In general we do loose hearing in the upper end of the audio spectrum as we age. Low frequency audio into the ear canal is a bit like VHF RF into a microwave waveguide. Energy transfer from outside t

Hi Alan, I think your idea of changing the characteristic of a single filter with some kind of switched in/out components has some merit. I would like to have more filter options in the 9MHz IF. I ha

Hi Bob, I have wondered if somehow RF could be getting into the Orion and affecting the reading, but I really haven't come up with a decent explanation. By the way, my antennas are distant and I use

Are these "spurs" images from the superheterodyne mixing scheme, or aliasing in the ADC/DSP system? There's a similar spur in the sub receiver as well, on the II (2.031). The subreceiver is prone tow

Hi Larry, The Paragon is a general coverage rig, and the Omni VI is not. Being general coverage requires wider bandpass filters in the receiver front end, given the same number of bands to cover 160

If you peruse the schematics of solid state RF PAs versus tube RF PAs, you will find the the bias control circuitry is the most complex part of the SS amp, often requiring more square inches of circu
