I bought a Racal R-2320/URR receiver (RA6703A-6) at Dayton. So today I

downloaded the manual from BAMA and read a few puzzling things -

"Receiver designed to provide reception capabilities for CW, AM,

LSB/USB, FM,and ISB, emissions over the frequency range of 0.5 Hz to

30 MHz."

*** 0.5 Hz**** Wow!

"Input signals from the antenna are connected to a low pass filter

which rejects signals

above 30 Hz."

****rejects everything above 30 Hz***  How's that gonna work out?

"Frequency Range 0.5 kHz to 29.999999 MHz"

****500 Hz ??****

Don't know whether that was in the original manual or a scanning

artifact but I am hoping that the range really is 0.5 MHz to 30 MHz.

If the rest of the manual is that careless about Hz, kHz, and MHz,

then troubleshooting is gonna be fun when I don't know if a mixer

signal should be at 49 Hz, 49 kHz, or 49 MHz....
