MC1350 appnote.
"ian field" wrote in message ... Is there an appnote for the MC1350? TIA. I used it in my Yaisu FT-101 35 years ago as a Rf compressor. The Yaisu generated the SSB signal around 3 Mhz. I ended up replacing the final tubes with industrial 6146s (6080 I think). The sweep tubes couldn't take the increase in average power. Everyone thought I was running a 2KW linear when I switched the compressor on. Here is one data sheet http://www.hamradioindia.com/datasheets/mc1350.pdf -- A man is known by the company he keeps- Unknown Anyolmouse |

Since I now have so many, I thought maybe I should try to do something with them. My first thought was an audio compressor. FWIF, about the same time I used the MC1350P for an RF SSB compressor an article was published in one of the ham radio magazines showing how to build an outboard audio compressor using the MC1350P. In order to get it to work the author modulated an RF signal and compressed the RF and then demodulated the RF signal and applied the resulting compressed audio into the microphone jack. I found it much easier to compress the transceiver's SSB modulated signal and then making sure the signal was amplified linearly after it was compressed. The chip was designed for RF applications in TV IFs, not audio. -- We have met the enemy and he is us-- Pogo Anyolmouse |
