Solid combo. I have the 857. May want to pick up the programming/cat cable for the 450 so you can use your computer to change stations/freqs if you choose.

ARRL members can download a 4 part series of articles published in QST during 1986 called "Electromagnetic Pulse and the Radio Amateur". Part two is available to anyone but I think you have to be logged in to download 1, 3 and 4. Part 4 gets to the meat of things with specific recommendations and diagrams on protecting a station.

One question though. I'm able to run splits pretty well but I don't understand when they say they're "listening up 5 to 10". I can usually get them using up 5 but how do they listen to a 5Khz range? Do some radios have some kind of capability I'm not familiar with?
It pains me to say this but.... I don't get it. ???
OK, lets set this up: For the sake of discussion let's say he's on 14.020, listening up 5 to 10.
That means his transmitter is parked right dead on 14.020 and it never moves from there, everybody calling will have their receiver parked right dead on 14.020 also (sort of).
To listen for calls he is tuning his receiver from 14.025 up through 14.030 until he hears one that he wants. Lets say he hears someone at 14.026 and makes contact with him then clears with that person. Chances are there are others also calling him on 14.026 so say he answers one or two more at that frequency. Eventually the wolf pack starts getting wise to the fact that he's listening on 14.026 and more start calling there, increasing the QRM so he tunes his receiver up to say 14.027 where there are fewer callers and he can better hear.
This cycle just keeps repeating within the range of 14.025 through 14.030. This is all done to spread out the pile up to better manage it.
Now you could just park your transmitter and receiver frequencies in one spot and just blindly call over and over in hopes that he happens to be listening to that particular frequency and that he happens to pick your call out at that time. the key though is to figure out the pattern he's using by listening to where the others are that he's making contact with. Example; maybe he makes 4 contacts per frequency then immediately moves up 1 kHz for the next 4.
