The Gonset G76 also uses the 7360. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Thursday, November 06, 2003 1:37 PM To: amradio@mailman.qth.net Subject: Re: [AMRadio] FW: Homebrew receiver
Clegg Intercepter receiver for 6 and 2 meters also used the 7360 as a mixer. In my Squires Sanders SS-1R receiver, with no signals present and the antenna connected, the receiver is very quiet. It comes to life when you tune a signal. The receiver was not very tolerant of random length antennas or antennas that didn't provide a decent match to the frequencies you wanted to receive. The 7360 was also used as a balanced modulator in a number of 60's sweep tube SSB transceivers.
