Radio and hatch.

Ed, how about some radio details? SSB or ham, make and model, ground plane, antenna type, tuner info, etc. Now that you have that big opening in the shower seat you could put a holding tank in there. :) Glad you posted that picture. I was about to cut the hole for a hatch. But I was going to put it in the front of the seat. I think I like yours better.

Where In Jacksonville?

Hi Ed, Where in Jacksonville do you keep your boat? We have a Hunter 34 in Oriental, and just love the cruising grounds in NC. Gary

37c

hi there: We have a h-37c in minnesott beach and we too love the crusing areas around the nc coast. The ssb radio is something that we want to look into eventually. Don't know much about it though. Have heard it is very expensive! Correct??

Ed, doesn't that hatch do a number on your butt?? Johnny, Figure on the cost of the radio and tuner (what, $1500 to $1700 or so?), insulaters (a couple hundred up) for the backstays, cable from radio to tuner ($100 or so), and the cable from the tuner to the backstay($20 or so). That leaves the ground plane, and that's a lot like a lot of other areas, as many ideas as people giving them. I glassed in about 16 sq ft of bronze screen under the cockpit, then talked to a guy in a harbor in Colombia my first try (from a Texas lake).

Yes..., and no.

A new SSB is very expensive for an H37C owner like you and me, but not for a Swan 55 owner. The recommendation you will hear most often is to get your Ham license(very easy) and buy a used Ham radio. You can find them on E-Bay or several shops like AES(www.aesham.com). For a good read on the subject see the Related Link(www.hfradio.com). Really like the Pamlico and would like to spend a season or two with Ladylove at Matthew's Point(www.matthewspoint.com). There was an H37C there the last time we visited.

MYST installations...LONG!!

Ok.. This is gonna be long!!!! The radio is an ICOM 706 MKII G..Tuner is a SGC 237, backstay is insulated in two places..The top approx 3 ft from the mast, bottom about 6 ft up..The tuner is mounted to the rudder bearing support in the lazaret, with the feed running out and up to the crimp above the bottom insulator, where it has a ss hose clamp attaching it the crimp..Feed line from the radio to the tuner is RG-8X, by Anchor..I used the center conductor out of some old RG-213 as the jumper from the tuner, wich is really part of the antenna, to the backstay...It runs along the pushput and then up the backstay, held with tiewraps..I can hear the knashing of teeth now..No I haven't noticed a bit of trouble routing it this way, tried it away from everything, and then up against, no difference noted in signal reports from the same stations.. Ground plane, is 3 inch copper foil, run fore/aft, with bronze screening installed in the "wetted" lockers/compartments..This is all connected to the copper foil, with foil where able, with leftover coaxial sheild from some RG-213 where not able to get the foil through..The screening is glued down with liquid nails..There is also a dyna plate, installed by MYST's privious owner (who also installed the insulated backstay), that is also tied into the RF grounding system... The rest of the installation is a KAM Plus TNC (terminal node controller) for email, and WX Fax, and running data keyboard to keyboard..I also have the MFJ TNC/Mike switch to keep me from going nuts trying to keep all the bit and pieces at th same ground potential.. TNC's plugged in to HF radios is one of the biggest cuase of lousy, distorted SSB signals going...Just about every distorted SSB signal I hear is instantly cleared up when we ask if the TNC is plugged in and they unplug it...The other reason is low batteries...Covers almost 100 % of them! The radio sells for around $800 bucks right now..Tuner on HRO's web site is $329, insulators are around 100 bucks or so, Amatuer Radio License is free... As far as insulating the backstay goes, you can get away with just using a single insulator near the mast, then you can feed teh chainplate from the tuner, which will feed the backstay, yes I know this makes the WHOLE backstay RF hot, but your not going to grab it while the transmitter is keys, trust me...I know several installatins that have a single insulator, with no one ever getting bit, etc... As far as the hatch being hard on the butt, who cares!!! It is easy to get to the available storage in that void now!!! I had thought about installing it on the from of the seat, and in some ways it would have been easier, except for getting things in and out..Just think how much fun it would be to be digging around in that locker on your hands and knees, with a little bit of bounce..Much nicer this way..Also, all the space is now useable..besides, how long ya gonna sit in there??? Water, water, water ya know.. *G* MYST is at Camp Lejune, on the New River.. 73 Ed bt
