Yep, glad she dodged that bullet. I can't imagine how scary that must have been. I carry aspirin and nitroglycerin everywhere I go, just in case...

Thanks for the kind words Guys.

Wife has been home since Friday evening, and all is looking good so far. She's extremely well considering she almost died on the sofa/setee last Tuesday. Good job my local hospitals are some of the best in the UK for cardiac care, and I was able to spot what was occurring and act swiftly. Thank feck for my previous medic training. I realise now that I need to include some dissolvable aspirin in my IFAK supplies. 

The second batch was a success and the third batch of 8 (remember I have 40 cells (5 batches of 8) to process) is now nearing completion.

Its a slow job but so far has been yielding good results. The chargers are fairly simple to operate now I have the hang of it. I may record some video of the next batch being processed now I have a bit more time on my hands.

Thatís true, they do, because there is no electronic keyer involved. Sides swipers and cuties are also aloud. Pretty much anything that doesnít involve electronics. But straight keys still rule there and whatever type of manual key is being used, speeds are still relatively slow.

A great forum to set up skeds with people is the Straight Key Century Club (SKCC). They have a webpage just for setting up skeds with other people who use a straight key. It's a great way to get your feet wet with CW. Since everyone is using a manual key, the speeds are slow and the people patient.

I looked into that a while ago. Think I read somewhere that they consider semiautomatic bugs (e.g. the original Vibroplex) to be manual keys. I am not able to relocate that rule now; is this correct?

To paraphrase Kopernicus:  'And yet, QRP works.'

I did study the history of astronomy, for a long period. Kopernicus was my great hero then and now. However, that famous quote is attributed to another great astronomer, a century or so later:

Congrats on your ft817 purchase. I've never owned one but I don't think you can go wrong with one.

I have done some QRP SSB though, and I can say, it's not for the impatient. Contacts are rewarding and as Gil says, with practice you will make more and more. There are tricks to QRP, like calling a guy right after he finishes a QSO with someone else (tail ending), checking into nets, break into a rag chew where the people sound friendly and inviting, answering other's CQ's rather than sending one yourself.

A good way to test the abilities of your station is to make contacts with people you know are listening for you. Set up a sked with someone on this forum or any other of the numerous web forums. Send an email to someone in your local ham club asking if he's free for a sked. Even during this time of low sunspots, 80 meters NVIS works wonders, even at QRP, for local and regional contacts. Or activate a SOTA summit and spot yourself. You will be the center of a pileup in no time and most of your chasers will give you realistic signal reports.

A great forum to set up skeds with people is the Straight Key Century Club (SKCC). They have a webpage just for setting up skeds with other people who use a straight key. It's a great way to get your feet wet with CW. Since everyone is using a manual key, the speeds are slow and the people patient. Plus, for QRP, CW has several db advantage over SSB and your experience making CW QRP contacts will be more akin to making SSB contacts at 100 watts.

You've got a great setup. Stick to it and don't get discouraged. If you're not careful it may become an addiction.

Gil, Thanks so much for pointing out what should have been obvious. I feel like a fool for not thinking of it myself. It works like a charm. If I run the coax inside the bead without any loops I have to have the bead up by the base of the antenna. If I loop it through just once (like in the photo) it gives me perfect SWR on the HB-1B meter no matter where it is on along the coax. It even shows low SWR over a much wider range of the band.
