The example below provides the expected trigger at HamAlert, but the presentation is poor, with all 3 callsigns in the trigger title:
W1AW,K3LR,DX1DX rather than:
3 callsigns
DX1DX, K3LR, W1AW
or
51 callsigns
AC4NK, AE6Z, AE8I, ...
This is particularly poorly presented as the callsign count within the trigger increases. It's particularly bad on a mobile device. Adding a space after the callsign separation comma fixes this issue (or only using a space for separation)
