Beg, borrow or steal and HP 8640B sig gen. It'll go down to about a 0.013
microvolts (-145dB) and you'll find the floor for each long bvefore you

Hello all,
After recapping and aligning both my 28A and my 42, I did a side by
side
comparison. Is it my imagination or is the 28A more sensitive on the
frequencies that rcvrs both cover? 73Mike KF6KXG
