I own a variety of Yaesu ham radio transceivers and like them a lot. Except for that one little annoying feature that the FM rigs have: WIRES.

About once every two weeks, one of the local radio hams gets on the repeater with a DTMF beep at the start of every transmission. We’ve come to expect it now, so the first question to the ham is “are you by chance using a Yaesu radio?” They always say “yes” and then we talk them through the process of turning off the WIRES “feature.”

The WIRES function sends a DTMF signal at the start of every transmission for use with Yaesu’s version of internet repeater linking (which is not used much in the US).  The problem is that it is very easy to bump the wrong button on your radio and accidently get it into this mode. This means that this is mostly a nuisance feature in the US.

I recently came across a way to disable this feature on your Yaesu radio so that it won’t sent the DTMF tone even if you activate it by accident. Basically, you set the WIRES tone to be empty, so nothing is transmitted if you accidentally turn on WIRES. I did not come up with this clever hack…in fact, I am not sure who put this together. (If you do, let me know and I’ll give them credit.) Take a look at this pdf file and follow the instructions to de-WIRES your radio: Turn Off Wires

is one where I can rack up at least 4 QSOs during lunchtime. Today was such a day.

PJ6/W4VAB – Hugh in Saba, St Eustatius on 15 Meters. DX contact
IK2SND – Danny in Italy on 17 Meters. DX contact – Danny was 599+ in NJ.
K9WIS – Brian in Waterford, WI on 20 Meters. Short ragchew.
N4KGL – Greg in Panama City, FL on 20 Meters. Very short ragchew.

The QSO with Greg N4KGL intrigued me. Greg also does the lunchtime QRP portable ops thing, and we have hooked up several times.  He uses a KX3 to an Alex Loop.  He was a good 579 / 589 into New Jersey and the Alex Loop was doing a superb job getting his 5 Watts up here in good shape.  I may have to look into magnetic loops as a serious option for QRP portable ops.

On another note, sometimes, when you collect a lot of Ham paraphernalia over the years, you forget some of the stuff you already have. I am a case in point.  The other day, I was in correspondence with a fellow Ham who was looking for a very small, miniature straight key. I e-mailed him that I had one and was willing to part with it. In turn, I received an e-mail back, asking for a photo. I was searching the shack for it last night, for picture taking purposes, only to suddenly remember that I sold that very key along with my K1. It was part of the package that I had put together, back when I was trying to raise funds for my KX3.  I sheepishly informed the inquiring Amateur that I no longer had it (losing your memory is a terrible thing!), and was feeling bad for having given him inaccurate information. I was relieved as everything turned out all right.  He informed me that a friend of his had actually given him exactly what he was looking for, and that it met his needs very well.

But during my search for the straight key, I came across a Viz Key that I had purchased about 7 years or so ago. I had totally forgotten that I had it

And that was a fortuitous discovery, as for a while now, I have been trying to settle on a key to stick in with my KX3 in my portable QRP ops bag.  I was originally using an American Morse “Dirt Cheap Paddle”.  It was very good and had an excellent feel, but was just a bit too light for my hand. When I’m doing these lunchtime ops, I like to hold the paddle in my left hand and squeeze the levers with my right hand. Call me crazy, call me weird but that’s what works best for me. When I would try to find the “sweet spot” for the DCP in my hand, I seemed to always accidentally squeeze the paddle levers at the wrong time and would send out a string of inadvertent dits. Next I tried a TE-NE-KEY, but I just couldn’t get used to the feel of that at all. I ended up making more mistakes with it than I do when I am on a bug!  So I had resorted to using a White Rook MK-33 single lever paddle that I had. That was actually too light also, but I overlooked that, as I absolutely love single lever paddles.  

The Viz Key is an iambic paddle, but it’s a bit heftier than what I have been using, without being too hefty (it weighs in at 8 oz. or just 1/2 pound).  It’s just the right weight for me, whether it is in my hand or on whatever table I happen to be sitting at. It is stable without being cumbersome. If I was hiking for a long period of time, I’d probably switch back to the White Rook, but the small amount of weight savings is not a concern for me right now.  I used the Viz Key for my QSOs today, and it took a few minutes of getting used to again.  But very quickly, my sending became less error prone and I was able to make the QSOs that I did make without sending the Hams on the opposite end into a messy Morse Code frenzy.

I was enormously pleased to see a new post from my fellow blogger Roger, G3XBM Roger is recovering from a severe stroke and  facing difficulties I can only imagine. I’m sure I’m not the only one missing his posts about QRP projects nd accounts of his low power activities. Get well soon, Roger.

Fleets Cove Beach

Yesterday, on a day off from work, I had to head up to the Huntington Village post office to pick up a kit I ordered from China. Why my post office is a 15 minute drive (in traffic) from my home when there’s a beautiful, brand new post office, with a large self-service lobby half a mile from me is a story for another day. As-is the reason why my postal carrier is too lazy to actually leave me notices that I have a package, or ring the bell and ask for a signature. I retrieved the kit, and decided that since I was a few minutes from the North Shore, I would try for some 10 Meter mobile contacts from the beach. I headed to Fleets Cove Beach.

I plunked the mag mount to the old Buick, and plugged in my HTX-10. The band was busy, as it has been lately, but to the point where my 25 watts wasn’t getting through a lot of the pileups. One operator heard me and I logged that contact with Croatia. Not bad, but still disappointing, considering how busy it was. I was beginning to get discouraged, and thinking about calling it a day when I twirled the dial up to the AM portion of the band (29 MHz). Now, keep in mind that my HTX-10 only puts out about 7 Watts AM, and my antenna is tuned for 28.4. I had a nice QSO with M5AFD in Shropshire England. He was surprised at how well I was coming in, but there were a few deep fades. He also complimented me on the audio on the old mobile, and suggested that it would be close to optimal with a punchier mic. I may do just that.

England. AM. 7 Watts. WOW
