I wonder how hard it would be to add Bluetooth support so one could listen via that way instead of having to use regular headphones.

Is that a suggestion that we need to spin-off annother group for "Homebrew Test Equipment"?
To aid in building BITX equipment I have built several Arduino based test sets.? Others have probably done simimar designs and builds.

I don't agree with the ' don't care bit' but we should all move with the times. Maybe heads could be put together to come up with some inexpensive test gear in kit form that gives a simple spectrum analyser/wavemeter, RF power meter, 'scope combo to complement Hans kits. A bit like a radio test set you can get professionally. Ideas guys and gals? 73 Ken G4APB

I'd also like to see a quick tune function. However, changing the keyer mode to straight, tuning up, then changing back to iambic is actually pretty quick. This is one case where it's a shame the software isn't open source because then I could add the feature myself.

I didn't RTFM and this is indeed explained in the manual. However, it's inconsistent with other functions e.g. section 4.11 explains that the right button saves a changed menu item. I had assumed that RIT worked the same way.

Really pleased to see Hans is moving forward with an upgraded kit to the QCX.? The video lays out all the wonderful features.? It should be a great kit and a big seller.
I'm a big fan of Elecraft but I've been hesitating to pull the trigger on the K2 kit due to the high price.? I want to get one before production is stopped, soon I imagine.? But I suspect the QSX will provide significant market pressure to reduce the K2 prices, especially if 10,000 QSX kits are sold in the first year.? Or the popularity of the K2 may cause production of the K2 to be ceased altogether.
I'm sure Hans has a mailing list of QCX owners.? It would be appreciated if he could mass-email the announcement the QSX kit is available.? I'm confident he'd have several thousand orders within ninety days.

The LCD I speak of is really attractive, professional looking even.

Here¡¯s one vote for an LCD touchscreen like KD8CEC (think that was the call) did for the uBitx...

. What is the proper key sequence
in order to get output it seems that this was over looked in the instructions? Is their any way
to use the serial monitor to force it to a selected output frequency? Joe, The sequence is explained in the manual, I reckon I had to try several times before I got it right. Fill in Han's chart and take it steady. The serial connection makes it easy to set the memories but again even after reading Hans' superb instructions It took a me few attempts. I do not remember for sure but I think you can only program the memories, not set the frequency on the run. 73 Alan G4ZFQ

Thanks Alan,
I'm using the Arduino serial display and now can get whats stored in each register setting
but when checking the SI5351 output only get 27 MHZ. What is the proper key sequence?
in order to get output it seems that this was over looked in the instructions? Is their any way
to use the serial monitor to force it to a selected output frequency?
?If I can get this device working I plan to us it on 2200 and 630 meters as a replacement for
xtals that I now use in a resistive SWR antenna tuner signal source to replace two units
with one.

Re: Volume control and S-meter interaction
#qcx
Hi
Yes - it's normal.? Page 96 of the manual:
"The S-meter reading is indicative only, it does not have any highly accurate meaning. In any case
the audio sampled by the Analogue to Digital converter is after the audio amplifier gain stages so
the amplitude depends on the receiver gain setting."

Re: Homebrew HF geberal coverage receiver with SI5351 VFO & Progrock
Ohh, that looks a lot like a project I've been thinking about and sketching on envelopes but have yet to put solder to, any further details?
Hi to All, attached some photos of my new HF receiver built with the SI5351 VFO and Progrock...very nice and useful circuits.
The receiver is a double conversion, 45 and 9 MHz, general coverage.
Thanks to Qrp Labs for homebrewer devices production.

There's not much you can invent these days, that hasn't already been done ... this might be what you're looking for, although it is not available in kit form ... yet.
Watch this !
and?

I agree it would be useful to have a tune button. but I simply tune on another radio and switch back to the QCX. I have a home brew antenna/radio switch box.

I've been off-air for about 15 years now and have spent the past couple of months looking over modern high performance kits and circuits that would cover SSB and this has already ticked all the boxes for me (price being a big one of course) - I'm already visualising enclosing one in the style of the KX2 / KX3 and Xiegu, etc.? For the feature list and proposed price point, I truly reckon this could be something of a giant slayer.? Watching with excitement!

" the majority of hams?building these low priced kits are doing it with nothing more than a soldering iron?"??????

In 1979 I built an HW8.? I didn't have a voltmeter or an ohm meter, just a soldering iron, a brain, and the discipline to follow instructions.? When I finished it I handed it to a 33S, those familiar with the MOS system will know that as an Electronic Warfare/Crypto Repair Tech, he aligned it.? Other than that he made no changes.? Now then, I say that in defense of the literally thousands of other HAMS, who might have a multimeter, a soldering iron, a brain, and the discipline to follow instructions.? I had a multimeter this go round.? The instructions for Han's kit are superb.
It is patently arrogant to suggest that someone who may not be as "advantaged" as some person who does have a nice bench cares less about the air waves than someone who may, in fact own a nice bench but not have a brain...
Bandwidth wasted... mischief managed. W4MHZ, 98G, 73 ;)

Anyone have the fuse settings for the ATTiny 84 chip? Joe At the bottom here are my notes, also read the link to Han's definitive explanation. 73 Alan G4ZFQ

Agreed, the RTL dongles need to be used with care and an understanding of how the various settings affect what you see on screen and hear is essential but they are considerably better than nothing.?
I¡¯m spoiled by having some rather sophisticated test gear at hand but a receiver is a very useful piece of kit that every constructor should have access to if they¡¯re building transmitters, a signal that ticks all the boxes on the test gear can still sound dreadful on air as well.?
> I would suggest one of the RTL SDR dongles
? Clint,
Even that would be better than nothing.
It surprises me that some do not even have a RX to check what their TX
is doing.
While the dongles need to be used carefully they do act as a poor man's
spectrum analiser.
