QRPometer case….

Finished product

A few months ago I built and blogged about my  QRPometer build from the 4 state qrp club its a great kit. In the post there was only 2 con's that I could think of regarding the kit.
1.The TX and Antenna connections were RCA and not BNC, the kit now ships with the RCA to BNC      adapters.  
2. The meter did not come with a case and the rear of the meter had an exposed circuit board. I felt this left the meter vulnerable to damage.

My solution to problem number 2
first attempt....not good
We have in town a great electronics parts store it's been here for just a few years now but it's fantastic I don't have to travel for about 40 minutes to the next closest store. I ventured off to the store for a case, it was a plastic case I had in mind. The metal and or aluminum  cases I felt were just not as easy to work with for the needs I had. I brought the QRPometer with me to assure I got the right depth and width. I found a case that was deeper than I was wanting but it was all they had....so I purchased one.....that later turned out to be a mistake!!

With the chosen Hammond 1594E box at home using my machinist ruler I traced the cutout on the box that was needed to house the meter. The best tool to cut the case I felt was the Dremel hand held rotary tool that I had....so I thought!! With my pencil lines all in place the Dremel was used to make the hole, I found I was so consumed with the cutting line that I did not notice the spinning chuck that held the cutting blade was destroying my plastic box. As Murphy's law would have it this problem was only noticed after all the cutting was done. The top cover was a mess and since I am a VERY fussy person this just would not due. So it was off to the electronics store for another box and to rethink the opening for the QRPometer. It was not until I got home the idea came to me to use my coping saw. There is more control with the coping saw and a neater cut would be the end result. I also came to the conclusion that a smaller opening would be smarter as well, less cutting and less chance for a mistake. With the revised hole cut with
Meter in the new case
the coping saw the QRPometer with some tweaking of the hole fit just right. As always another thought came to mind........the meters power comes from a 9 volt battery that is sandwiched between the QRPometer circuit boards. In the future this battery is going to have to be changed. I am not going to want to take 20 minutes of dis-assembly and assembly to change a battery!!!! As you all know batteries go dead at the most inopportune times. It was off AGAIN to the electronics store for a 9 volt battery holder. I found the perfect flush mount holder and to instal it meant  to just extend some battery leads off the QRPometer board and cut but another hole in the plastic box. This was a very fast addition to the QRPometer box and the coping saw again made short work of adding an opening to the side of the plastic box.

No can do.

On Tuesday, when Mr. Liu from the NCC asked me for my opinion on matters regarding radio amateurs in Taiwan, I gave him my two wishes:

    1 – an English version of the exam, to get more foreigners licensed.
    2 – being able to choose your own call sign.

Both requests were torpedoed right away. First off, when the NCC would make an English version of the exam then they would also have make a Japanese version to accommodate them. And then an Indonesian version. And a …….. well, you get the drift.

Assigning call signs was a more sensitive matter. Even though the R.O.C. on Taiwan has been independent since 1949, it has not been recognised by many. Hence, over here we depend on the generosity of our next door big brother – the P.R.C. of China – to be able to use some prefixes from the ITU assigned block for China (Taiwan uses BM, BN, BO, BQ, BU, BV and BX, China the rest of the B-block). Amateur radio call signs are kept back for 20 years after expiry, so the resulting pool is small. So, unfortunately, once you get your call sign you are stuck with it, because the NCC doesn’t want to hand our new ones at your will. And even though changing areas would be a good reason, they still refuse. I am now living in area 3, but I still have to use my area 2 call because the NCC doesn’t want to assign a new BX3 call to me.

Luckily I am happy with my call. After all, ABT stands for “Any Bloody Thing” and that is how I enjoy the hobby: any bloody thing goes! Have a nice weekend.

Whisper it!

I was at home but too busy to play radio, so I did the WSPR thing on 10 MHz all day. Here is a screenshot of the local morning session.As you can see I am right in the middle between JA2GRC, DU1MGA and W8TOD in Beijing. W8TOD in Beijing??? There must be something wrong with his set up of WSPR! But there isn’t. On the QRZ.com page of Warren you can read the following:

I live in Beijing, China currently and am operating under the “less than one watt” and the “it’s legal if you don’t get caught” rules.

There you go! Stay under the radar, mingle in the crowd and you can get your radio fix, even if it is not allowed. The radio situation in Asia is messy, so turn it into your advantage.

