MoBOB, you kind of stumped me. It would not be the normal VHF bands used for marine traffic. Most VHFs on board commercial vessels are for line of sight communications. For example, using "Channel 13" you would talk with another vessel and come to some arrangement on how to meet and pass. These certainly do not have enough range to cover the 700 miles wildman800 would need to cover between work and home.
However, I do recall the SSB at the dispatchers' desk that was used to hold conversations with boats that were not anywhere within 100 miles of the office. You could get much better than line of sight from a regular VHF, but not the kind fo distance the SSB unit got. I am pretty sure I recall a conversation on it with a boat at least 1,000 miles away.
I looked for some info on the web, but did not see much that describe dhte differences. BoatUS has a page on VHFs (
http://www.boatus.com/onlinecourse/documents/COMMUNICATION.html) that mentions SSB. It states, with regard to VHFs:
"They come equipped with a choice of transmitter power: one (1) watt for very close communication (approximately one mile or less) or twenty five (25) watts for extended communication (up to approximately twenty five miles). All of this is done usually with the push of a button.
If you need to communicate over a greater distance consider installing a Single Side Band (SSB) radio - which has the capability to transmit over hundreds of miles. If you are not sure whether you might have the need for Single Side Band radio please feel free to contact us at your local BOAT/U.S. Marine Center and we can discuss the pros and cons."
So, I'm not sure what bands. Honestly, I saw it used a few times and uonly myself ever used it for a few seconds. I just know they exist. From what I saw in my internet search, they have 150 watt units for $1,000-$2,500, but I know the price used is a mere fraction of the price new.
