Kenwood TS-570D Multi/Ch Encoder Sticking?

I’ve had a TS-570D for quite some time. Of course, I always say I go through more solder than log books, so it goes a long time between uses sometimes.

Lately, I’d noticed the Multi/Ch knob was “sticking” or behaving erratically. This makes it hard to do things like set filters and menu items. I don’t know if sticking is exactly the right word — the encoder would seem to rotate “the wrong way” and otherwise behave strangely.

I had about resigned myself to opening the case and cleaning out the encoder. A quick web search, however, indicated the encoder was sealed. However, on a Web forum I read of a strange fix. Apparently, if you rotate the knob quickly for a long period of time it will “fix” itself. The poster outlined attaching a cordless screwdriver to the shaft and using it to clear the fault.

Well I went low tech. I just rotated the knob manually as fast as I could probably 50 or 100 full rotations. And oddly enough that restored the encoder to like new behavior. I have no idea why.

But meanwhile, look for me on PSK-31!

Puxing PX-777+ Explained (in English)

The latest craze around here: the cheap imported handy talkies you can find on eBay. Local hams have bought Jingtong, Linton, Puxing, and a few more I can’t spell off hand.

I like the Puxing. It is FCC approved and has a lithium ion battery. It does cost a few dollars more than some of the cheaper radios, but it is still way under $100 shipped and works like a champ. The biggest flaw is the very poor manual.

So I took notes about what I know (and I what I could decypher out of the manual). You can find it in the

. A great radio at a great price!

If you know something I’ve missed, pass it along and I’ll add it to the article.

CQ PC – Ham Radio With a Computer

It is no secret that I have a lot of computers, and it isn’t much of a secret that I’m a ham radio operator. So it isn’t suprising that I use a computer for many of my operating chores.

There’s lots of choices for software, but I’ve been very impressed with DXLab. Just like Microsoft Office has a word processor, spread sheet, etc. DXLab has a log book, a rig control program, a DX spotter, and many other features. The user interface is not always the slickest, but the programs work together. That’s a huge feature.

Don’t let the name fool you. The programs are not just for DXing. You can load one of the programs, all of them, or anything in between. Here’s what’s available:

  • Commander – Controls many rigs via RS232 port
  • WinWarbler – Very powerful PSK31 and RTTY program
  • DXKeeper – Log book, interfaces with and LotW; tracks award status
  • DXView – Displays station locations graphically and optionally control a rotor
  • SpotCollector – Manages DX clusters via radio or Internet
  • PropView – Propagation forecasting and monitoring
  • PathFinder – Locates QSL information
  • Launcher – Launches sets of DXLab program

All of the programs are free and you can download stable or development versions. And they all work together. So if a station is spotted by SpotCollector, its position will show up in DXView. It is very easy to have Commander take your rig there, point your antenna (with DXView) and then put the other station in the log with just a few clicks.
