[DSP-10] Receiver system temperature

[kd7ts]

Hi Courtney,

You're getting into the features that make the DSP-10 a 
relly fun box.

I use the "tone" feature for quick peaking on sun noise, but 
it will work for what you're doing as well. Sensitivity is 
adjustable and the averaging is according to what you set up 
  in the menu box. It's something that is easier to use then 
explain. When the tone is steady, read the number ! It is 
taking many thousands of samples per second, so writing down 
a series of readings and averaging them, has already been 
done for you.

Can you use a third, or maybe fourth resistor to heat the 
two that make up the termination ? Wrap the whole package in 
something that isn't combustible and has some thermal 
insulating properties.

Y factor is an easier calculation if your test results are 
in noise power (DB). The bandwidth of the DSP-10 is very 
well defined, and when you use the noise settings of the 
"tone", you are using the total bandwidth. There are some 
neat spreadsheet programs that do this, and I think Paul 
Wades HDLANT program has Y factor as a menu choice.

I use my DSP-10 as an IF for higher bands, and have never 
checked its NF. From the parts used, I would hope it is 
around 4 to 5 db.
