FedEx express shipping 3-4 days now available; and other shipping changes

Hans Summers
 

Hi all

I have always collected statistics on shipping times to help manage people's expectations, see http://qrp-labs.com/shipping - but, nevertheless in these days of Amazon Prime etc., people sometimes have high expectations! Several people have requested faster shipping options but until now it has been too expensive. 

However, I have now reached an agreement with FedEx (TNT) on a deal for fast shipping of QRP Labs products at reasonable prices. I also tested it on two orders to US, and one order to UK. All three test cases arrived in 3 days exactly as predicted by the FedEx representative. So we will now offer this FedEx option, for people who wish to get their orders more quickly, in addition to the existing post office shipment option. To start with, FedEx local courier will collect from us on Mondays, Wednesdays and Fridays. Therefore, we will prepare all orders within 1 business day as usual, and then shipping via FedEx would take 3-4 business days (depending on what day you order). 

The prices for FedEx are higher, but not by a very large amount; in some cases the prices are almost the same. While post office pricing is adjusted in increments of 10 grams, the FedEx quotations are in increments of 0.5kg. There are no bad tax or VAT implications to choosing FedEx instead of the ordinary post office shipping. 

I have also analyzed the existing post office shipment prices and found that for small lightweight shipments the shipping amount charged by the QRP Labs shop doesn't cover the actual post office shipment cost, let alone the packaging materials. So in the case of some small orders I actually make a loss. To fix this I have now analyzed all shipment rates and increased the shipment price for lightweight orders. Some of the larger weight orders, the price has been REDUCED. 

However, I also decided to add a new cheaper shipment option, which is basic post office airmail shipment, with no tracking and no insurance. It should not be slower than the ordinary post office option, but, if it IS slow don't email me and ask me where it is, because it isn't tracked. This could be useful for people making small orders. 

Since FedEx is priced locally in euros, and the post office in Turkish Lira, I will have to review these prices from time to time and update them to take into account exchange rate fluctuations. 

So to summarize there are now THREE shipment options in the QRP Labs shop:

1) FedEx Express, 3-4 days; for orders weighing from 0 to 10kg

2) Normal Post office airmail, registered/tracked (the CURRENT option); for orders weighing 0 to 2000 grams

3) Post office airmail unregistered, no tracking, no insurance, no nothing - for orders weighing 0 to 250 grams

EXAMPLE 1, a small order (QCX firmware upgrade chip):
Order value $6
Shipment options:
1) FedEx 3-4 day express: $10.83
2) Post Office airmail $6.00 (current option, would previously cost $5.00)
3) Post Office airmail no tracking/insurance: $3.40

EXAMPLE 2, a QCX kit on its own:
Order value $49
Shipment options:
1) FedEx 3-4 day express: $10.83
2) Post Office airmail $6.96 (current option, would previously cost $7.00)
3) Post Office airmail no tracking/insurance: $4.35

EXAMPLE 3: a QCX kit with QLG1 GPS and 50W PA kits:
Order value $101.50
Shipment options:
1) FedEx 3-4 day express: $10.83
2) Post Office airmail $10.71 (current option, would previously cost $13.00)

all ferrite rings have some scatter and the inductance must be adjusted with an L meter.
I got 14 turns of L1 and L3, 16 turns of L2, L4-9 turns.
power (r&s fsh3) 12v-3.45w, 14v-4.92w, 15v-5.25w, 16v-5.94w.
current TX 12v-0.535a, 14v-0.628a, 15v-0.663a.
good luck!

With the Fluke, after keying up without using the on board first, the voltage stayed steady at 1.7, but if I checked it with the on board, it would read 0 just the same after keying.
Greg,

That appears to suggest the on board meter is wrong, maybe a bad soldered joint.

others were wildly off. Particularly IC7, 8, 9, and 10.
? You mean pins 5, 6, 7?
If so this is not possible, you say pin 1, 2, 3 are correct, look at the schematic, that section of the IC is fed from pin 7.

Then the LCD is off oddly, but still works fine.
I'm not sure, 2 of those connections are not used. Recheck, check soldering.

There is no RF at Q1, Q2, or Q3.
Check voltages on Q1, 2, 3, 6, RX and TX.

Is the radio dead?
Does the RX work? Have you gone through the alignment?

Do I need to scrap it and buy/build another one? (I don't mind, I love building these things.)
I'm sometimes a little upset if something I've built works with no problems! Part of the fun is finding the faults and learning in the process.
Nothing you can build is beyond repair.

One thing that many find is bad soldered joints, go over any that might look bad.

I don't know why that sent already...


OK. I posted this once with a few measurements using the on board test equipment the other day. 

