Hi all. I am experiencing a weird situation, I apologize ahead of time as I am a newbie to the 817. When I plug in an external battery the radio is not seeing it. I have a car power adaptor which it

The only good filter is a cw one by Yaesu The Yaesu SSB filter is a bit better. qRP ARCI has an article on them and the graph showed some tighter skirts but I found it wasn't worth $279 Canadian for

I posted *two* (2) vendors. Page down and look for the vendor in *UK*. The *Collins 500hz filter* (w/o board) is showing up overseas but you must *search and evaluate reliability of the vendor*. I

There are a couple of videos on YouTube of them, one in particular has some halfway decent audio and I was able to hear a little difference. The mutants just sounded a little richer in audio. But if

Yes, you will need to search and evaluate the vendors for the *"Collins filter w/o board."* I got mine on eBay from Japan for *$103* but he no longer has availability. I can't vouch for this UK dealer

? get the same, tried for over 3 weeks to join, even had a member post on there for me with no results, my e-mail and call sign are the same on groups.io as it is on qrz, no problem with other

I looked on Google Street View and (with apologies to the seller) that really

Why bother with a group that has such ridiculous sign-up rules? It's a fair indication of the mindset of the group admins ? I use my normal email address for groups.io but have a different one

You can buy a *genuine* Collins 500hz CW filter for about *$103* (from Japan, UK etc.) and *solder it yourself* *to an* *FT-817 compatible board* *made by Artur, SP6AB.* He sells them as a service to
