"QRL?" – please !!!!!

I did go out to the Jeep during lunch today, and no, the bands were NOT dead. But before I go there, I must digress.

I was involved in a 2X QRP QSO on 14.060 MHz with Tom, KC9RXI in WI. He was about a 449 to me; and I'm sure I was no better to him, but we were having a QSO.  I'm sure at times, that to people who may have been listening to the frequency, that it sounded like it was dead.

It wasn't.

All of a sudden, out of the blue, another QRPer started calling CQ/QRP on frequency!  The call will be omitted to prevent embarrassment (but it is forever burned into my brain).  Not so much as a single, solitary "QRL?"

Yes, I am sure that both Tom and I were weak, but we WERE in the middle of a QSO.  Coming on to a frequency, plopping yourself down and commencing to call CQ without asking is just - arrgh! And to top it off, the CQer was calling CQ DE WXXXX/QRP !!!!  I'm sorry, but QRPers, above all Amateur Radio ops, should know better. No excuse - period. If he had sent "QRL?" waited for a bit AND THEN had started calling CQ on top of us, I may still have been annoyed, but I would have thought to myself, "Well, he just didn't hear us."

Unfortunately, while Tom was trying to talk to me, I had to transmit "QRL. PSE QSY". He immediately QSYed (so he was able to hear me!), but at that point I had lost what Tom was trying to say. Shortly after that the QSB went off the Richter scale and the QSO came to a premature end. The "meat" that I could have copied was drowned out forever by needless QRM.

A bit after that debacle, I went to 12 Meters and tuned around for a bit. I heard 7QAA in Malawi quite loudly.  He was loud enough to work - even QRP. I don't think I broke the pile up, as again there was a lot of QSB. If I had more time (lunch hour was running out) I'm pretty darn certain I would have worked him. This time I had the patience - I ran out of minutes.

So , even with the G4 geomagnetic disturbance, Malawi was coming in the best I've heard them so far. Go figure.  Luckily, the station will be on the air until early April and I'm taking a vacation day on Friday. I just may make it into their logbook yet!

Review Baofeng FF-12P (UV-5X)

Probably because Baofeng is running out of letters (although I didn’t see the Baofeng UV-5Y or Z yet), there’s a new numbers game in order. The FF-12P is essentially a UV-5X and my sample came in…. silver.

Baofeng FF-12PThe radio houses the latest chip set and firmware. Pressing various keys confirm this: pressing ‘0’ for a bit more than a second shows the battery voltage, pressing PTT + Band generates 2100 Hz, PTT + A/B generates 1750 Hz, and PTT + VFO/MR generates 1450 Hz.

The display is of the inverse type, the antenna the short one we all learned to hate, “FF-12P” is printed on both the left and right side of the radio. Batteries / accessories aren’t compatible with the standard UV-5R. While I could find enough suppliers of the FF-12P and UV-5X, not a single one appears to sell spare batteries or any other accessory.

Charger / battery combination
I wasn’t able to charge the battery at first, because the battery and charger don’t match: the two indentations of the battery prevented it from being inserted in the charger. After scraping away enough plastic in the charger I got it to fit.

CHIRP
CHIRP recognized the radio as being a UV-5R and squelch thresholds could be modified without a problem.

Scanning
A clip on YouTube suggested that the UV-5X / FF12P scans faster. This proves to be true: the FF-12P outperforms all other Baofeng radios I own, including the GT-3 Mark II. Scan speed is about 5-6 channels/sec.

Transmitter

Frequency accuracy of the sample: +2 Hz on VHF, -11 Hz on UHF.

Power output VHF: (@ 145 MHz): 4.1 Watts (high), 1.7 Watts (low)
Power output UHF: (@ 435 MHz): 3.6 Watts (high), 1.8 Watts (low)

TX Audio: Bright and loud. Very nice.

Harmonics: the usual peaks on VHF and UHF. Still not very impressive.

UV-5X_FF-12P-VHF
UV-5X_FF-12P-UHF

Receiver

RX Audio: good.

Front-end: surprisingly good, just like the GT-3 Mark II. Nice.

Sensitivity: -127 dBm (VHF), -125 dBm (UHF). These are good numbers.

Conclusion
The FF-12P aka UV-5X is the typical Baofeng: value for money, but not without its flaws. Harmonic suppression is a mixed bag and the lack of accessories is a potential problem.

The fact that I had to modify the charger to make the battery fit is a dumb factory mistake. The short stock antenna just doesn’t want to die — put a few bucks aside to buy a better one.

