Project TouCans: Rock Locked Station Operation

 Project TouCans is rock locked, meaning that it operates on a single frquency: 14057.4 kHz at teh moment. This leads to station operation that looks a bit different from most. Notice that while we do use the RBN , it's mostly as a wellness check for TouCans. For us to call a station, they have to be on frqueqncy, so we also use the tool shown in the terminal window to the left, rbn_telnet.py . We can start it with a signal range such as  python3 rbn_telnet.py -b 14057 -e 14059 The tool then connects to the RBN's telnet feed and filters for only calls between the -b and -e arguments in kHz.

Things I Learned: RBN availability

The Reverse Beacon Network website is down today (at this moment, 23/09/18 17:29 Z). And! The reverse beacon network telnet port is still up and running! It can be reached by typing  telnet telnet.reversebeacon.net 7000 Assuming you have telnet installed. Orrrrr a spiffy script that will look for the frequencies you're interested in. (Along with Python)

Things I Learned: The dB difference on RBN isn't the battery

Got the following data back from my rbn_telnet.py program this afternoon. It's not what the script was created for, but it's wound up being a nice use model: b'DX de VE6JY-#:   14057.5  KD0FNR         CW     5 dB  20 WPM  CQ      2254Z\r\n' b'DX de VE7CC-#:   14057.5  KD0FNR         CW     3 dB  21 WPM  CQ      2254Z\r\n' b'DX de W6BB-#:    14058.1  KD0FNR         CW     2 dB  21 WPM  CQ      2255Z\r\n' b'DX de VE6JY-#:   14058.1  KD0FNR         CW    10 dB  21 WPM  CQ      2255Z\r\n' Note that the same station, VE6JY has the rockmite coming in first at 5 dB on 14057.5 kHz at 2245Z and then at 10 dB one minute later on 14058.1. I had suspected there might be battery issues with...
