I suspect CQ will be healthy for the next several years. It was obvious that the advertising and subs for Pop'Comm and CQ VHF weren't paying their way. I'm sure they did their best to keep the other two mags in print, but in the end economics won out. Taking the less than profitable mags to digital was probably a wise, but sad, move. If they failed, it was because they didn't have enough subscribers, nor enough advertisements from suppliers/manufacturers. Don't complain about ads in a magazine. They make them profitable. 50% ads to articles is a good ratio. Very few mags can do it.
