Nice! She even added the capacitor for the voltage regulator!

Hans, you were way ahead of the culinary world with your method. This is now an accepted method for cooking exceptionally good pasta. You may want to ask your wife to add that to the story :)

Re: QCX original #sidetone problems above 16 WPM #sidetone

Alan G4ZFQ
 

Any ideas where I should look or what could be causing this side tone drop out which makes sending impractical unless very slowly on the built in key?
Lou.

Does it happen into a dummy load? Any antenna configuration can result in RF in the shack, maybe on just one band.

Why do you assume there is something wrong with the blue pots? The adjustment is critical, other things can affect balance.

QCX original #sidetone problems above 16 WPM #sidetone

 

My old QCX original from 2017 I recently altered LPF coils and capacitors from 30m to 20m.
The RX is fine with great sensitivity.
The TX is fine with 4W out at 12V, 5W at 14V. 
However, when keying either with built in key or in keyer mode with external key, the side tone drops out on every 2nd dah for example, but only if about say 16WPM. Below this speed it sounds a bit clipped or delayed. Above this speed, it just can't keep up and drops in and out. 
Continuity is there from the end of L3 through to the antenna socket.
It is not an RF problem in the traditional sense at least (antenna feedback) because the antenna is a balanced and resonant antenna caused no problems whatsoever on other QCXs before, nor on this one. 
I did as mentioned replace the band dependent capacitors, salvaging them from another broken QCX. If one of those capacitors is not ok after having removed it and put it in (I have no way to test capacitors), could that cause this effect?
There is absolutely no power variation on transmit, even when side tone drops out, power is solid, stable, very steady. 
Everything else on the rig seems to work fine, except for the 3 pots that are tuned via menu 8: the side band rejection and insertion pots: those, have little to no effect when trying to tune them, unlike on all other QCXs i have built, and have been like that also prior to this side-tone problem on this QCX. 
I assume something is wrong with one or more of those blue potentiometers, given little to know variation, or at least with the 2nd and 3rd one. 
That said, strong signals produce opposite sideband not being rejected, but normal signals have little to no opposite side band so there is some effect.
I mention this only as that is the only thing not working as expected on this rig, otherwise everything else is fine.

Any ideas where I should look or what could be causing this side tone drop out which makes sending impractical unless very slowly on the built in key?

Congratiolations on your birthday Hans.  The cake looks great and hope you had a day to remember. 

 

And being semi centurian, there is no shame in  loups and magnifiers. Just take comfort in the idea that the QRP generation will need glasses much sooner then us because of them looking at small screens the entire day.

Many thanks all for the kind wishes

I was mistaken, the QCX+ in question (upon which the cake was modelled) was a 40m not a WARC band (30m) version. Evidently when you reach a half-century you have to accept that you can no longer see anything anymore without loups and magnifiers, including mistaking 5-turn T1 secondaries for 4-turn... 

Onwards ever onwards...

My mother was a radio operator for the UK Special Operations Executive in WWII. When I was a kid she gave me her Morse key and a book called "Mastering Morse" (I still have them). I passed my amateurs exam aged 15 but never managed to master Morse.

Now in my late 60s I'd like to try again so I'm following this discussion with interest!

I just received one about three weeks ago. It’s the latest version with upgrades. It’s available. You just have to find the correct site.

I'm not sure, but I don't think the Morserino-32 is available anymore. My guess is that the reasons are because the cost was pretty high ($110 US) and the shortage of chips.
For information: Morserino-32 is still available and despite a higher price (85€) more than 4000 units have already been sold.

Re: QRP Guys SWR/PWR meter

David Wilcox K8WPE
 

They had run out of the red filters when I received mine but the display is a nice red without it.  On their other kits that they sent the red filter with I used a dab of E6000 available at hobby shops, Hobby Lobby, etc. Just a drop on each edge and it spreads out as you press the filter on.  Some places sell PFM but it used to be more expensive. They are the same thing, a rubbery glue that remains slightly flexible. I first learned about it when using it to glue in electric motors to a RC speed boat.  It is like the clear marine sealer that one uses on aquariums.  I think very similar.  GE clear caulk works if you have some setting around from a caulk job.

They also mentioned when I questioned them that the red filter material is available from florists, if your town has any left. Sam’s, Walmart, etc., seem to have taken over the florist business around my town.

Re: Problem with PA 5w qrp lab

KEN G4APB
 

Hi Joseph, you asked this question before, did you try my suggestions below?…

Stray rf into the display can cause this, especially if you are feeding the 5w back through the U3S onboard lpf. Are you running the U3S at 12v too? 
Make sure your 5v supply to the U3S is very well decoupled.
Run some extra thick earth wire connections between psu, PA and U3S and casework.
Use coax to feed the 5w signal in and out of the lpf, NOT unscreened wiring as shown in some application examples.
if using the qrplabs supplied case for the u3s, the anodising can make poor earth connections, so i took mine apart and made sure all panels connect well, including antenna connector.

I made my cw contacts at age 69.  I wanted to learn cw and put some contacts in my log. I do the things in Ham radio that are not generally easy and use it for a mental challenge and to be there in case of an emergency. I have let it lapse and will go back to LCWO as it is free and learnable.

Have made ft8 contacts but keep the sound turned off and just click a few times. Like watching paint dry.

For QCX+ affocionados...

On the occasion of the OM's, er, um, eh, ahem'th birthday... the beloved XYL baked a delicious surprise QCX+ cake. With 5 candles... er, ahem, one for each year after 20 (!!)... we ate it with our six employees and extended family and various friends. I'm sure QCX+ aficionados will be able to recognize the cake "PCB" component layout.
