Grounding a SSB radio in a PSC 34

Anyone know how to tell if your Crealock has a grounding strap /wire for your SSB radio. If there is one where do you generally hook up to it. It seems like to run a counter poise around the hull would require punching a few holes in the bulkheads and putting on a dedicated ground plate would require punching holes in the hull. Thanks in advance .

Re: Grounding a SSB radio in a PSC 34

In our 1996 PSC34 the grounding foil appears in the cabinet just forward of the switch panel and next to the chart table. The cover to the cabinet removes with four screws. You can also get glimpses of it around the hull at places like the chain locker and the lazarette locker at the upper edge of the hull near the hull/deck joint.

If you do not have the factory installed ground plane, I highly recommend the KISS SSB/Ham ground plane system which uses tuned radials to establish the counterpoise. It installs in about 10 minutes and is an excellent substitute for the traditional copper foil ground which would be a nightmare to install post manufacture. Just Google KISS SSB.

Re: Grounding a SSB radio in a PSC 34

Start with a simple connection to the back of your tuner and the closest underwater thru-hull. Be sure the thru-hull is wire brushed clean and use a hose clamp to attach it. Work from there and add additional straps IF you need them. The Trawler Beach House: Is It Hard To Install A Single Side Band Radio? . Chuck

Thanks Dave and Chuck. Now that I know where to look I can give the hole saw a rest.

Re: Grounding a SSB radio in a PSC 34

Take a look at the older thread on this forum.

Ground plane on 34

Then look at this site.

Voyage of the Swan - A Pacific Seacraft 34 is Selected, Outfitted and Cruised Offshore

You'll find photos of a PSC 34 under construction, and you can see where the copper HF grounding straps run.

My boat has tabs to the ground at the foot of the quarter berth (antenna tuner) and in the electrical panel (transceiver).

You are right, Bill! I can't believe I didn't remember the pictures of the grounding straps on my own website. Getting old I guess. The pictures are on this page Build 3

Re: Grounding a SSB radio in a PSC 34

I hooked up the kiss counter poise and it says not to ground anything else to the ant coupler but I am getting "SWR too high". All ant continuity seems good. Do I need to ground more stuff.

Hose clamps don't make very good electrical connectors. Better to drill and tap a small hole in the foot of the thru-hull and use a machine bolt to connect with a ring terminal to a wire, or a hole punched through the end of foil folded into a triangle.

I regularly use a ground wire from the tuner ground stud to a ground connection with sea water in parallel with a KISS SSB. Results are good.

Re: Grounding a SSB radio in a PSC 34

I would pose the question to Carl at KISS. I am sure he would be happy to talk to you. He loves satisfied customers. I have known him to even visit boats with problems. He's in the Seattle area. His number and email are on his site. I don't think the KISS should require any other grounding. It is supposed to be a stand alone counterpoise. But, I'll leave that question to Carl.

Good luck with this.

Dave
