I finished my 20m QCX this morning and my 1 st QSO with it was with a couple of brothers who were operating portable in AZ, one of whom is building his own 30m QCX. I know Hans has sold a lot of these

Thanks for sharing your experiment with us Bob and good luck with your flight 73 Joe zl1rs@...> wrote:

Hi Bob Big congrats on the successful launch! I have added your info to a QRP Labs tracking page and started the tracking (the first part of the flight is missing but I can fill that in later).

:-) Cut down with side cutters to save weight Jack. The 3 boards in the pic weighed in at 5.8 grams after they were wrapped in insulation foam. 73, Bob ZL1RS

If a low power FT8 signal can not get through the higher power station activity,that makes is less than QRM ? I bet a 20mw Stanag 4285 continuous transmission would not be noticed let alone FT8. Lets

Poor thing...it looks like it was modified with a hand grenade! Still, as long as it works... Jack, W8TEE To: [email protected] Sent: Friday, December 8, 2017 4:40 PM Subject: [QRPLabs] ZL1RS

Sorry that should have been QRO abuse!

Also it would be interesting to see how a really low power FT8 signal gets through in spite of the QRP abuse. Not sure that WSPR popularity is declining though, could it be lack of sunspots! Roger

Exactly.? What's not to understand here?? I absolutely don't get the objection.? Aren't all those in the current U3S firmware "QSO modes" [sic] except WSPR? [See above re QSO capable modes never

No it's not.? QRM is using 1000W transmitters on a QRPp-designed mode and blowing every other nearby signal out into oblivion with their backblast.? Anyway, the number of QRP beacons are hardly

?I wonder if the OPA2134 would be a good replacement?? I haven't looked over the datasheets in detail.? I guess it also depends what you can get your hands on. 73, Michael KM4OLT

Thanks Eddie, ZS6BNE IF earphone jack shorts to ground = No Audio that is true BUT not affect the voltages on IC-10a, as cap C-51 provides isolationunless it is shorted ~ then the voltages would be

Hi Dee The gain of the I side is 3x higher than it should be. But this is somewhat cancelled out by the extra resistance (3.3K instead of 1K) in series to the I-Q balance trimmer pot. The I-Q balance

Hans, Regarding the swapping of R19 & R25 (error on silkcreen) what would be the effect of those two resistors being swapped? I think I allready know the answer but would like confirmation before I

Hi Tom, Good tip :-) 73,s Des (M0AYF)

Should have mentioned also that the current U3S firmware does already have HELL/JT65 and JT9...also QSO modes. I see no difference having FT8 for those that should like to experiment with

God kv?ll Daniel, Tack f?r din hj?lp, men jag vet inte n?gonting i encoder googla eller p? en kodarens spr?k. Om du har lite information om ?mnet kan jag f?rs?ka l?ra mig 73 och tack Joel

Hi group Order 6/10/2017 Shipped 27/11/2017 Received 8/12/2017 in France! Thanks Hans and all the team? 73 Qro Patrick? F6GWE

Sorry,too many QSO modes as it is and most operating,(not saying you guys) are using WAY too much power and not following the band plans. Each new QSO mode to me looks more like a bunch of seagulls

Tnx Hans ?
