Guest guest Posted November 3, 2007 Report Share Posted November 3, 2007 I pulled this from my post on the rifeforum, I thought people on this group might be interested. Here I go again. Sorry. This is a good explanation of Superregeneration. http://www.amalgamate2000.com/radio-hobbies/radio/Super-regen.htm Caution there is some kind of add on this page. Here are a couple quotes that makes it real interesting. " I tend think of the operation of a super-regenerative receiver as a regenerative receiver operating in a " sampling mode " Someone ( i.e. the RC circuit or outboard quench circuit) is tweaking the regeneration control up and down at an ultrasonic rate " " The next test was obvious ,how far is it transmitting? Well I put the maxon microphone on vox mode,on top of the Broadcast radio speaker, switched everything on, jumped in the car, tuned the ICOM 706 to 49.890 MHz and there it was!! clear as a bell,(also in about 3 other places either side of the carrier due to mixing of the quenching frequency sidebands " Now go here. http://www.eix.co.uk/Articles/Radio/Welcome.htm Can't give exact quote from this page,but here goes. The receiver reradiates and acts as a pulsed Rf transmitter. It creates narrow bursts of RF modulated at the quench repetition frequency. Also on this page you will notice exponentil positive self-oscillations, which may explain on the lab video the seemingly reversed exponential decay pulses, it would seem that they are not exponential decay but exponential growth pulses. The quench frequency is probably where the audio Crane/Beamray MOR's come from, of course these are not in the ultrasonic range, but 10x Beamray is. Also from my other readings the quench frequency does not have to be ultrasonic it can be in the audible range. It would seem that the AZ58 and Beamray devices were trying to emulate this by AM modulation of a carrier. How 1604Kc might fit into this not quite sure.perhaps the 1604KC is a difference frequency between the quenching frequency sidebands and the main frequency, at a specific quenching frequency. The above papers on superregeneration seem to explain the use of the Kennedy receivers. It might be prudent, to re-think Rife and Super-Regeneration. I dont pretend to understand all of this, but the hams/EE's here should be able to explain this in terms of Rife for the rest of us Beamray Quote Link to comment Share on other sites More sharing options...