Tonight, I began to go over it again taking all measurements, again with the on board test equipment. I began to get weird readings, so I broke out my Fluke 77III and checked those voltages again. They were definitely off. I checked Clk1 and with the on board it was varying, but went to 0 after I keyed up. It wouldn't show voltage again until I turned the radio off then back on again. With the Fluke, after keying up without using the on board first, the voltage stayed steady at 1.7, but if I checked it with the on board, it would read 0 just the same after keying. 

For example, Clk 0 on the on board, was varying between 1.53 and 1.81. On the Fluke, it was rock steady at 1.70. So, I used my Fluke to take all the measurements listed below. 

I will list them as they are on pages 128 and 129 of the manual. 
Here are all the measurements. This is with a power supply at 12.72 volts.

Some measurements are dead on, some were slightly off and others were wildly off. Particularly IC7, 8, 9, and 10. Then the LCD is off oddly, but still works fine. 

There is no RF at Q1, Q2, or Q3. 

Is the radio dead? Do I need to scrap it and buy/build another one? (I don't mind, I love building these things.)

Any help to revive the radio would be greatly appreciated, if it isn't dead.

Don, most of the time on the 20 meter version this has been an issue due to the lowpass filter cutoff frequency being just a bit too low. Folks have found that if they remove a turn or two from each of the 3 LPF toroids (L1, L2 and L3) that the power comes up to something more reasonable. I’ve done this on several 20 meter ones that were low in power. Lift one leg of each coil and unwind a turn and then just solder it back to the top of the board without cutting it off, for ease in testing. Then when you get it where you want it, trim the excess lead lengths and solder it back in the hole or just solder on top of the pad. Since this is a plated through hole it will work that way too. I usually see an avberage of around 3.5 watts out on the 20 meter QCX. Some have been higher and some lower. 3 watts is really sufficient power on 20 meters for some good contacts. 

 

Good luck … Ron

QCX Message Editing

Tom NM7TS
 

I have a QCX-20 and QCX-40, both running firmware version 1.03. Today, I experienced a problem editing stored messages.

At the end of section 4.18 of the  manual, the Enter (finished) symbol is described. The manual states that selecting this symbol and pressing the left button will save the message and delete everything to the right of the symbol. However, I had some text (left over from editing) to the right of the symbol, and it was not deleted. When I tested the message, all of the unwanted text at the end of the message was also played.

I removed the unwanted text manually, using the Backspace (delete) symbol, but it seems there are still spaces after the end of the message. I have the repeat option set to 10 seconds, but the message does not repeat until much later. I suspect this is because of remaining spaces.

It appears that the Enter (finished) function is not working properly. Both of my QCXs exhibit the same symptoms.

Has anyone experienced this problem? I'm hoping that someone running version 1.03 and someone running an earlier version can test this?

That sounds like a great tool for production work using RG316. But I find that 316 is comparatively easy to prepare using my regular method of circling the jacket with a sharp knife. I say comparatively because the jacket material is soft and the braid is fairly resistant to nicking, relative to other cables I've built with. RG213 jacket is also very soft but as has been hinted, the braid is delicate. JS6TMW

To Safely Prep Teflon Cables you need a stripper that uses two blades attached to Heat Source that when squeezed shut, heats up the blades (with a notch in the middle) to safely cut the insulation w/o damaging the center conductor. I used one when I worked at a place making Solid State KW+ Amplifiers. Once you use one you will never go back.

Hi, One of the old problems on first switch on things were normal, after this a single row of blocks, I have read the possible cures and remedies, I have tried 3 different processors revision Ti.03 on a revision 5 board, I have checked the soldering to the processor and so on, voltages left to right on mounting ins= 1, 0v,  2, 5.04v,  3, o.42v,  4, 0.07v,  5,0v,  6, 0v,  7, 0v (8/9 not used)  10,0.02,  11,2.43v,  12,5.03v,  13,0v,  14, 0v,  15, 11.82v, 16,0.v using a DVM, voltages are nowhere near those quoted.

I experienced the same problem with my QCX 60m. i
It was working well but was  only putting out about 2 watts so I started poking around to measure voltages and power when suddenly "puff" and I had shorted something.
Voltage regulator was getting very hot in short time so I cut the output connection and measured 5V at output and the QCX would light up but obviously nothing was working sodetermined a short in 5V line.
A laborious process of elimination identified the IC4 FST 3253 as the culprit. I managed to it (and voltage regulator) using a small Antex soldering iron which was great challenge and learning curve.
However, I now have a working QCX still putting out 2 watts.
It sounds like you have some good local support but if you have any difficulty sourcing parts (RS online ?) or want to ask anything please do hesitate to contact me.

Good luck
