Ham Radio Onboard Flying Bear
Dick,I use a old Kenwood TS140 and an SGC Smart Tuner feeding an insulated backstay. I did add a ground plane inside the hull of my Catalina 38. The ground plane is made up of 3" wide copper ribbon. The ribbon runs from the grounding connection on the tuner (mounted in the aft lazerette), forward between the aluminum fuel tank and engine (copper ribbon connections to both the engine and metal fuel tank, then to a tapped hole in one of the keel bolts. As earlier posts mentioned, the ground is very important. The SGC Smart Tuner is fully microprocessor controlled and fully automatic. Key the mike and the tuner will sense the SWR and find a tuning solution within 500 msec. Once the tuner finds a solution, it stores the solution in memory so if you return to that frequency band again, tuning is almost instantaneous. The tuner memory can hold 500 solutions. The tuner is waterproof, and requires 12 Volts DC and has a remote indicator line to signal when the tuner is "tuned". Since the tuner uses SWR to tune the antenna, it will work with any radio. The downside is that the Smart Tuner costs about $350. I also have setup a TNC (terminal node controller) and using a laptop with the Airmail host program, am able to send e-mails from the boat via ham radio. Really handy at times!Fair Winds,Rodney KiddC-38 #297, Flying Bear, SF Bay