Mind you, I wouldn’t do what Warren does and as I wrote yesterday, I am very careful in my actions, because I want to enjoy my hobby for a long time. So I do my best to play by the rules, but I will bend them if necessary.

Learning something new

You never know when you’re going to learn a new and better way of doing something. TJ W0EA posted this on the KX3 list, which led to (what I thought) was a fascinating discussion on how to coil and store antenna wire.

You’d think that winding up a wire antenna is a pretty mundane thing, eh?  But no, there is an art to it, so that when you’re out in the field, you’re not dealing with a tangled mess and cussing like a sailor on shore leave. I tried the method shown above and dang it! It works!

I love it when I learn a new way to do something better.

I am taking some needed vacation time from work on Friday and Monday.  Have to use what days are coming to me as I found out my department is being eliminated due to a contract change.  Originally, I was given to the end of August; but found out that I was extended until the end of October, in order to help train the guys from the new company that is taking over the contract.

But I digress. I still have a lot of yard work to do and hope to accomplish it over this prolonged weekend. But I am also hoping to perhaps get out to one of NJ’s state parks to do a park activation.  Maybe Hacklebarney State Park which is located between the villages of Chester and Long Valley in Morris County. If the weather’s nice on Sunday, perhaps the KX3 and the PAR can get a workout.

Show Notes #088

Introduction:

  • A sticky, stormy night in Texas, just right for podcasting and Russ’ attempt to take over the MintCast.

Announcements:

Topics:

  • Pimpin’ the network: If you have a podcast and want to reach LHS listeners, please visit Black Sparrow Media and contact us to become a member! The Waveguides Podcast did and so can you.
  • Who is your hero in amateur radio, living or dead? Let us know! Richard is gathering information for his super-secret project.
  • Storm watchin and workin on radios. While a storm raged in Texas, Richard received an email about an IC-735 that would not power on reliably. Richard’s trouble-shooting philosophy: start with the things that are cheap to replace.
  • Richard is hoping to pursue a high-speed multimedia (HSMM) and mesh radio project using DD-WRT or OpenWrt for use in emergency communications. Used routers, such as the Linksys WRT54GL, are ideal and can be found for little money.

Feedback:

  • Leif, KC8RWR, wrote to clarify a comment to episode 86, explaining that he’d like to try using an NE602 frequency converter to an RTLSDR radio to receive ham bands.
  • Brian, G3XGY, heard Russ on the Mintcast and is looking forward to listening to episodes of LHS! Welcome, Brian.
  • Leif, KC8RWR, offers a suggestion for Grant, who was having difficulty with the LHS live Linux CD handed out at Dayton. He thinks it may have been due to Linux not recognizing Grant’s video card. Thanks, Leif.
  • Harrison, VE2HKW, a sometime participant in MintCast, expresses his appreciation for episode 85, our interview with David Rowe and discussion of Codec2. Thanks, Harrison. Speaking of Codec2, Russ reports that David Rowe has won the 2012 ARRL Technical Innovation Award for his work on Codec2. Congratulations, David!
  • Harrison, VE2HKW, wrote to ask for help with his Icom IC-735 (as mentioned above).
  • Claudio of the LinuxBasement podcast thanks us for the mention in episode 87.

Remote control JT65 QSOs with my iPad and iPhone and the LogmeIn client

Recovering from a heavy cold and cough yesterday and because there was apparently nothing doing on 50MHz, I thought it was about time I got the HF JT65A gear going again, which I did and made some
enjoyable QSOs on 14MHz.

I’d wondered from time to time about making remote control QSOs. I use the Logmein client to control my PC if I’m out and about and just recently, I’d noticed that their iPad/iPhone client was free for the basic service. Since for datamodes, I didn’t need anything more than screen control – no need to ‘pipe’ audio, this should work just fine.

So last night, I sat on the sofa downstairs, with my iPad and tried to control the PC running JT65-HF. It seemed to work just fine. It felt odd calling someone without being in front of the radio and being able to tweak the power/alc settings and of course to be able to hear signals! However, I made the leap of faith and R2DX was my first ever remote control QSO. I followed on with AB1J and a German station.

I also have the Logmein client on my iPhone, so this lunchtime, I tried the same type of experiments across the Internet from the office. Although broadly successful, there was too much latency, and though I could see signals being decoded and press the appropriate buttons – the timing didn’t always work out correctly. Apologies to Harald DL8ZBA who must have wondered what was happening when I calleed him!

Nevertheless, this looks quite promising, particularly around the house and perhaps further afield when there is a good network connection.
