On 24891.7 kHz, the FT-450D is receiving a sweet note from the transmitter of the stock QCX-17
In his QCX manual, sections 7.6 & 7.7, Hans includes some very interesting info about transmitter & receiver sections' filtering, mostly featuring the xmtr lpf and the rcvr bpf circuits.
Currently, using the stock QCX-17, the WM-2 reports something on the order of 300 williwatts into the Bird 10A-MFB-30 attenuator/dummy load.
So, now, I'm wondering aloud:
"Do I wait for the QSX to arrive or do I dive into QCX's lpf and T1 etc whilst waiting?"

Re: QLG1 GPS Receiver for use with the Icom IC-7100 or ID-880H

did you connect the 3rd pin or 4th pin of the 6 pin header to the Tip of the 2.5mm? Kevin, I've no idea what you are doing, what is this IC9700? But COM ports connect RXD to TXD and TXD to RXD. Crossover. 73 Alan G4ZFQ

This post may help me with my problem. I have a IC-9700 and tried to hook up the QLG1 to it, and just like the original poster's description, the Icom did not see it. I will check out one of the MAX3232 and see if that fixes my probelm.
Just one question:
When the advanced radio manual? says to connect the 2.5mm cable like this:
Tip = TxD
Ring = RxD
Sleeve = GND
Is the TxD as referenced by the QLG1 ? in other words, did you connect the 3rd pin or 4th pin of the 6 pin header to the Tip of the 2.5mm?
thanks,
Kevin?

Has anyone ever connected QLG1 to an Arduino Uno?
Looking for a sketch to verify the output of the QLG1 is working correctly.
thanks,

The Teensy range of microcontroller boards is popular because it has an audio library that makes use of its core's DSP instructions. The developer has created a graphical tool to make this easy.
Rich Heslip VE3MKC and Charlie Morris ZL2CTM have both done some work with this and documented their efforts but there are other things that can be done including experimenting with various filters.

My QCX 40 m has been tested and furthest it has worked is into Madrid so far. Last night I had my first QRP to QRP contact with my 3 watts and the other guy running 5 watts, that was a 12 minute QSO.
Just found reasonable band conditions on 20m and my QCX 20m rig has had its very first contact with Bulgaria at over 1,500 miles.... not bad for it's first QSO.
I am very impressed with these kits, they make up into a brilliant QRP rig.
Hans......? you are a genius.

You think that *you guys* have a shipping story !
?
I ordered one each QCX-80 & QCX-17 back around the autumn of 2017.
At that time, they were kitted in Japan.
As I recall, delivery time was about three weeks.
?
I dragged my feet for several weeks after delivery...
After a heart attack and a stroke, followed by triple bypass surgery, the 'Small Packet' from Japan sat, unopened, on a workbench for a year and a half...
But, don't worry, I'm back in great shape now !
?
eh? What's that, Dear? Oh, please excuse me for a few moments, fellas...
?
The wife had me join her to finishing watching 'Just like Heaven', starring Reese Witherspoon and Mark Ruffalo...nice flick !
Ok, I'm back.
?
Martha asked me in '17 if I'd let her keep those Japanese stamps..."Of course", I replied.
?
So, anyway, fast forward to Spring 2017.
I met my new ham friend, Bill, AF4YF from Patrick County, Virginia on 80 CW a few months ago.
Soon thereafter, Bill & I had lunch together and I invited him to our home to see my stuff...
At some point, I said to Bill "Have I got a deal for you !".
So, I told Bill that the QCX-80 kit was his, provided that he would build the QCX-17 for me.
He agreed!
?
Oh, yeah, a couple of months ago, I ordered an assembled QCX-80 from Hans' outfit in Turkey.
That order also took a couple of weeks to arrive...WELL worth the wait!
Once again, Martha gets the stamps, this time, from Turkey.
?
And, the rest, as they say, is history !

