New To Radio / Re: QRP from a beginners view

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.

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.

Antennas / Re: Tuning the QRPGuys vertical tribander
« on: June 01, 2018, 08:43:13 PM »
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.

Good idea Gil!
I'll try that today.

Thanks Gil,
I put one wrap back on the inductor and tried it with both lengths of coax and my HB-1B. It seems that I  can operate the lower part of the CW portion when using 3 feet of coax 7.025-7.055 and I can operate the upper portion of the CW band with 9 feet of coax 7.055-7.100. Have other people experienced such a narrow Q on 40 meters? Perhaps I should buy QRPGuys QRP tuner and use that when using this antenna on 40 meters. I don't think I will use my MTR3B on 40 meters with this antenna without a tuner. I can't risk running a high SWR and not know it with that rig.

Antennas / Tuning the QRPGuys vertical tribander
« on: May 30, 2018, 10:34:44 PM »
Hey guys,
After reading many positive  comments here about the QRPGuys vertical tribander I decided to get one. It went together quickly and after a little adjustment got it working with very low SWR on 20 and 30 meters. I was using the built in SWR meter on my YouKits HB-1B. I know not the most accurate but it's what I have for QRP levels. Resonate on 40 meters was way to low so I wound up removing 2 wraps from the inductor and that got it up to where I need it. I was using just a short 3 foot coax jumper to connect to the rig. I decided to add 6 feet of coax to make sure it doesn't change anything. On 20 and 30 it didn't change much but on 40 it is now resonate way up in the voice part of the band with the extra length of coax attached. That is, unless I have my hand under the back of the rig, then the resonate freq comes back down to the CW part of the band. I'm thinking that I will probably operate this antenna with longer pieces of coax since I don't want to be tethered so close the the base of the antenna to operate. I can add a wrap or two back onto the toroid since I haven't yet snipped off the excess I had after taking two wraps off but that part of the wire is no longer insulated. What happens if uninsulated magnetic wire rests against the toroid? It will be fine as long as it doesn't come into contact with uninsulated wrap right next to it right?

Hi Phillip,
Welcome!
Suggesting a first rig for someone is hard to do. Of course you know the answer will be ďit dependsĒ. Iím partial to the Yaesu ft-450D as a starter rig to go in oneís shack. It is one of the best bangs for the buck with a good selection of filters and DSP. You can get one for under $500 like new. To get an icom with a similar set of features youíd have to spend almost twice that. It also has a surprisingly low current draw on receive for a 100 watt rig. Itís not that big and so can work well as a field day rig but itís a bit too big for real portable ops. I think a KX3 is about as big as I would go for a rig to go in a backpack. For ultra portable I like my MTR-3B. Itís CW only but boy is it small.

That sounds like an awesome nab. If youíre like me, youíll be nervous as hell on that first CW QSO but the rush will be well worth it.

Gil, youíre a very eloquent writer in English. Much better than I and English is my first language. No typos or grammar errors jumped out at me but I should let my wife read it if you want a better editorís eyes. Engaging intro and great points throughout.

Morse Code / Re: XXX
« on: May 21, 2018, 12:52:08 PM »
SOS recognition by skimmers would be very useful indeed. Itís a shame itís not implemented. With the miniaturization of HF rigs and subsiquent popularization of portable ops including popular activities like SOTA and POTA  more and more people are taking radios to isolated areas these days. This has also lead to a renewed interest in CW among hams. As good neighbors and safety conscious hams, we should see CW as a valuable and viable way for the growing number of portable operators to call for assistance. Skimmers should be made to recognize distress calls and perhaps some skilled and charismatic writer should campaign to revive the awareness of X X X. An article in QRZ magazine, on their webpage, on some popular CW, portable ops, and general ham radio podcasts. Spread the awareness and make X X X a useful tool in the portable operatorís toolbox.

No, this post is not about Vin Diesel or adult movies. Rather, itís a question concerning the old practice of sending X X X in CW for Pan Pan, which is a call for assistance in non-life threatening situations. As a pilot Iím familiar with Pan Pan and I was curious if there was a way to call it in CW. So I googled it and discovered it was three xís sent as distinct letters. Iíve been messing around in CW for a few years now and never have come across this yet so it is not common knowledge like SOS is. I got to thinking about it as I was driving through a really isolated stretch of mountain roads last week, miles from cell service and thought that a way of getting the attention of a ham on the CW bands would be real handy if I had a breakdown and needed to have a ham relay a message for me to my wife to let her know about it and send some help if needed. I know SOS would bust a pileup and get a dozen of willing helpers in seconds. Do you think sending X X X would have any affect at all or am I better off just calling CQ HELP or something like that?

Hey Gil,
Did you find a good enclosure for your 80 meter rig? I've almost got mine done but I don't want to put on the components that poke out until I settle on a case.

What's needed in a prepping digital mode is something that can be left unattended and save messages...
Here's my limited understanding of store and forward systems. If somebody wants to correct me or expound, I'm anxious to learn.
Every store and forward needs a running radio connected to a server. Most of them these days use servers on the internet so when the internet goes down so does the server. Some have local servers, like many Packet radio repeaters designed to work without the grid or internet. Winlink and APRS can use local servers as well but to my knowledge, most use internet servers. In any case a grid down situation is going to require a powered radio with a local server that can run without grid power. Having someone else do that for you can be convenient in that you don't have to leave your computer and radio running all the time. But then the success of you getting the message depends on someone else's setup working.
For keeping messages locally at my own QTH, using my own radio and computer, I would currently go with FSQ. It's designed for this. Messages can be sent directly to you and give you an alert when someone tries to contact you. The messages are stored so long as the software is running.

Merry Christmas guys!

Good on you Ray. Awesome Christmas present!

On the top of my Christmas presents this year was: solder smoke filter fan, hot air gun, and a flat earth T-shirt; because everyone knows that if the earth were actually round HF signals wouldn't get past my front stoop ;)

Looking back at it now, it sounds like all I got this year was a lot of hot air.
