NO.

Worked for a big city police department for nearly 26 years.  Worked on

radios and the radar systems.

If there was any way RF cold have incluenced the radar gun, some bottom-

feeding, slime-eating sleasy lawyer would have figgered it out by now.

Were you speeding?

the radio cause a bad reading on the radar? af4ob

WELL.....
 
 
probably not , most Portable type radar guns operate in the k band and by  
the time any harmonics for either 2 m or hf  enter the k band they are  either 
non existence or so weak as to be zip.  most of those guns are well  tested, 
and documented, so slow down is the only way to avoid a chance to buy  your own 
stop sign.
 
Also the Mythbusters did a segment on radar guns and tinfoil in the  hubcaps, 
and hanging cd's in the window and radar absorbing paint and other  things 
and nuttin did any thing..
 
 
 
info from the web on a google, 
 
k band...
 
This came into use in 1976-8 firstly for mobile units and uses 24.150 plus  
or minus 100 MHz (to give 24.050 to 24.250 GHz), or 24.125 plus or minus 100MHz 
 (to give 24.025 to 24.225 GHz). Because water will absorb wavelengths around 
 22.24 GHz it can be absorbed more easily by water in the atmosphere so a 
rainy  day may give a weaker signal. K Band can be detected anything upto 2 
miles 
away  on a good clear day. Traffic light sensors and some automatic door 
openers use K  Band transmitters so a false alarm may result when approaching 
these devices.  
Ka Band / Ka  WideBand
Came into force in 1983-7 and uses 34.2-35.2 GHz, Ka Wide  Band detection 
range is upto 1/2 mile. 
Ka Super Wide  Band
1992 Developed from Ka Wideband, Superwide Band can use any  frequency 
between 33.4-36.0 GHz. 
Ku Band
13.45 GHz Has  been tested in the UK and is used on the  continent.
