Why do you operate in a gravel pit? Doesn't that block all the signals except for NVIS? Just curious about your experience with that. Thanks.

Re: Shipping: "Buyer Centers Opens Bag" - problem?

Hans Summers
 

Hi Jack, all

I can only recall ONE instance of an item being missing altogether from a QRP Labs shipment, and this was due to a heavily damaged box that got water-logged and broke open somewhere on the way. I replaced the missing items. 

If any item in a QRP Labs shipment is ever damaged in transit (which is extremely rare) I send a replacement, no questions asked.

This caused me to look at the label on the bag. It had no Chinese markings on it whatsoever. This makes me think that the order was opened for inspection in the US and then the contents just tossed into a bag, a new label printed, and I got the results. I have no proof that this is what happened, but it squares with what I observed.

Re: Random Wire and no tuner.

 

It is a big wide open gravel pit area. Probably half mile across.  80% is woods on the sides. The owner lets me have free run of the place . 40M during the day I usually work into Europe , the Southern States, lots of East Coast. lots of South America during sunrise and sunset.

U3S display disappears over night

Chris Wilson 10 June 2019


My U3S has been permanently on bar a few off moments for months. I am
now seeing the LCD disappearing overnight. Powering it off and on
again restores it, but I *THINK* I can detect some mild flickering.
new display time? Thanks. BTW it continues running without the display
visible.

Re: ENAMEL REMOVAL

Hello QRP'ers,

Monday, June 10, 2019

I was lent some lovely old Litz wire with silk covering as no one
could strip it. Various potions filed until I read of using molten
caustic soda. Despite it eating my wifes Pyrex dish lid to an opaque
and rough texture it does the job perfectly, but you need to wash the
wire thoroughly after to remove any traces of the caustic. OTT for
single strand, but may be of use to someone at some time :) Usual
caveats, molten caustic soda is dangerous, blah blah....

Chris 2E0ILY mailto:chris@...

**********************
I used to own a metal finishing business and one of the jobs we did was strip PTFE coating from secateurs for Wilkinson Sword.

We used molten Caustic Soda to do this.

Workers used every piece of protective clothing, headshields, goggles, long gauntlets, we could find
and they STILL got caustic vapour burns on every shift.

Take GREAT care and use the very minimum amount practicable - it's dreadful stuff.

To my mind this is a last resort - try everything else first!

Hi Jack,

I am happy to see you testified about them replacing those parts. We hear so much negative stuff about the Chinese. I have yet to be dissatisfied here. None of the goods was ever damaged or defective.

By the way..my own copy of that Arduino book arrived:)

Re: Clock Kit 4 Line Display Case?

N7PH
 

The 4 line display is roughly the same length but aprox. 1/2" wider (taller). I built my clock with the 4 line display andI think you'll be more than pleased with the larger display. Currently my display shows L1 time Zulu, date, L2 time Local, altitude, L3 My call, locator, and state and L4 shows Lat/Lon on 4 sec cycle.

Thanks for the tip!  I'm curious what desoldering gun you use.  I see a number of cheap ones on Amazon, but not sure if they will do the job.

As mentioned, and totally coincidentally, I have the Haako 808 also. I'm a huge Haako fan; all soldering equipment I own is Haako, and along with that, their hand tools are just as high quality. The 808 has been discontinued, looks like the FR-301 is a similar item. Not cheap, but having tried a few of the cheap ebay/Amazon units before finally just giving in and getting the Haako, I can tell you it was definitely worth the money.

Iambic problem on QCX

LUC VLECKEN
 

I have a repair to do for a fellow ham:
following problem; IAMBIC (A & B) does not function any more. Strait key no problem.
Iambic connector tested, good.
But dash pin (18) works on the microcontroller, but dit pin not at all
Any ideas? Pin dit (19) of the MCU defect?

Thanks in advance 

I-Q balancer help #40m

russkydeutsch@...
 

Looking for help adjusting the I-Q balance portion in the instructions. It saus to do this within 5 - 10 rnge of values. But I can't get it to go more than 2. I've adjusted the multi turn resistor R27 and it still doesnt go greater than 2. I would appreciate any help. Thank you.

Re: Iambic problem on QCX

Alan de G1FXB
 

Assuming you have made physical and electrical checks and have proved nothing conclusive,
Pin19 is a shared pin with three uses, Dit, SCK, RXD, do any of the other functions work?


The easiest I would find on my bench is RXD, it is the NMEA feed in from the optionally connected GPS receiver.
The one test would be does the QCX clock set and the WSPR Locator fields get self populated if connected to a compatible GPS & menu settings?

Alternatively if you are confident in hooking up and using the ISP header,
SCK is Serial Clock and used during firmware read / write,
Don't try to write anything in case you over write something important.
Can you read anything back from the ATmega?

Dan Baker,

Two things to get best results...

Use a 1:9 transformer (unun) to match the antenna better.
Add a counterpoise  wire of any convenient length, though
around 10M should be enough.

AGC project

I see there is an article in July QST for building an AGC board.  Does not look like it would fit in a QCX box, but might be something to consider external.
