Factory loaded frequency memories.


 

I recently saved a FT-857 from the trash pile and found that the radio appeared to have gone through hard and soft resets.? After programming in local repeaters, the radio seems to work fine. Searches on the Internet seem to indicate that there was a set of factory installed frequencies to set the guard bands on HF.? I'd like to return the radio back to "like new" condition and wonder if there is a list posted out there of the original frequencies.

Hi Bill,

In the past I've seen just restoring the factory jumpers on the main board for the country of use (eg. US, EU, DE, JA, etc) to remove the MARS Mod, and a reset put them back to new, out of box condition. The usual reason for needing to program anything is when the MARS mod is in and they want the channelized 5MHz frequencies. The MARS mod clears these presets. Some radio's will have 2-3 jumpers that would need to be put back depending on the LOT Number of the radio and the mod that was done. I'm on my 4th one personally and the first 2 were the same, the third and forth ones are each different than the first 2, revision changes I suppose.

I haven't seen a list for what you are wanting, only the 5MHz stuff. I do know Yaesu has on occasion replaced the serial eeprom when sent in for repairs.

Thanks Mitch!

It appears that the radio was untouched other than no frequency memories and menus at defaults.? From the articles I read on the Internet, the resets would clear the frequency memories and they had to be reloaded.? The term guard bands came into play so I assumed that there were factory frequencies and when it was reset, the previous owner thought he had rendered the radio useless and threw it away.? I should have realized that when I couldn't find a list that my understanding of the radio was flawed.
