     Blogspot and Feedburner tell me that as of the end of August 2021, they
    will no longer be sending automatic e-mails to those who have subscribed to e-mail alerts for blog postings.  I believe you can still subscribe to the blog. But no more e-mailed alerts. Please let me know if this loss of automatic e-mails will cause major disruptions for
    you. soldersmoke@yahoo.com

    Adding Automatic Gain Control to the Termination Insensitive Amplifier

    Posted: 30 Aug 2021 03:34 AM PDT http://soldersmoke.blogspot.com/2021/08/adding-automatic-gain-control-to.html

     Earlier this month Paul VK3HN had a very interesting blog post about
    adding Automatic Gain Control to Termination Insensitive Amplifiers (TIAs).  Termination Insensitivity is especially important in bidirectional rigs.  The shape of the crystal filter bandpass response is very dependent
    on the impedances presented at both ends of the filter.  In bidirectional
    rigs you are changing the signal
