no ……. not the roller coaster at Coney Island – but a new kit from the Four States QRP Group, designed by Dave Cripes NM0S.

“The Four State QRP Group is pleased to announce the availability of the Cyclone 40 Transceiver.

This innovative and simple transceiver by NMØS is an enhanced version of Dave’s QRP ARCI’s 72 Part Challenge Design Contest entry in 2010. This is a complete kit, including the enclosure. The price is a buck a part plus shipping, $104 total, for domestic sales. Purchasing info and more details are on the kit’s home page here  http://www.4sqrp.com/cyclone.php  Here are some of the design features:

.  All through hole parts and easy assembly. NO SMD parts
.  Less than 100 components
.  Superhet receiver with very good sensitivity and selectivity
.  “Perfect” QSK very high speed and absolutely seamless operation.
.  VFO tunes the entire 125 kHZ CW segment of the 40M band at a comfortable
tuning rate.
.  Transmitter output is nominally 4W.  Those built so far are running ~ 4.6W
.  Frequency readout is included so you know where you are at all times.
.  A very attractive PCB enclosure is included, asy to assemble, looks great.
.  All parts are included, jacks, knobs, enclosure, transformers, everything.
This is a complete kit, including a black enclosure with white silkscreened
labels.

We hope you enjoy this high performance transceiver.”

Looks like the Four States Group have come up with another winner. And at the rate these guys are coming out with kits, we’re going to have to change that famous advertising slogan to: “Like a good neighbor …. Four States is there!”

On a side note, this weekend turned out to be even busier than I had first imagined.  Other than my accomplishments of Friday evening, and an 8 minute QSO with Bob W3BBO on 40 Meters on Saturday afternoon to give a listen to his new HF2V antenna, I was not able to squeeze in any on air time at all.  And that QSO with Bob was a bit disappointing as QSB was so deep that it made our QSO more of an adventure than either of us would have liked. Of course, now that I do have time this Sunday evening, we have thunderstorms off the horizon. So for safety’s sake, instead of getting on the air, I have disconnected the antennas.  The past four days have seen 90F (32C) plus temperatures, for the first real bonafide heatwave of 2013.  According to the weather folks, the coming storms will break the heatwave, but will also have the potential for a lot of lightning, heavy downpours and gusty winds.

Ahh summer, you gotta love it!

QRP – When you care to send the very least!

I hope I don’t jinx it by writing this, but I think my weather station is now working. Everything is showing the values expected, including the rain which shows 0 mm as we haven’t had any. Trust the Cumbrian weather to not rain when you want it to.

It was actually Olga who got everything working. I had lost patience with it and was all for sending it back. Olga patiently went through the manual (which she found was poorly written) and double-checked everything. She even used my test meter to check the voltage of the newly installed batteries. She found that the rechargeable alkaline batteries supplied for the sensor/transmitter unit were only giving 1.3V each. So she took them out and replaced them with some new Energizer alkaline cells. And everything including the rain sensor started working!

The manual says “Insert 2xAA 1.5V rechargeable batteries into the battery compartment of the remote sensor and immediately afterwards 3xAA alkaline batteries in the base station.” It didn’t say anything about charging them first. If I had provided my own rechargeable batteries I would obviously have charged them first. But as they came shrinkwrapped in the box I assumed they were ready to use. False assumption! It was as simple as that!

I have just spent what seems like several hours trying to find out why my weather station data sent by Cumulus to the APRS network vanishes without trace. I have tried using the wxnow.txt method of generating APRS weather objects in APRSISCE and that does work, but unfortunately it messes with the MYCALL setting in my Kenwood TM-D710 converse mode TNC. So I thought that I would avoid the problem by getting Cumulus to send the data to APRS-IS directly.

The data packets were being sent but they never showed up on aprs.fi. I produced debug logs for both Cumulus and APRSISCE. These showed the packets being sent. So where did they disappear to?

To cut a long story short, Cumulus was sending the data packet with a path of TCPXX*. This is listed as “deprecated” in the APRS spec but it is actually blocked by the APRS-IS network software. The CWOP (Citizens Weather Observer Program) which I believe runs on an older version of the software, is not so picky so no-one had encountered the problem before. Can you believe that I must be the first person to try sending weather data to the APRS network using the Cumulus software?

Yesterday Olga and I set up a new weather station in the garden. It is a Nevada WH3080 SOLAR. It took a while for me to figure out how to put it together but I got there in the end with a bit of help from Olga (who took the radical step of reading the instructions!)

The sky is always blue in Cumbria!

We had a bit of trouble mounting the weather station in the garden. The manufacturer supplies two large hose clips (you can see them in the picture) which are not the ideal hardware for attaching a pole to another pole. But they did the job, if not very elegantly.

There were no problems receiving the weather station on the control panel sitting on the shack PC 10m away. This Nevada weather station transmits on 868MHz so no interference from or to 70cm amateur transmissions. No problems with the software either, not with EasyWeather nor with Cumulus which is what I will be using.

The software setup went so easily that I couldn’t see how it was working. When I plugged the display console into a USB port the PC went “ding dong” to acknowledge a new USB device had been connected but I couldn’t find the new device anywhere. I expected it would appear as a serial port in Device Manager but no new ports were added. I didn’t have to specify a COM port in either program either. How the console talks to the weather software is a mystery. I’m not planning to write my own software to process the weather data but I’m still curious as to how the software gets the data.

