Isn't that the truth! Can't understand why some guys need 337's for radios and some guys don't. I just updated the entire avionics package in the Bonanza and the IA first wanted to do 337's then not, then yes and I don't know what he wants now! I say, to be safe, have your guy do a 337. What they'll do is reference the STC from the manufacturer and make sure everything won't catch on fire when you press the mic button. There's nothing to putting a new style radio in. Calculate the draw, put in a new AN/MS circuit breaker with some nice wiring and let it fly! Good luck, and let us know about the Micro Air. ----- Original Message ----- From: "Glen Ward" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Friday, March 23, 2001 7:20 PM Subject: Re: [COUPERS-TECH] Approved Instruments (or not) > ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- > > Jan, you may be looking for trouble.
