Jay, have you modified the Zachtek rig in some way? The documentation online may be outdated, but it doesn't list 22 m as an option. For those not familiar, it says that you pick a band to use, and then the transmitter selects a new frequency at random within the WSPR segment for each transmission in that band. (That's the only downside I can find about the Zachtek. Frequency hopping is potentially rude behavior in a band that largely consists of conventional beacons that were there first, and is definitely disruptive to propagation studies. Did the band suddenly close, or did a number of stations just randomly pick the same operating frequency in a given time slot? No way to tell.) If 22 m is available as a band option now, that'd be good to know. If selection of individual operating frequencies is possible, other than in plain signal generator mode, that'd be even better. Please advise.
