dana's notes on hardware changes (.pdf)


Intro:

    s3046  used the sband transmitter to transmit two tones separated by a fixed spacing. It then used the 430 Mhz xmiter with the coded long pulse program to look for any enhancements in the plasma line (jun15, sep15)



Notes on running the 2 xmiters together

06jun16:

    During the day we tried to run the sband xmter with the hf heater.

During the evening we ran the sband transmitter.

Setup:

We used an SEE receiving system (paul bernhardt's located at cristiano's house is camuy) as well as the optical equipment in the photometer shack. The 430 transmitter was not used.'
