Sangean SSB receiver
This $280 Sanegan is probably the best under-$300 shortwave receiver. 75% of Amazon reviews are 4 or 5 stars. If you want the best reasonably-small, portable SSB receiver, this is it. Versus the Sony, this Sangean has more features, greater sensitivity, better & easier tuning, and arguably better sound. But at nearly $300, the Sangean is a hunk of change. For a little more money, you may be able to find an even better used Ham/SSB receiver, or, if you're really serious about receiving SSB/HF radio, splurge for a new ICOM R-75 ($620).
ICOM M802 Manual
One more in Captain Marti Brown's "Idi-Yachts" series of easy-to-understand books, this users manual is a must for anyone with an ICOM-802 radio. The 802 has many features and capabilities, and works very differently from ICOM's other radios. ICOM's 802 manual is lacking. If you want to get the most from your ICOM 802 radio, Capt Marti's book is a must-have!
Marine SSB Radio for "Idi-Yachts"
Captain Marti Brown's "red book" introduces the reader to SSB/HF/Ham radio in an engaging and easy-to-understand fashion. I only wish this book had been available when I was trying to learn about SSB radio. If you are comfortable operating your SSB/HF/Ham radio, then you've moved beyond this book - but if you're new to this, Captain Marti's explanations will speed you along the learning curve!
HF Radio Email for "Idi-Yachts"
Captain Marti Brown's "green book" introduces the reader to doing data/email over SSB/Ham radio in an engaging and easy-to-understand fashion. It includes a CD with audio samples of what you'll hear when trying to do email over HF radio. This is not a manual on how to use a specific HF email provider - rather, it is an overview of options for data/email over HF radio. Like Captain Marti's "red book", her "green book" is intended for beginners.
Modern Marine Weather
Once you've read my book on weather, "Coastal & Offshore Weather, the Essential Handbook", you'll be ready to move on to other weather texts - and David Burch's new book is an excellent 2nd step in your understanding of marine weather. The accompanying workbook (a separate item you can purchase when buying this book) is a unique reinforcing tool to ensure you fully understand David's topics.
Modern Marine Weather Workbook
What a great idea! Combine a good weather book (David Burch's "Modern Marine Weather"), with an interactive workbook. David reinforces concept learned in his weather book - a great learning tool, this workbook ensures you have a real understanding of marine weather.
