[chirp_users] FT8800R problem when overwriting previously stored out of band frequencies
I recently obtained a used Yaesu FT-8800R that had been used by a Ham that was involved in CERT and other public services. He was also a police officer and had lots of local municipal frequencies stored. I read the radio, then overwrote any out of band entries with local 2M or 440 MHz repeaters. Any changed entries previously in those ham bands worked fine (except for the skip feature being ignored).
All of the entries in the 138 MHz range, that I overwrote with repeater frequencies, did not receive properly. The display showed the correct info but the receive was garbled. If I entered the same info manually, that memory location then received properly. I was wondering if CHIRP fails to change some mode setting such as AM?

Hmm, does the radio indicate that it's in AM mode?
You might try deleting the memories and then re-editing them. Just editing the memory will make chirp try to tiptoe around all of the settings it doesn't know about. If you do a delete operation (so that it shows 0.000MHz in grey) it should wipe the entire memory channel and start fresh. That'd be my first step.
Thanks for the quick reply.
The FT-8800 manual only devotes a couple of lines to the general coverage receiver. Basically, it says that the radio will scan 108 up to 999, skipping cellular. It doesn't appear that the screen shows AM/FM mode; however, Menu item 46 toggles AM Mode on and off.
I was pretty sure that the issue was the mode setting. I had just programmed the radio in South Fl for a trip up to Lake City in North Fl. I had overwritten an aircraft band entry with the 146.94 repeater up there. On the trip up, scan would open the squelch frequently with static generated by cars in close proximity. I was able to pull up the repeater so the offset and PL set correctly. As soon as I discovered the garbled receive problem and re-entered the info into memory the interference issue was solved.
The previous owner used G4FHQ programming software. In hind sight I should have done a master reset since he couldn't explain the hyper memory settings or what was stored. I hope you fix the Skip feature. I'd like to wait until that works to give CHIRP another try.
Thanks,
