Re: QCX Displayed Frequency vs CW Offset #qcx #manual

How I calibrated my qcx 40 was to listen to 7.0475 and compare both sidebands I adjusted the frequency calibration until I got the tone the same by ear on both upper and lower sides.

Although not true laboratory grade I figured that the ARRL transmitter was as reliably close. as anyone.

You could use the I and Q signals. Port them to your computer's sound card. Then with SDR software you got a waterfall display.

You could just monitor a WebSDR station near your QTH with a computer or tablet. Then you can literally see any new signal pop up and tune to that. If CAT control would let you change frequency (I'm not sure the capabilities of CAT yet), then the computer control could then set the QCX frequency for you.

Re: Scanning feature for QCX

I wasn't thinking about any feedback mechanism that would dwell on an incoming signal,
just starting and stopping by hand so you don't have to sit over the radio and turn, turn, turn to see if the band is open.
That would be very simple and a quick practical implementation. I don't like jostling the little radio each time I want to go from 14,000 to 14,065
or 14,045-14,065 listening for activations, etc.

 A modest request for semi automation ( hi hi ) Now I go to the 1 khz rate, but notice that i do this
manually every few minutes as the band in the recent past goes open for short times and it is easy to miss activity.

You can learn a lot by listening to the band and you don't need WSPR or an SDR . For me it is music.

Great idea, not likely to happen. The firmware is already "full up." If enough present features were removed, scanning might be possible, though I doubt many would support this. On the other hand, Hans is quite the wizard, so he might conceive of something.

As an aside from an old family Doc, the tonic water would also eliminate the night time leg cramps many of us old men get. Used to prescribe quinine tablets for that but too many side effects so are no longer available, only for true malaria. Also were available for about $5.00 a bottle. Now are $3.00 a tablet. I keep checking the tonic bottles at the grocery store but none tell how much actual quinine is in each ounce. But, with the gin added who cares?

Re: Scanning feature for QCX

Hi George

I'm wondering how useful it would be in practice. How long should it stay on each frequency? Presumably long enough that you could react, drop whatever you were doing, and jump on the radio to stop it from its scan, so you could work the station? How long is that? Configurable? 

I'm not saying I have time or space to put it in the QCX code necessarily... I am just wondering, how such features are normally implemented in order to be useful and practical.

The difference between these cases and the real Peli cases that they lag the Automatic Pressure Equalization Valve.

But I have several of these chines cases and for me they work. I use them to transport my rigs and other equipment in and also have a small one packed as a FT817 field-radio go kit.

Hi Jim
there sone fields you have to turn on. Make sure the Alarms Enabled is ON, ensure in the alarm timing line you dont have dashes shown. Also make sure your alarms are set to trigger on Local Time.

Re: QCX Displayed Frequency vs CW Offset #qcx #manual

Hans Summers
 

Hi Dan

The displayed frequencies are always the actual transmitted frequency. 

During receive operation, the 700Hz offset (or however you configured it) and the RIT are added to the displayed frequency, and the result is the actual frequency the synthesizer is set to. This is correct convention. 

If your display reads one thing but your transmitted frequency is different, then the next question is, have you calibrated the reference frequency?

Is the upper left displayed frequency  A)  during receive mode  the transmit frequency or B) is it the transmit frequency netted with the offset frequency in the receive mode.  I thought the displayed frequency should always be the transmit frequency as in A. The manual indicates the cw offset is automatically applied or netted as in B.

I have adjusted the audio filter to center on 600 Hz.  The VFO CW offset is set to 600 Hz and the Keyer CW tone offset frequency is set to 600 Hz.  The audio alignment frequencies were also set accordingly. 

Using the Reverse Beacon Network to verify my transmit frequency when I adjust the display to 14.050000 the transmitted signal is at 14.050600.  Is this correct and  what I should expect or do I have something wrong in the setup?
