Re: VHF Radio
If buying a radio right now be aware that after March 25 2011 VHF Marine radios must be DSC Class D or above to be Imported, Sold, or Installed in the USA. So a Lot of dealers are trying to get rid of their DSC Class SC101 before that date.
I like ICOM and Standard but most radios are very good today. I suspect there will be some new model coming out soon to replace the models that can no longer be sold.
Take your time and get the features you want and need. Larger Speakers are easier to here over engine noise and wind. Larger displays easier to see the channel numbers and GPS position displays. Some units like the Icom 504 will tell you what each channel is used for. Almost all units today are at least dual watch and scan so you can monitor channel 16 as required and scan the fishing channel or Vessel Traffic Service.
If you really want to research before you buy then search on line and read the reviews and before you buy down load the operator manual. Some are much easier to to program and use.
