I'm going to assume by the callsigns that this is in fact a military net. I thought they were out of band hams at first, then a pirate. Nope! The callsigns rather told the tale. Here's my log.
7433, MARS net, 2320-2328. AAR5VY, AAM5EMI, and an AAV station talking about the encoding of e-mail addresses real and fictitious. Signal good at peaks, variable depending on the speaker, best when AAR5VY spoke up. Heard in USB. SIO 434.
