Did P&H ever produce the 10-80M one for the A4? I thought it died in the lab 
because of spurs. I built one to use the A4 to drive a CE 10B on 20M which 
drove a HB 6M transverter built into a NCX-A case around 66-67. I didnt have 
a SA to see how bad the spurs were.

The HT-32/SX-115 should be fairly simple as they use the same VFO.
