Hello Len! > Is this the same DSP unit designed by Lyle Johnson, KK7P and described on > his web page? Will the new Temp Comp circuit board interfere with > installation of the DSP board? (It is a bit taller than the original > resistor pack...). The field testing that is underway with the DSP unit has verified that the PLL mod fits just fine along with the DSP. 73, Lyle kK7P
