Have noticed a recent trend, whereby dispatch appears to be in the E mode.
To confirm, programmed a conventional analog scanner to the north repeater frequency. Received the telltale hash noise of E, and at the same no transmission on the P25 scanner. Subsequent reply transmissions were in the clear on the P25 scanner, and of course hash on the analog scanner as expected.
I've recently moved farther away from the park and at first thought it might be an antenna or performance issue. But then recalled that about 10 years ago it was fairly common to have E on dispatch. Had a Whistler scanner at that time and it produced a busy signal when the big E was present, making it easy to know what was what.