Using the example web pages provided with Cumulus I set up a Cockermouth Weather page very easily. Cumulus creates a wxnow.txt file which APRSIS32 uses to generate an APRS weather object. However I have just noticed that Cumulus can send updates to the APRS network directly. That would be a simpler way of doing it, but that way the weather object would not get transmitted to the local APRS network. I’ve since discovered an issue when using APRSIS32 to generate a weather object via a converse mode TNC, but hopefully Lynn KJ4ERJ the author of APRSIS32 will come up with a fix for it.

Summer arrived with a vengeance in Central New Jersey. Temperatures in the 80s (29C) with the higher humidity and stickiness that accompanies it. But it made for a great opportunity to head out to the park for some QRPing during lunch break. Besides the warmth, the skies were sunny and clear, with just a few white puffy clouds floating by.

Wanting to set up the fastest today in order to get the maximum operating time, I decided to go with the Buddistick on the magmount on top of the Jeep.  From the time I put the Jeep in park and turn off the ignition, I can be on the air in well under five minutes. Today was no exception.  The Buddistick is exceptionally easy to set up when using the top of the Jeep as a ground plane.  It goes together as magmount, two 11 inch arms, coil, and whip.  The whip gets extended all the way and the one coil setting works well for both 20 and 17 Meters.  The KX3’s autotuner gets a 1:1 match without breaking a sweat.

First up was Pertti OG2W in Finland on 17 Meters.  He was by far the loudest signal on the band and was a relatively easy catch even with 5 Watts.  From there, I went on over to 20 Meters and called CQ near the 14.060 MHz QRP watering hole.  To my delight, I was answered by fellow blogger, Greg N4KGL.  Greg was also using a KX3, but had his going to an Alex Loop.  Greg lives down in Panama City, Florida and started out at 559.  There was some QSB and at times the APF function on the KX3 was a big help.  Towards the end of our QSO, Greg was approaching 579. He was on lunch break also, and had to get going just as I did.

But as we all know, QRPing in the great outdoors can really be addicting, so I hopped on back over to 17 Meters for one last, quick listen.  Before I tore the station down and headed back to work, I was able snag Bob WP2XX down in the US Virgin Islands.

Three lunchtime QSOs – two DX contacts and a rag chew really made my day.  An added bonus was watching the RC Model airplane pilots doing their thing while I operated.  These guys are really good and I was treated to barrel rolls, Immelmans and vertical climbs as I worked the world with my radio.

I think tomorrow is supposed to have more of the same weather.

QRP – When you care to send the very least!

It rained ALL day, for the most part.  Not really heavy, but a good soaking Spring rain.  Just what I need to get the grass growing again after I mowed it Friday night!

I started the day with a nice rag chew with Joe W2KJ. I always get a kick out of working Joe.  He’s an outstanding QRPer; and it’s always a pleasure to chat with him. But I really get kick out of the W2KJ to W2LJ thing – our calls being one letter apart.

This afternoon, I worked VQ975FOC/MM. If he was in the Chagos Islands, where the call sign is from, that would have been quite the QSO at 9,366 miles away.  But as he was signing /MM, Jim could have been just about anywhere on the face of the earth. Shortly after working him, I got a tweet from Chris KQ2RP. He was intermittently trying to work the same station in between shack cleaning chores. When Chris heard the VQ9 come back to me, he redoubled his efforts and got him in his log, also.  You know what they say, “QRPers of a feather, flock together.”  Cool, Chris, I’m glad you worked him too.

I worked VP5/W5CW down in the Turks and Caicos on 20 Meters.  I have worked Dave several times over the years in the big DX contests. I guess he’s down in the islands getting ready for the CQ WPX Contest, which is next weekend.

I also got a new DXCC entity in the QRP log today.  By working CP4BT, I worked Bolivia with QRP for the first time.  I’ve worked that country several times over the years, but it was always QRO in the past.  This time it was with 5 Watts.  I am going to have to go through my log and see how many that brings me up to via QRP.  I think it might be somewhere close to 130 now.

I finished the day by giving out points in the monthly Run For The Bacon.  It seems pickings were sparse this month; and that might be no surprise. I am willing to wager that a lot of my fellow piggies were returning home from Dayton today and were just too tired to hunt for bacon!

QRP – When you care to send the very least!

A few days ago my Fox Delta WX1 Micro Weather Station stopped working. As it turned out, I just had to switch off the power and switch it on and it started working again . But while I was waiting for the rain to stop so I could go out and look at the device I began thinking about getting a better weather station – one that measures wind speed and direction and rainfall as well as temperature, humidity and pressure.

When you start to look at weather stations the choice is overwhelming. My first priority was that it should work with APRSISCE and generate the file wxnow.txt that it uses to update weather objects. That requirement led to the stipulation that it should be compatible with the free weather software Cumulus, which creates the required file. There is a list of weather stations that work with this software, which narrowed the choice down a little. After reading many reviews the best choice seemed to be the Davis Vantage Vue. Unfortunately this cost about four times more than I was willing to pay, so it was back to the drawing board.

The weather stations made by the Chinese firm Fine Offset and sold under the Watson brand name seemed to meet my criteria at a more reasonable price. However, browsing through the reviews on Eham.net and elsewhere there were quite a high proportion of dissatisfied users. Complaints about anemometers that stopped rotating, poor wireless reception and so on. With weather stations as with everything else, it seems, you get what you pay for.

Despite the reviews I am tempted to get one of the Watson W6861 solar weather stations. But before I did I thought I would take the opportunity to ask my readers for their experiences. Many of you must have home weather stations. So which ones are good, which are bad and which should be avoided at all costs? I await your comments with interest.
