Marine SSB Stuff (how-to better use / properly-install SSB, & troubleshoot RFI, etc.)

Mathias,
Contrary to your thoughts, this is not the thread for a VHF radio / VHF radio range / VHF antenna / VHF coax cable questions.

There are threads on these subjects, or you could simply start your own thread....it takes no more clicks of the mouse, doesn't take any more time, and doesn't cost any more money (it's still free!). LOL


If you wish to look at VHF (and AIS) radio range and radio propagation, as well as details on cable loss (and why it usually will make no, to little, difference), have a look at these threads that deals directly with that.

Please read those threads, and you'll have a much better understanding of the systems and issues....(and, why being "sold" low-loss cabling is just a way to taking more of your money!)
And, then either start your own specific thread here, or ask questions in those threads that are on-point.


Until then, to be clear you haven't provided enough info to completely answer your question, but the quick, short answer is:
It's likely your friend either has some receive issues (possibly RFI), and/or you both have antenna pattern issues, as you mentioned you have an AIS antenna sitting next to your VHF antenna? (this is very bad engineering, and is discussed in detail in other threads, have a look....)

Again, this is not the thread for this discussion....HF radio is not VHF radio!
[But, I personally have a great deal of VHF comms experience....both engineering and real-world operations....it's just that this is not the place for that discussion.]

Fair winds.

Hello to all,
I've been away from here for a while.
Taking care of family health matters.

I hope to add some updates here in the coming month or two.
(I may even publish some new videos?)

Fair winds to all.

Hello again,
I just saw a message from someone here that reminded me that most of the old (10 yr old) links from the SSCA, etc. are no longer good hyperlinks.
{sorry about that ---- the SSCA changed all their polices and their discussion boards / website went to a paid members only site.... ....and the USCG re-did the websites, as did Australia and NZ, etc....and bruneibay site is no longer...}

BUT...

ALL the Cruiser's Forum links and Youtube links are still good (those are the ones I use and have some control of)!

And, if you're looking for the updates, you can see that there is a wicked-amount of info and updates right here in this very thread (beyond the first posting from 10 years ago)!

But, if you're looking for some quick links (rather than reading through the helpful details here in this quite extensive thread) ---- that might get you somewhere quick ---- have a look see here:

Now, all of the links I'm posting here tonight, in this posting, are here in this thread/stickie....along with a lot more (including info on the M-802, RFI, radiowave propagation, etc.)
But, since some might only look at the first post of a thread/stickie, I thought I'd at least try to post some links here that ARE active and useable!


I hope this helps?

Fair winds!
