claim being made by someone on another site:

I tried emu a couple of years back with Winvu. I was quite happy until it became known that ALL the Dick emu boards emit a signal at 121.5 MHz when they are in the card slot. They don't even have to be plugged into the computer. I didn't believe it until I took out my own scanner and set it to 121.5 MHz (the AM aviation band emergency frequency .. the one the ELT transmitters use when there is a crash) and could detect my emu running from ACROSS THE STREET. It was transmitting strong enough for my scanner to pick it up at least 150 feet away. A small directional radio antenna (like you see animal trackers use) in a van going slowly down a street could nail down all the houses using this method. I didn't believe it until I saw it myself. Don't take my word for this. Borrow an aviation band scanner from a friend if you don't have one of your own, set it at 121.5 MHz and try it yourself. Emu board just has to be in a plugged in receiver. Computer does NOT have to be hooked up. This frequency just happens to be the one that is continuously monitored b y th authorities because it is used in ELT's which transmit a locator signal when a plane crashes. Yes, I tried aluminum foil around the receiver etc but could not bring it down to a level that I felt wouldn't be detectable from the street. Search on 121.5 on some of the other sites that specialize in dick

Wow, not very much of a response. I don't feel that I have an answer yet.
