Greeting all?

I am involved with a VHF beacon project and for some time the team had settled on using PI4 plus CW as the Tx modes. We are now contemplating if FT8 would / could yield more reports / feedback being as FT8 is very popular.

As part of a pilot was thinking to configure a U3 to Tx both PI4 and FT8 plus CW but seems inclusion of FT8 has not yet been released.

Anyone care to comment / make suggestion(s) regarding U3S FT8 and or merits of FT8 vs PI4 (or any other modes)? ?Aim of project is as a tool to explore VHF propagation throughout South Africa.

There is possibility of using a RFZero as this unit supports FT8 but would be more acceptable to use the U3S that was built for this project.

Advance thanks for any and all feedback.

I'm wondering if I can use the Progrock2 with the QLG2 to form a GPS disciplined oscillator that I can use with my Adalm Pluto requiring 40MHz local oscillator?

Roger,

My tests indicated that the PPS modulates the output.
Just a little +/- 0.5Hz, but I'd be wary to use it for a reference.
I have just left it, no further checks, there have been a few other reports that have not mentioned that, maybe not noticed or not present? Or, just bad connections?

The real fiddly work has already been taken care of for you with the mounting of the SMD components. If you had to install some of those multi-lead packages on a PCB then I would truly despair.?

What you have to install are discrete components that are leaded; resistors, capacitors and transistors and to hand-wind the inductors and transformers. Your greatest chance of error there is a solder-bridge, breaking a component package by bending the lead too tight, installing something backwards, not getting the insulating varnish off of the enameled wire or confusing what lead is what on the six-leaded twisted transformer.

Use a good iron, magnifying light or optical loupe and a DMM to test for shorts or verify component values if you suspect anything. The instructions are very explicit and you need to read and understand every word as you follow it precisely. Maybe it would be easier to print out the assembly instructions and use a pen or highlighter to mark through each sentence as you do it so you don't skip steps or install the wrong component.

I started assembling kits when my father, who was a ham back in the 1970's needed someone with a steady hand and good eyes to assemble his Heathkit radios. My brothers had no interest in it but I did; and I am darned good with a soldering iron. The QRP-Labs radios are the easiest I have ever built with the most well thought out instructions.

I have used it to write C code. Does a nice job.

OK, so _sometimes_ it’s hallucinations _appear_ to make sense, but if it’s not trustworthy, then what’s the point?

Andre, why not put that question to ChatGPT?
Randy, K7RAN?

Even GPT agrees with me. Emphasis mine:

It appears that the discussion in the QRP Labs group thread veered off-topic into the capabilities of GPT-4 and its applications, including but not limited to ham radio and programming. You questioned how this discussion was related to QRP Labs, which is primarily focused on low-power amateur radio kits and radios.

To directly answer your question, the discussion about GPT-4 doesn't seem directly related to QRP Labs or its core focus, unless there's an angle where AI could be applied to amateur radio communications or the development of QRP Labs' products, which wasn't clearly articulated in the thread. It seems like the thread diverged into discussing the merits and limitations of GPT-4, rather than staying focused on QRP Labs topics.

In summary, your question about the relevance to QRP Labs is quite valid based on the information provided.

And that's what I would tell everyone as a provider of AI services whilst ensuring I was able to mine and use all the private data to train my model and make money off what the customers where doing.

Very interested in hearing about the "smoke test", and first usage!

I ordered mine yesterday!

Andre, WT9X

I am happy to report I finished assembling the main board in the QMX.? It was quite a rewarding experience.? Easy stuff left to complete in a few hours.? I decided to build for 12V because various sources of 12V power are much more readily available than 9V.? I just need to build up a "test" power supply for 7V and current limit at 250mA.? I have all the parts for it. The more challenging area was the crowded LPF toroid area.? Don't use too much solder here or you will be using copper braid a lot, and inspect carefully as you go.? I did use a heaver soldering iron for the joints that needed it, such as the BNC.? It was a Haiko FX-601-02, about 67 watts, light weight,? with a ceramic element. Not inexpensive, but has not failed after many years of use.? Just don't drop it or you can damage the ceramic element.? Popular with the stained glass crowd.? But I have to tell ya - you need to be very careful in not damaging any nearby SMT parts when using it.??

Think I'll celebrate by watching a 1972 Sci Fi movie entitled "Beware the Blob!"..

Thanks Mike, I will try tonight and report.

Thanks in advance,

Have you checked this yet?

Billy,

Have you downloaded, printed, punched three holes and put in binder yet? No? Well, don't! I did when I first ordered the radio and built it WRONG!

Do print the most recent build instructions when you actually get the kit. Then print the operating instructions when you finish and know it works.

This? is the most challenging an satisfying kit I ever built. It has the best instructions I have ever seen. These are pretty tall observations after experiencing Heathkits in the 50's and 70's and the Elecraft K2.

I have no idea how Hans keeps up? with his creations and remains accessible to all of? us but he does, somehow. This appears to be the most active forum anywhere on the internet. Welcome to the zoo!