Re: U3S - xmit frequency is 200 Hz higher than indicated on display
Hi John
? This is Klaus, DL2QB (also WN2Z). I am not sure if I fully understand your question. Just connecting the U3S with a GPS and then doing nothing more won't guarantee that the U3S is working on the proper frequency indicated by the display. Unlike the procedure with e.g. the QCX QRP tfansceiver where you onxe set the proper osciallting frequncy in the beginning and leave the QCX alone more or less, on the U3S you must set up the correcting frequncy calibration after every cycle of WSPR transmissions- So you should specify how often and too what degree the U3S is commanded to compare the frequency of your master oscillator (not the one that controls the clock for the processor) with the standard it has just received?? (pps pulses) from the GPS unit. You can specify in what steps and how often your oscillator has to be compared with the GPS standard and after that has been done, the U3S will correct the U3S oscillating frequency accordingly. After such a correcting cycle you will see a short message on the display that says -003 or +015 or 000 which will tell you how many Hertz (Hz) the frequency has been corrected. If you have your U3S close to a window pane you can easily see the drift of the xtal oscialltor due to the change in environmental temperature. If you don't set up this calibration cycle like described in the U3S manual, the xtal oscillator may drift so far that the final transmitting frequency is off -and in worst case- outside the WSPR band. My aplogies if I have not always found the proper wording, English ist not my mother language and may be I also did not fully understand your problem.

U3S - xmit frequency is 200 Hz higher than indicated on display
First off, my apologies if this has been answered/discussed/in the manual. Some kind soul emailed me saying I was transmitting 100Hz outside of the WSPR frequency range on 30M, I always thought I didn't get very many reports due to my antenna, etc. I dropped my xmit frequency by 100Hz which put me right at the top of the WSPR range and started getting a bunch of reports. I dropped the frequency another 100 Hz (200 Hz in total) which put me right in the middle of 30M WSPR. Now I'm getting >= 20 spots every hour.
This U3S has a GPS that is successfully talking to the U3S and I was under the impression that with the attached GPS, there was no need to fiddle with the oscillator frequency. I could lower the oscillator frequency by 200 Hz but then what's the point of having the attached GPS? What don't I understand here? Again - sorry if this is a dumb question.

On my orders, once they left Turkey there was a period of tracking silence until the reached? customs.

Hi,
I have a couple of kits coming here in the Great Lakes region USA. I see
the kits left Turkey a while back and nothing beyond that. I just have
to wait. Not everything carries "instant gratification". It took me 72
years to order the kits. A few more days one way or the other will not
matter at all.

YAY ! Finally had my first 17m CW Q using the totally stock QCX-17 !
Decided to tune around the 17m band to see what I might fine.
There was XE2V calling CQ on 18082 kHz.
Had a quick Q with om Mode after which he worked a bunch of others.
QCX-17 finals nice & cool at 2.5 watts out to the GADS! antenna.
OK, back to 15 meters...

Re: A somewhat more complete description of my (ab)use of the QCX-17 and QCX-80 transceivers
Probably more than you ever wanted to know about an overworked QCX-17...
With appropriate external filter ( except, none for 17m )
?
OHR WM-2 QRP Wattmeter Bird model 10-A-MFB-30 attenuator as a dummy load
?
3.9 Band = as per band of operation
?

?

?
5332 kHz? ? 1 watt ? ? ? ?250 milliwatts
?
7001.7 kHz? 1 watt ? ? ? ?500 milliwatts
?
10101.7 kHz 4 watts 3 watts
?

?
18069.7 kHz 2.5 watts? 2.5 watts
?
21001.7 kHz 1.5 watts 1.5 watts
Yes, there's that thing about class E amps.
But, have a look at my RBN spots for the current 'RBN week' - all spots of the QCX-17 with appropriate external output filter.
Have also made a few actual QSOs using the stock QCX-17 on 30 & 20m. None yet on 17 due to poor condx.
QCX-17 works well on 15m too but spots are hard to come by on 15 due, again to poor condx.
When operating on any band, I keep a couple of fingertips on the finals to get a 'sense' of how they're doing.
I've been too lazy so far to put a 'scope on the drains of Q1, Q2, Q3 but, I'm pretty sure I'd see them coming out of saturation :0)
?
The QCX-80, with its built-in 80m lpf isn't nearly as frequency-agile as the -17 is for obvious reasons...unless we decide to rearrange things a bit.
?
Oh yeah, my -17 is now a 7-band rig ! Only manages about 500 milliwatts out on 80 but, sometimes, that's enough.
80, 60, 40, 30, 20, 17, 15m...plus CHU 3330, 7850, 14670, and WWV / WWVH 5000, 10000, 15000...haven't yet heard WWV on 20000 kHz...matter of time and condx.
Oodles & boodles of broadcast stations too.
Any questions ?
