Effect of temperature on Radio Components
As far as radio performance goes, temperature has a measurable effect on receiver performance.  A receiver is rated for a certain sensitivity, and if thermal noise exceeds it, you have a reduction in signal-noise ratio as thermal noise contributes to the overall noise floor.  Thermal noise power is calculated in dBm/Hz by the formula 10Log_10(kTB*10^3) where k is Boltzmann's constant (1.3803*10^-23), T is temperature in Kelvin, and B is bandwidth in Hz.  At room temperature with a receive bandwidth of 1 Hz, thermal noise is usually about -174 dBm/Hz.  To see the effect on a receiver, you need to subtract thermal noise from your receive signal level (RSL).  This gives you your SNR.  All of these will change at any given time due to bandwidth, frequency, temperature, and a myriad of other variables, so it is beneficial to learn the calculations and put them in a spreadsheet to make quick use of them when you need them.
