Hi all

I had fun, worked 3 stations in total:

Mike G4RMV
Zdenek OK2PUX (QCX)
Zdenek OK2BQN (QCX)

Not bad! See you at 0300Z

Regrettably had to accompany the XYL to a tile showroom where I have suffered a near-fatal attack of acute BOREDOM, which I tenaciously survived by a narrow margin. On top of that there were (and indeed, still are) severe thunderstorms in the area so even had I been in the lab, no doubt I would have ripped the antenna out of the QCX. 

Anyway... with any luck, by the 1900Z session (10pm local) the lab techs will be all fast asleep tucked up in bed, the XYL installed in front of the TV with a nice mug of hot tea prepared by her tea-boy (a.k.a. yours truly), and assuming the thunderstorms have vacated the area, and assuming electrical power is not having one of its frequent outages (or at least, has not been unavailable for long enough to deplete my miniscule UPS battery), and assuming that no proximous lightening strikes have destroyed any BS170s or such, then I shall look forward to participation on 40m in the 1900Z and 0300Z sessions.

Re: Anybody have some good hints to tame frequency drift on 6M.

HF
 

Hi Dave

Another matter to consider:  When the U3S starts transmitting, its finals warm up and the heat dissipation of other components in the circuit changes, too.  The TCXO will adjust itself to hold its frequency as well as it can.  I'm amazed at how well that is, but it's still not perfect.  To slow down the TCXO's temperature changes, I mounted it on 3 very thin wire strands, about 2 cm above the board.  Then I stuck a piece of foam under the TCXO.  Those wires take a little longer than PCB foils would take to conduct other components' heat to the TCXO.  But they become inadvertent antennas.  My U3S is now inside a metal enclosure which somewhat contains that radiation. 

Cheers

Re: QCX40 Transmit not working questions #qcx40

Ronald Taylor
 

John, that pin 9 is the "signal out” from the microprocessor and is only used to turn on the tst signal when you are doing the alignment procedure. It shouldnt have any effect on the transmit signal path during normal operation. Changing ICs is the last thing that should be done after all other processes are exhausted. I would recommend that you continue with the test procedure and see if anything else comes up out of range. Good luck … Ron

My QCX40 has the following issues:
* does not transmit
* receive seems okay. Maybe reduced sensitivity. 
* loud static when I move the BNC connectors that connect the antenna. Swapped out connectors no change. Checked bnc jack solder joints

So I followed the Transmit Troubleshooting and found issues with IC3:

In receive mode IC3 pin 9 = 1.08v.  Rest of pins measured as they should. 

In smith mode IC3 pin 3,4, and 10 measured 0v. Pin 9 was 1v. 

So does that indicate I should replace IC3?  What else should I check or what do I do next?

Re: Updated Firmware to newest version

Yesterday, I tried to program a blank 328 part with the .hex and .eep files Hans sent me using avrdudess and a Sparkfun AVR isp programmer.  The hardware/software combination works as-advertised for programming in the .hex file and flags, but fails on the .eep, returning a verification error indicating nothing was written (0x00 data read).  I did set the -F directive.  Any thoughts?

My apologizes if this is somewhere on the board that I haven't been able to find yet!

Hello Hans,
wiring seems ok. TXD , RXD , the resistors and the 1N4148 as shown in the drawing. My first attempt eas to test the general function and Connection to my logbook and cw skimmer , via LPB2 ( Software that shares the serial port ) . This first test was ok.  Second i tested my programs without LPB2 , standallone. 
CW Skimmer and my UCXLOG want not to connect to QCX. Checked Port , Baud etc. everything was ok, so i did not care and went back to LPB2.
Than i wanted to go on air and saw that something went wrong with the keyer, i changed to straight ( than the Menue Crash happen)  but the setting was ok despite the menue is showing nothing ore strange characters.  Playing with the straight key same problem as with iambic …. seems the scan of the keyport ist deleyed thus leading to inaccurate  (morse) characters...
Next tests to be done:
- Disconnecting all programs from the serial port 
- Disconnecting QCX from serial / usb converter --- means --- disconnecting QCX from serial port at all and and test menue and keyer without serial traffic.

I will report more this evening…..

(P.S: All programs in use work since a long time with my TS-480 --- so nothing "new" was introduced  in my Environment, except the usb / serial connector. One of the next tests will be to replace the usb/serial converter with a serialTTL to serial converter to see what is going to happen ….

Hello Denis

Are you sure the wiring is correct? LCD connections to serial port? Correct fuse values?

I've made quite a few more code changes since Thursday (compression algorithm, putting WSPR back in, and the real time clock display). But I didn't operate with the new version yet (too scared of contests hi hi) but did a few CQs in practice mode and it seemed fine... but I will attempt some more in the QSO Party this evening.

I had a quick go yesterday hoping I could do some testing during CQWW.  My programmer arrived and flashing the chip to 1.03z actually went without incident much to my surprise.  Thanks to all who commented on that thread I knew what to do, what to look for and what to avoid.  I attached the CAT leads to the QCX as per Han's diagram and set my N1MM logger to TS480 with a baud rate of 9600 to match logger, serial port emulator and radio.  I think bits are working.  Turning the vfo knob on the qcx causes the green led on the serial port to flash in time with the detents.  N1MM seems to recognise that it has a TS480 connected but can't seem to control it or read from it.  I always computer key using a winkey emulator so the radio sees it as a straight key.  I know that works fine.  Its very possible that I have a local hardware or driver issue and I'm trying to get to the bottom of it.  More to come.

Hello Bernie 

Bear in mind I'm still new to CAT. So maybe I'm confused due to that. But please explain. Some of those commands, such as moving VFO or RIT up or down steps, must necessarily be SET commands. But you mentioned you implemented read-only CAT. What am I missing?

Re: More paddles and keys ...

Mike Easterbrook
 

Hi paddle key specialists/builders.
Hope this is not too far off-topic but hoping one of you can help me with a repair of my old G4ZLP key so that I can start using my newly completed QCX 20.
I dismantled the key as it was in need of a good clean after more than a decade of neglect.  In doing this I managed to mangle one of the two tension springs - could not find anything remotely similar in my "bits" boxes.  It is basically a 4mm OD tension spring with an ID which accepts a 3mm (M3 screw).  The OD is not that critical but the ability to accept the M3 screw is.  Only need a 1cm length or greater that I can cut.  On-line search has found some apparently similar items but not happy to spend out more than the key's worth after minimum order size and shipment from US or EU is added.

Grateful if you could take a look in your bits boxes or point me to a more economic source.

Thanks
Mike 9M2LXM/9V1LX
