The reception reports will have to wait until the updated firmware chip arrives so that I can get a 6 meter signal out of the U2... Else, I have a design that will fit. Also, waiting the filter

Done. That was very simple, I designed one some years ago and it is used on my Linear Mixer - Broadband Linear PA - VHF MEPT system, so I knocked up another. :-) . What is the penalty for proving

Very happy with my latest WSPR spot this morning with the new U2 on 20m 2013-06-18 07:44 KQ2RP 14.097100 -22 FN20 0.2 VK4GC QG62mj 15421km ~kQ2RP

Don't worry. Your Tesco's own brand coffee secret is safe with me ;-)) 73 de Andy (more a Carte Noir man myself)

It wasn't Nescafe! I could tell you what brand it was but then I would have to kill you ;)) Philip G4JVF

Mine too:) Colin M0XSD.

Was just looking at "flanged potting boxes" instead of Nescafe lids (copyright G4JVF) ;-) [SEARCH EBAY) These look like a reasonable way of affixing a protective top to a box, in which the GPS is

All If someone builds a 6m design, 7-element LPF which will fit on the kit PCB, I am happy to stock them in the shop. I think it would be good if someone proves it works first ;-) One free Ultimate2

I ran a fast 6 meter filter design from the AADE software and put the schematic and calculated plot in my Photos section KE7HR. This might be a starting point. Paul KE7HR

There is FREE filter design software at: http://aade.com/filter.htm It also includes a calculator to determine which toroid to use and the number of turns to complete the design. I usually take what

Fantastic. Mine is on order! Chris KQ2RP

My 30m MEPT "Multi-Mode Shield" kit from Hans G0UPL is on the air now from CM87. I haven't had any success with W4HBK yet but VE7IGH is reliable at night. I haven't measured or calibrated the output

Hee hee ! (See, I do observe!) Coffee jar lids once used here too. My first Top Band AM set up many years ago was a KW160 transmitter plus Lafayette rx. Antenna switch over between the two was

Well spotted Andy, tis indeed a coffee jar lid :) Good luck with your "picnic special" Philip G4JVF

Hello again Eddie This might be a bit more useful! http://www.ko4bb.com/Test_Equipment/Thunderbolt/PulseStretching/ And very simple to try. 73 Robert

Thanks Robert interesting stuff. I am sure Hans will crack it, if all else fails a special v2.01 GPS parameters with v2.02 RF will be the final solution, because the Trimble was fine on v2.01. 73

Dave, I have another U2 here which I am also planning to use as a "picnic portable" unit too ;-) My current thoughts are that I am going to build the second UP501 module that I have into the same

Hello Eddie Have a look at the circuit around the 1PPS for the PPS Piggie board here: https://www.tindie.com/products/gxti/pps-piggy/ Scroll down towards bottom of page. Maybe give some

Hi all, Happy to report that I built my U2 kit last week (aside from fully mounting the display in the box, it is complete). You can see my build

Hi Guys, Just in case anyone gets confused, there is no such thing as a Reyax UP501 GPS module! Reyax are simply one of several Far Eastern sellers on ebay. The GPS module being talked about was
