Copied from FRN post:
it has come to my immediate attention that a KIPM relay/clone will be on transmitting from the desert s.west tonight PDT saturday - 7 p.m. PDT - (0200 UT sunday) on 6975 USB with KIPM shows. repeats on sunday morning beg 0700 PDT / 1400 UT sunday. 6975 kHz USB. 73
ML
and...
Specifications of KIPM relay - dipole facing n.w./s.e.; 100 watts USB. should have a reception pattern over s.w. and western USA and maybe Plains if skip and QRN permit. 73 ML
For the curious, KIPM reference may be found on HF Underground wiki and elsewhere on the web.
(Note: Some listeners may hear QRM from Israeli based Galei Zahal on 6973 AM, which is not a pirate.)
