US post office shipping rate increase

Hans Summers
 

Hi all

Most US customers will now find it cheapest to choose the FedEx Express (TNT) option at checkout. FedEx Express (TNT) rates are unchanged. 

Non-US customers post office shipping rates are not affected.

Regrettably we had an unpleasant surprise this morning, we received a phone call from our local post office asking for 670 TL additional payment for the packages we posted yesterday - this is approx US $100 - the reason is that overnight, the rates for posting packages to US have literally TRIPLED. 

Further investigation and some Googling reveal that this is a result of US foreign trade policy changes under the current administration, specifically in regard to international shipments, the USPS are charging foreign post offices a much higher rate for the US handling of incoming international packages. The origin post offices therefore have to pass this on to their customers. 

As a result we have incurred significant losses and it comes at an unfortunate time because we have the backlog of QCX+ orders that we are working through. Anyway, these things happen, life goes on. 

Accordingly I have had to set up a separate shipping category in the shop for US post office shipments, henceforth unfortunately the price of US post office shipments has risen dramatically (approximately by a factor of 3). 

QRP Labs policy remains to charge all shipping at cost, as closely as we can. 

Most US customers will now find it cheapest to choose the FedEx Express (TNT) option at checkout. FedEx Express (TNT) rates are unchanged. 

The only time post office shipment is cheaper is for small lightweight packages, under 120g (registered/insured/tracked) or under 250g (unregistered/uninsured/your risk). Even then, the price difference is so small that generally for the speed, FedEx Express (TNT) will be preferable for many people. 

Note that in order to minimize our losses, we will in many cases promote existing pending QCX+ orders where post office shipment was chosen, to FedEx Express (TNT), at no cost to you of course.

QCX+ alignment: attempted murder of my SA

Giuseppe Marullo
 

Well,
not by a long shot but...I was surprised when I hooked up my scope the the RF output. I have about 2.8W so wanted to check.

Is it the signal generator function that injects DC on the output all the time?
Any recommendation for a DC blocking cap for it?

I am not comfortable with 5VDC offset on the RF connector.

Re: Shipping Estimate for QCX+

Greg Walters
 

Howdy Hans, and all,

I ordered my 80 meter QCX+ on May 15th, and got the paypal receipt, but not an order confirmation from QRP Labs. 

I don't have an order number associated with the Paypal receipt, so I am hoping that it actually processed. 

Were order numbers and emails sent out with the orders?  I just thought to check my Spam folder and it cuts off at June 12th...

Not angry, just curious where I am in line to get my next QCX...

Thanks, People, for all your prompt and helpful responses.  I have printed out Fred's words of wisdom plus Rick's pdf.  As a matter of interest, my firmware is c1.02.

Will re program my clock display after a good sleep and feeling fresh!  Otherwise the likelihood of pressing the right button when I should have pressed the left button or vice versa will result in a loud expletive.

Again, many thanks, 73 to all.

Re: BPF too good? #filter

KEN G4APB
 

Your results will depend on what other losses you have taken out in the CAL. The 4 pole non-50 ohm connections to the filter should NOT be calibrated out if you want a true 'in circuit' reading as they appear in the actual U3S. I found if you measure filters in-situ, especially if you start using the switched relay board with multiple filters (BPFs), the filter responses soon become misshapen and losses increase rapidly. I measure some 5-6dB in circuit losses in my mutiband U3S Rx.
Having said that, your tune and test up method looks good.

I just saw this in the manual
"4. 08-Oct-2018 Firmware c1.02a release, having the following features explained in this manual: Support for 4 x 20 LCD"

It does not seem to be documented, I must try what Fred says.

Re: Clock Display

I too have a QRP Labs shack clock with QLG1 GPS connected. I also fitted mine with the 20x4 display.
I found that the 16 column format was only evident during the configuration phase of setting it up. What I mean is that when you are in the menu and configuring the data and labels you want to display on each line, on first getting into the menu system only 16 columns of whatever is already stored, is displayed. If you continue to step one character at a time to the right, then the rest of the configuration line gets displayed. All the values are there - they are just not initially displayed. In fact a line of configuration can have much more than 20 characters with the 'line break' solid block character allowing you to specify different data on the line. 
Once configured, when in normal operations, mine will display data across all 20 columns.
I think I am using an old version of the software - V1.01. I think the current version is 1.03c and it offers more data to display. I need to get around to upgrading mine.

