Thanks Lee KD8QYM

Most have a separate control on the front panel or a selection from a menu. What radio are you referring to that requires you to remove the cover to adjust the mic gain? And yes you need to adjust the mic gain occasionally. Bill - WA0CBW ARRL Technical Coordinator - Kansas Section

I think having to remove the cover to adjust the mic gain might be a feature I wouldn't like. For the price however, it appears to be a good buy. This looks like a pretty good radio for a beginner. Not too complicated for your first HF experience. Having a remote head would be good if you are thinking about using it in a mobile. I would suggest you look at some of the reviews for this radio to see if there is anything else you might not like. I believe the "T" is an upgrade of the original model that was first released. So maybe any bugs in the original model have been taken care of. Good Luck on your first radio! Bill - WA0CBW ARRL Technical Coordinator - Kansas Section

This would make me look elsewhere for an HF radio. Not all microphones are created equal, and not all voices are the same. While after initial adjustment you may seldome want to adjust mic gain, I believe that mic gain adjustment needs to be accessable without removing the case. Most HF radios will have a mic gain knob, or allow the mic gain to be adjusted via a menu. I believe that this is a poor design choice by Alinco. A few hints here on choosing a radio. Get all the information that you can on the radios that you are interested in. Read reviews, download and read manuals, search on the internet for problems and solutions. I would try to join a local club and talk to other Hams. And feel free to ask questions here!
