Hello everyone reading this post,
I have a quick question, i purchased a used IC-706 original version upon upgrading to General, since my upgrade a purchased a Icom IC-740 with plans to put the 706 mobile (which probbalby will not happen).
I am extremely happy with the 740's performace and want to keep as main rig.
My question is should i sell the 706 which is not being used and purchase a HF amp like the AL-811H ?
I have been happy with my signal reports using the 740, should i keep the 706 because of the age of the 740 ?
When connecting a amp like the AL-811H, is there anything i need to be aware of like interface ?
Don't have enough money to purchase amp and keep both radios.
Any suggestions would be greatly appriciated and i understand it is mostly preferance.
Thanks for helping a newer HF person out.
Thanks and 73's
Brian

Hi Brian,

Buy a dictionary!

But to get on to more serious issues, the IC-740's a nice rig (I had two of them in the early 1980s when they were new) and will outperform the IC-706 in many ways, provided you can keep it running.  However, it does indeed require a keying interface for the AL-811H or almost any amplifier, as its key line output can only source a few milliamps.  I used my 740's with Henry amps mostly, back in the early 80's, and I had to use an outboard keying interface that I homebrewed.  Since then, I see Ameritron, Harbach and others are selling essentially the same thing for about $30-$40, and that's not a bad deal.

Good luck with the 740!
