nevermind... solved it 0.3dB insertion loss now... mike -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Mike Perryman Sent: Tuesday, November 22, 2005 12:51 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] tuning a TFB6024A low-pass filter
A question for the Micor Guru's of the group... I am in process of converting a low-band Micor to 6m and have a quick question.. the only docs I have found for tuning the low-pass filter to 6m meters is to tune for minimum insertion loss... What constitutes an acceptable value for insertion loss? I am not happy with the current -0.68dB to 0.7dB @ 51.9MHz figure I have obtained. And if I scroll the marker over to around 28MHz, I see it drops to around -0.4dB. Is it worth the trouble to optimize this filter? Or will the exciter generally make enough signal that I shouldn't worry about it and move on? It took a little twiddling to get it to this point.. but not opposed to continuing for better numbers.. Any takers on this one? Thanks, mike Yahoo! Groups Links Yahoo!
