Bob, Thank you for the quick response, and important details regarding SVN 671. I would hate to see Flexradio inundated with many requests for repairs from the Firebox user's community. I will migrate to an earlier version. Considering that there are loud pops when transitioning from transmit to receive in V1.6.1 & V1.6.2, could the same damaging results be encountered with these loads as well?
Thank you, Mike W5CUL -----Original Message----- From: Robert McGwier [mailto:[EMAIL PROTECTED] Sent: Sunday, September 10, 2006 3:08 PM To: W5CUL Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] svn 671 BEWARE. We are attempting to fix a problem with the switching. The new switching code has been checked in with arbitrary values for certain important parameters. If you are using a FIREBOX, do not use 671. Go to an earlier version (easy to do in TortoiseSVN). The spike you see can easily be large enough to fry U2, the QSD. DO NOT USE this code to transmit. As always, SVN code is user beware. Thus the note.
