Colin, what did you do abt connecting the 4 control leads out to the SG230? The back of the 706 requires a proprietory Molex connector, available as far as I have found in batches of about 1000! It's possible to lash something up, of course, but I'd rather do better than that.

I used to build all my own gear. Passed my RAE in 1954.
Originally had the VHF only call sign of GM8BVD, Now it's GM3YND
Kenwood TS-130 SE. Ham band only 1.8 - 30 Mhz. It has a remote controller which gives 10Hz steps and the matching speaker. Nice set but I don't use it very much those days.
I should really sell it.
Other set is a Yaesu FT747 SX.
This is a general coverage set which can be quite usefull.
I wanted a 747 when they came out as as they were then so compact,but when in qso with someone useing one it kept drifting off frequency! dont see many for sale now.
Amature radio isent very good at the moment a few groups not so good propergation and not much chating and calls given unendingly it a trend! you just have to listen in to the uk MM net on 14303 they buy now give their call on every over!!! "who calling -g4frn its gx abc, from gy abc g4frn oh its gx abc from g4frn where are you now g4frn pewwww
There is also the new system that now VHF call can now operate on all bands. Thought not all national licencing bodies have implimented the rule, In fact the VHF call on all bands was aprroved two years ago just as the use up to 7150 from 1 jan this year radio broadcasters have primary use untill may and were restricted to 100w pep more than enough!
But with the Vhf call change saw HB9vhf calling G4 exz s and others only to be called a piret to be reported and just so much abuse it was and is a disgace to hear so many uninformed and rude people on the air
Things have changed!!Bst would be if everyone had to build their own rig or go qrp
I get angry especially with hypocrits and jelouse fools pretending to support sailing only to refuse and jam(illegally) transmisions from boats making atlantic crossings or comeing up the red sea once i had a row with some fool net contoller who did just that but then propergation changed and i lost the contact with some freinds on route to the carabeian- i lost contact fully with them as then we dident have email!!
just makes me mad the way things are in the Med ive taken my rig off compleate waist of time in the med i met someone who had taken his exams just to use SSB when in the med-within days he had given up declared it a waist of time and put his ts 140 up for sale!
Don't kill me but I have posted this reply and more questions as a reponse to other people who had returned helpful advise previously as well.
Hmm I checked the manual again and it recommends an AH-3.Hope the AH-4 which has replaced this is compatible. The AT-180 as some have replied was indeed the wrong choice since it expects a pre-matched whip antenna.
Now I have a generic question: The AH-3 comes with a wingnut to attach the antenna wire directly. Since the tuner is supposed to sit below deck and I do not like the idea to run the antenna "long wire" from there:: Is it detrimental if I run a coax section from the tuner up on deck and to the atual wire, or am I now messing things up again??

I think that you will find that the AH-4 will only tune down to the 160m band (or the 2 MHz marine band) if you have a very long antenna - how long I do not know, but much longer than 10 m, so would be worth checking if you wish to operate at those frequencies. It is rated as being able to tune from 3.5MHz upwards with a 7 m long antenna (longer antennas are ok, and as the frequency increases, then shorter ones too).
You cannot use coaxial cable from the terminal on the top of the tuner in any way that stops it being part of the antenna. If you ground the shield then the centre conductor and shield with the dielectric insulation in between will act as a capacitor and therefore as a short to ground for your signal - ie it will reduce the signal strength.
what are the options then? I gather if people on board touch the wire it wont be too pleasant?! Should I place the tuner as far aft as I can and then run a wire with high tension insulation to the wire antenna?
Yes that is right. Remember that as long as the boat is not metal the part of the antenna inside the boat radiates just as if it was outside so is not a problem from that point of view.
Some people advocate putting the tuner outside the boat to avoid the problem of having the high tension wire inside, as long as the tuner is claimed to be waterproof (many are). I, personally, do not think it is a good idea, especially on a boat - interestingly, SGC whose tuners are waterproof also recommend the same or if has to be outside then say to cover it with something to keep wet and sun off it (refreshingly honest /forums/images/graemlins/smile.gif).
Also, putting it outside will almost always increase the conductor length to the earthing plate or whatever is used, and that may also be a disadvantage.