The positive side of the radio is the good receiver, good TX audio and faster scan speed. And, if you care about such things, it comes in shiny SILVER!

My QRP signal is spotted in Europe!

I had some down time over the weekend and felt it was time to spin the K3's VFO and see what was out there. I started on 15m it really did not seem all that busy but I was hearing some German stations so the band was open. My Elecraft P3 is great as I was able to get a snapshot of the CW portion of 15m. This allows me to not spend time moving up and down the band blindly and maybe just missing some stations as they end their transmission. One could end up concluding the band is dead and move on when in fact they just missed a station or stations calling CQ and waiting for a reply.  I ended up calling CQ in and around the QRP watering hole at 21.060, in the past I have checked the Reverse Beacon Network (or RBN)  just to see how my QRP signal was doing. At this new QTH
P3 on 20m showing some signals
for some reason I have been only able to get spotted in Canada and the U.S. To my surprise when I checked RBN I had been spotted in Hungary, Switzerland and Germany. I was very shocked and it kept me on the band calling CQ. Unfortunately there was no answers I then moved onto 17m and was spotted in France but again no answers to my CQ! I then ventured down to my standby band of 20m and found F5GPE Pierre calling CQ. His signal was in around 559 and I gave him a call and he came back to me with a report of 539. I did send him an email thanking him for the contact, he did get back to me giving me more details about his setup.

Rockmite

As I’m moving towards CW as an operating mode I took the plunge and bought a Rockmite kit from Kanga. Lets just say its not working quite as I had anticipated. This time I was very careful to look at the various instructions. Lid everything out and then checked every component as I assembled it.

2015-02-28 18.51.57Next time I’ll throw these things together in the usual manner. I might have a bit more success. Power on and I get little in the way of audio, a gentle hiss but not much else. So troubleshooting has to begin. Fortunately there is quite a bit of help for this but to be honest I’m not holding out much hope as I did such a thorough job of checking the first time round. Must be a faulty (insert component here) ;-)

 

All good fun and not as if the world will end if I have to spend some time on it.

Spurious Emissions

AMSAT is offering a discounted satellite antenna package to members.  The package consists of two M2 antennas, one for 2m the other for 440, both circularly polarized.  Looks like a nice package at a decent price.  I’m going get this for the new bachelor pad QTH.  If you’re a satellite aficionado and not a member of AMSAT or another organization that launches birds, you should join and support one so we can keep satellites orbiting the globe.

Make has an article on how to turn your Raspberry Pi into a “pirate radio”.  This appears to be done all in software by outputting a high frequency bit stream on a GPIO pin.  The software will frequency modulate the carrier and it’s intended mainly to be a short range (i.e. unlicensed FCC Part 15 here in the US) FM broadcast transmitter you can play your tunes through while on the beach.  A more technical article, mentions it has 1 to 250 Mhz capability.  This might make a cool little exciter for QRP CW, with appropriate filtering to clean up what undoubtedly has a lot of odd order harmonics.

There’s this cool little Kickstarter project called Tsunami.  It’s an Arduino-based audio signal generator and analyzer.  Undoubtedly this could have some amateur radio applications, like generating and decoding digital modes.

One of the original Arduino founders who ran the main firm which manufactured Arduino boards is accused of going rogue and registering the Arduino trademark in Italy.  Arduino.cc is the original, core Arduino team and the Arduino LLC entity, and Arduino.org is Arduino SRL, the rogue manufacturing company.  Arduino SRL is no longer paying Arduino LLC royalty fees and Arduino LLC is now in a legal battle.  Any Arduino board that was purchased in the last year that was made in Italy did not have royalties go to the Arduino team which has been responsible for design, creativity, and energy behind the Arduino project.

Changing propagation

If proof were needed that we are now on the way down to the next minimum then take a look at the sunspot number graphs at http://www.solen.info/solar/ .

Although conditions are sliding, do not abandon the higher HF bands like 10m. There is (usually) quite a lot of good DX around still. In the last solar minimum I was still able to work well into southern South America on 10m with QRP SSB.  WSPR should be even more reliable when conditions are edgy.

I really do hope a strong core of WSPR operators stick with 10m as, in many ways, in the poorer times are when WSPR will be most valuable as a tool. I am hoping that when not on traditional modes like SSB or CW people will still WSPR so we can catch fleeting openings, which are probably far more common than people expect on 10m. Remember, the F2  or transequatorial propagation has only to go above 28.126MHz for 120 seconds and someone on WSPR may spot it!
