Ever since I had a problem after converting my KT34XA to a KT36XA, I have been 
collecting KT34XA/KT36XA element resonant frequency data from various sources. 
The results (which now include K1KP's data) can be downloaded from: .

My measurement technique was to remove each element from the boom and suspend 
about 15 feet off the ground. For each element, I opened up the center straps 
that it looked like a center-fed dipole. For the driven elements, I removed the 
balun. I connected a Palomar noise bridge mounted at the center of each element 
with lead lengths as short as possible. I tuned to the frequency that the 
reactive component was 0.

As to your 15 meter problem, I would recommend adjusting the reflector 
dimensions to bring the resonant frequency down below the band.
