[ARC5] S+N/N ratio results.

[Glen Zook]

I first learned the importance of using a 6 dB pad my junior year at Georgia Tech when I started working at the Motorola Service Station in Atlanta, Georgia, in April of 1965.  I was getting married in June and needed to have a full-time job as well as carrying a "full load" academically.  Have used a 6 dB pad on a signal generator ever since.

Motorola used to have a resistor kit for the 6 dB pads because it was pretty common for a bench technician to forget that the signal generator was still connected, instead of a wattmeter/dummy load, and key the transmitter.  That "let the smoke out of" the pad really fast!  Every two-way radio repair facility that I ever saw kept a number of these kits "in stock" to be used when the pad was destroyed.

While the cover accessories for the URM-25 are often missing there is plenty 
of Internet data on rolling your own.
Im glad to see more people on here are joining the 6dB pad bandwagon I 
mentioned in this thread a few days ago.
They are also beneficial and regularly used with modern radios and test 
equipment.
