Thanks to many folks, especially K8YSE and KE4KOL, it looks like we may have scared off whomever was squatting on the 880 uplink. Starting this afternoon we will give it another try, 145.880 up, and 435.150 down. This was the most common uplink historically with this downlink, so I'd like for it to be the default in these post-battery failure operations.
