I don't think it's deliberate, malicious spam. maybe the IO Group message handler is trying to act on the contents of the dat attachment? I have seen it in other IO Groups, even some #tags in the mess

AFAIK, the differences in cell length are because cells may be unprotected or protected terminal construction which give rise to the different physical "standards" Alan

While *ANY* database contains incorrect reports it makes it's use as a definitive path indicator impossible. Likewise I was under the impression PSK did not show results for WSPR. Perhaps email the st

Alex, Have you contacted Hans at all, so he is aware of a buyer for a pre-built QCX20? As I understand it, you are able to request a specific band. If it not available ready constructed you may have t

Hi Alan, thanks' my post was just to make sure the Original Poster was waiting sufficient time for a complete TX cycle, like I have to..... Seems like later firmware does a NMEA parse for time on powe

I believe the current firmware operates the same way as the earlier revisions? Time & Locator fields are populated from the GPS at the end of the transmission sequence, therefore it normal for the U3S

I would be inclined to find out why it is unable to maintain the regulated 5v output? It could be a straight forward failure of the regulator, Alternatively it may be heavily loaded by one or more def

Do as Guido suggests, Saves having to stock a second inventory line..... never come across a mechanical encoder that couldn't be disassembled and the finger "spring" cut off or bent. Also take the opp

In days of olde.... (pre Astra? / SKY) analogue satellite receivers, a common sets own Intermediate Frequency was 70Mhz maybe freeview boxes use similar? Alan

As you have substituted the "chip" and DIP switch & the synth daughter board it doesn't leave much else..... I read the manual instructions as depressing the programming enter button as " do it positi

Chris, It's perhaps better if you start a fresh thread for your problems as it's a different, band you are utilising & different symptoms as your build initially gave the full 10W on 6Mtrs. A few othe

COLD..... I guess that is what prompted the experiment with super caps in the last flight, (rather than batteries?) Not sure if you flown those before? (And the U4B prototype, having the TCXO glued th

The kit was launched early 2015, little will be "new" discoveries..... Be Brave, Go for it.? If there is anything not covered in either of the manuals, or the forum you can always ask. Good luck! Alan

Hans, Thanks for the reply Good to hear about the power saving possibilities, It will be interesting to see if more balloons could fly with some sort of battery to perhaps operate at a reduced service

Great to see a new product. My U3 is currently located on a remote site & powered on a long extension lead, an enhancement would be to rebuild it using a solar panel and battery. One of the initial pr

Hi Denis, ?in the case of low TX power less is better..... If it really is minimal output then attention jumps to an easy one. You should see DC continuity from the Antenna socket back through the thr

Time out for a Reality check guys...... 1/.??? The suggestion was made by a no-body, and not Hans..... 2/.??? as its a landmark maybe he wants to keep it, if anyone's children are likely to become lic

Congratulations !! It must only a couple of months away, Perhaps keep No# 10,000 in the family or alternately auction it off for worthy cause? Alan

QRP Labs normally use 28 AWG....... Alan

AFAIK, QRP-Labs kits all use the same gauge wire, there are two hanks supplied in the case of the QCX. The main bags contain enough to wind T1 & L4 The LPF bag enough for those inductors. Alan
