[R-390] Low Sensitivity 8-16 Mhz

[Jim M.]

On bands between 8 and 16 mhz the hearing on this 390a goes down 
considerably.  Cal signal on other bands is about 50 dB, but on the 8-16 
band it is down to 20 dB.  I suspect something in the RF coil set for that 
8-16.  I went through the RF alignment procedures and it appears to align 
correctly but the signal levels are very low compared to other bands.  Any 
ideas?  Jim N4BE
