From the radio itself, the only way to resolve this is to force a reset which will clear some of the settings and/or memory entries depending upon which reset is used. I believe I'm justified in calling this a small bug in the Yaesu firmware, because when the radio accesses the memory with the 0xFF padded label, it goes into a continual reboot cycle with lots of clicking of relays and a beep each time it restarts. Until a version later than 0.3.1 is released, you need to download a daily release. The current release of CHiRP, 0.3.1 from April 2013, has the old driver. The very next CHiRP build had the fixed version of the driver. Marco Filippi, IZ3GME the primary author of the FT-87 driver made the change within hours of me reporting the problem. I believe G4HFQ's FTbasicMMO, only space pads as well. The corrected version of CHiRP now space pads the label out to 8 characters. Padding with 0xFF for labels that are 5 characters or more doesn't seem to cause any issues. There is no way that I found, from the radio to create a memory label that wasn't space padded. When a label is created for a memory (channel) on the radio, it is set to 'CH-NNN '. An unused memory label defaults to eight bytes of 0xFF on the radio. The older versions of CHiRP were padding unused characters with 0xFF. The problem has to do with how the 8 character memory label is padded. This probably applies to the FT-897(d) as well. This blog post just archives the info in case someone else stumbles across the problem either by using an outdated version of CHiRP or writing their own software for manipulating the Yaesu FT-87 memory. I isolated the problem, the Yaesu FT-87 driver in CHiRP now works around the problem starting with daily builds around June 27th, 2013. I found a small latent problem in the Yaesu FT-857D firmware which could cause the radio to crash and go into a reboot loop when a 4 character or less label was created using the free CHiRP radio programming software.
