Re: Clock range for QDX Lo ?
Hans
The QDX has worked well all this time. Both on the internal and all OK with the external 25 Mhz clock from the Bodnar GPS clock. I am just trying to find a combination to also clock my KIWI from this two-channel Bodnat. The cascading multipliers and dividers make it a challenge to find a double solution. All just fun. Thank you Hans for the good devices to operate. John |

Re: QMX on high bands?
¿ªÔÆÌåÓýHi all,I¡¯m currently working on getting the HB LPFs right and doing the first prototype QMX HB. It will be a little while though not too long as the QDX HB LPFs are fine, just need to get the values on T30-17s and T30-0s so no saturation.? When released perplexed will be able to run their own combos of LPFs as they choose. BPFs won¡¯t be that difficult to do either.? It¡¯s easy to run combos of 10/11/12 15/17 17/20 and even 20/17/15? In LPFs. BPFs are easy enough but remember only 4 switchable locations in the hardware, with a bit of compromise some multiple combos are possible.? We will do straight 20/17/15/12/11/10 first up.? 73 Ross 6 On 20 Jul 2023, at 01:08, Jeff <jeff.ve3cw@...> wrote:

Re: #QMX firmware 1_00_004
#qmx
The receive offset seems to have been caused by the sideband option in the SYSTEM CONFIGURATION terminal entry. I had changed it to LSB to try to fix a problem and had changed it back. It showed USB after the change (and re-entry and re-power afterward) but it still occurred until 3 or 4 power cycles later when it suddenly began working properly. I checked the configuration screen and it remains USB but the frequency is again proper. I tried the experiment again to confirm and, Yes, it causes that problem. It takes several power cycles to make it recognize the change back however.
The CW-R function does not do anything at all at the time (and completely unimportant) and is the reason that I tried the aforementioned option change. It may not be the RX BPF, but it certainly appears so. When changing bands now the transmit power is normal but the receive sensitivity is more than 20 dB down. It requires nearly a microvolt to be heard at all. Jogging the tuning up or down a click and returning it restores the normal sensitivity every time. Yes, for some reason 40m band change is problematic for both the double-click band change or changing bands in the RF sweep on the terminal. Easily overcome by using presets or, in the case of the terminal, physically setting the radio to another band before doing the test. Just a slight annoyance. Changing side tone frequencies doesn't seem to work. The S-meter works very smoothly but the maximum increment is 999 and still is full scale at 3 uV (-97 dBm) on 40m. Quite generous. And very unimportant. Keying is smooth with even the battery monitor on. Well done! Don't burn yourself out on this stuff, Hans. We appreciated the hard work but you need some time to yourself. I only bring this stuff up to your attention because you might be interested. I am NOT complaining by any means! This is a great project but it is just a fun thing and not serious whatsoever. 73, Don |

Hi all Let's not forget QCX' birthday! The original QCX was designed for the YOTA summercamp buildathon hosted by the RSGB in early August 2017, followed later in August by the public launch of QCX, I believe 21st August. QCX was replaced by QCX+ in May 2020, not everyone liked the larger size so along came tiny QCX-mini in December 2020.? The enclosure for the QCX-mini was actually based on the same enclosure extrusion, with different CNC machining and laser etching, as QDX - though QDX development was still a secret then, QDX was not launched until the following year in October 2021. Of course the new QMX is in an almost identical enclosure to QCX-mini too, having different right panel and laser etching only.? As of right now, QCX-series sales have reached 19,988 and will surely pass the 20k mark before it's 6th birthday, regardless of how one chooses to define it's 6th birthday (Start of YOTA summer camp? Buildathon day? Public launch?).? QCX+ and QCX-mini remain in my opinion, an important educational tool, I think a monoband analog CW transceiver is a great introduction to kit-building and a useful learning tool, and though QCX-sales certainly took a hit, I have no plans to retire the QCX-series despite the hi-tech QMX.? 20,000 sales! Quite a landmark!? Long live QCX! 73 Hans G0UPL |

¿ªÔÆÌåÓýHans,If I could add something regarding the filter sweeps. Here is has started the sweep and stops somewhere about 30% in some cases or 18% in another case. Been doing this for some time. Only on 40M and 60M presently. 73, Cliff, AE5ZA

Re: #QMX firmware 1_00_004

Hi all I fixed it, see version 1_00_005 see A single little typo :-/? ?After fixing that, testing on 20m with WSJT-X in FT8 mode, QSO with SP8NFO immediately on the first CQ. Dan... I wasn't able to reproduce the other things you mentioned but I think that at least some may have been side-effects of the main issue.? ? * CW is still not usable on -004 now because the receiver is listening 1.5 kHz lower than it's transmitting. CW-R is now not doing anything that I notice: Both transmit and receive frequencies do not change (aside from that fixed 1.5 kHz offset) and the sideband does not change. All bands. I was not able to reproduce this. I have a -60dBm calibration signal source that is on 7,003,513, measured on a frequency counter. I tune to 7.0035 and I hear it. LOUDLY. Then key (straight key mode) into dummy load with the frequency counter attached - it measured 7,0035 too...? Remember that you can only use CW when the radio is in CW mode. And only use Digi when the radio is in Digi mode. And yes I need to think of the nicest, least intrusive way to use a little piece of the limited screen real estate to indicate to the operator which modulation mode he is in.? ? * The receive BPF does not switch to a newly selected band until you toggle the tuning but the LPF filter now seems to be recognizing the shift (Thanks!). I couldn't reproduce this either. Actually on studying the code again I could not even see how such a thing as setting the LPF but not the BPF could even be possible. They both get setup in the same place in the code, the same function. So... ARE YOU SURE? ? * Attempting to change bands after a filter sweep if you start on 40m seems to lock it up still however now I can work it all fine if I start at 30m. (Getting there!) Now this is quite possible - I need to check that filter sweeps put the radio back in the correct state (previous state) at the end of the sweep. Quite possibly something is a little off, here.? 73 Hans G0UPL ? |

Hi Ken,
I can run FT-8 multiple rigs in WSJT-X on a single PC by creating multiple instances of WSJT-X ?through establishing independent shortcuts on the desktop and using the -rig switch. More details on my experience is here, if you interested: 73! @Linas_LY2H |