How do I tell the clock that it has a 20 x 4 LCD?
Kevin

I have looked for that to suit my 20x4 clock display.
I can see no setting in the menu as there is in other QRP Labs projects that I have not fitted a 20x4.

Clock Display

Kevin Luxford
 

I am very sorry to have to ask the following question. A couple of links to further information within the operation / assembly manuals are broken, and a search has not turned up the information I need. I have built the clock. It uses a qlg1 GPS receiver to provide satellite data to the clock. It works. However, the display, which is a 20 x 4, will display 4 lines of output, but only up to 16 characters per line. How do I tell the clock that it has a 20 x 4 LCD?

And congratulations to Hans and his family on the arrival of the 2nd harmonic.

Re: QLG1 GPS - No TXD

 Hello Mike,
 
the yellow (TxD) LED should start blinking after power is applied.

QLG1 GPS - No TXD

Mike Besemer - WM4B
 

Greetings all,

Working on a QLG1 for another gentleman and would like the opinion of others.

Initial symptoms were that the Power, TXD, and PPS LED all remained on at all times.  I received the board in the mail today and went straight to work on it.

A quick check with a scope revealed that there was no TXD or PPS output from the GPS RF Module.  I then proceeded to touch up all the solder joints, followed by a good cleaning with brake cleaner and a toothbrush.  This resulted in no change (as expected).

Based on measurements taken by the other gentleman – and my gut – I then proceeded to remove and replace IC1.  (I actually replaced it with a socket, to facilitate further troubleshooting.)

With the IC removed from the socket, I still had no TXD or PPS signal and began to suspect the RF Module, but a quick continuity check between the Patch Antenna and Pin 11 of the RF Module revealed a questionable connection, so I sucked that joint clean, scrubbed it, and resoldered.  A minute or so after reapplying power, I started to get a good PPS signal, but no TXD.  With IC1 installed, I get a flashing PPS LED and no TXD LED.  (Power LED is fine.)

If I remember correctly, the PPS signal should not be present until the constellation data has been downloaded and TXD is available and being sent, so I have to *ASSUME* that the RF Module is working insomuch as it has the ability to receive and decode GPS data.  That being said, it is still *NOT* producing TXD.

So the question is:  Is the Rf Module toast, or is it a firmware issue?  I tend to think the module is toast, but I’m not that experienced with chips that contain firmware.  I *COULD* drag out an rPi and monitor, download the image, and attempt to reflash the module, but before I go through all that thrash, I’d like to hear from others who may have been down this road. 

I’m aware that there is a pin-for-pin compatible replacement for the YIC, but IIRC, it costs more than the entire GPS.  I have the ability to replace the YIC, but I don’t know if it could be sourced from Hans or if that would be cost effective. 

Ideas?

One way to use it to label a front panel would be to make a vinyl covering for the entire panel, cutting out the labels and holes for controls.”

 

That was my method, but I only cut out the lettering for the labels.  The holes were formed with the tip of a hot soldering iron.

It's a computer-controlled cutting device. The fancy model will cut a large variety of soft materials, including basswood and leather. Not metal, though.

It's also possible to put in a marker rather than a cutting tool. It might be possible to label a front panel by using the market to write on it. I make no promises about how well or badly that would work; the markers might not be designed to stick well to front panel materials.

Hi Ted,

 

No… a Cricut machine is a toy for (mostly) the XYLs.  It cuts paper, vinyl, etc. and produces some really intricate patterns.  I still need to re-cut my the overlay for my front panel… the XYL has been using (her) toy and won’t let me in!

Re: Horizontal lines after power up

Jim Netwal
 

I am now convinced that I have a bad screen.  I took the screen from the QCX 40 and put it on the QCX 20 and it seems to be working fine.  I was able to do the alingment on the radio and I am receiving signals.  It's been on for more than an hour now and it's working fine.  So now the questions is where can I order a new screen from here in the US?

Thank you!

Toroids are self shielding, as almost all the magnetic flux is enclosed in the toroid.  There may be some capacitive linkage to the nearby metal, but it would be very minimal.

I built a 20 m BPF. Since I have many to make, I made a holder with SMA connectors and decided to use my recently acquired  NanoVNA for the first time with a filter. Filter analysis shows a center at 14.09 MHz and a 3 db BW of 1.39 MHz, which seems fine. Neither variable cap is at its extreme.
My concern is that the loss looks too low. I'm seeing 0.4 dB S21 loss. The VSWR is also 2. After calibration check with straight through wires scan reads VSWR 1.03, return loss -35 dB and S21 gain -.077 dB.
