Dail, You mean you did not get Bird 43 flue by opening it up and letting the air out into your enviorment. This gives me confidence, hi.
Yep at +/-5% of full scale the Bird is not very accurate. I think it is good for what we use it for. I also think because it is built strong it is popular although it don't handle being dropped from 1000 ft tower very well. Working to 1 Ghz when 1 G was magic also helped. Also the higher power capability. 73, ron, n9ee/r >From: Dail Terry <[EMAIL PROTECTED]> >Date: 2007/08/18 Sat PM 12:53:51 CDT >To: [email protected] >Subject: Re: Re: [Repeater-Builder] Bird Wattmeter X2/X5 Range Switch > >Hi All, > I did the X2/X5 Range Switch Modification on my Bird 43 about six months >ago.
