My MFJ1788 works perfect.Good quality,easy tune.
280 countries.done with it

I have a 1788 on order from DX Eng - delivery not expected till Dec or Jan. But I am still debating the pros and cons of the 10 to 30 meter vs the 15 to 40 meter.

Very inefficient and very narrow on 40 but no phone on 30 so the 10 to 30 version is basically limited to 10 to 20 meters on phone. The 10-30 receives CB.

So what do you guys suggest between the 2 versions.? Why did you get one version instead of the other?
