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

Nice one Hans and all understood. Good thinking ! 73 de Andy

Hi Andy On key-up, the keying transistor Q1 is switched off, and the C1 capacitor is also supposed to mop up any RF leakage too. However some RF *still* can leak through to the antenna! It's many

Hi David That is why I liked the Trimble, integrated antenna, and also an auto switched SMA antenna socket for use with an external (waterproof antenna). Otherwise you could use a separate

I suppose there is only one way to find out. Plonk an LED On the output via a 2k2 and see what happens ;-) On my UP501 module I intended to have an LED connected all the time but it loaded it

Not quite sure I understand that one Hans. Do we Hell users have to apply for an NoV ? ;-) 73 de Andy

All Please note, U2 kits are still pending arrival of components here. So if you make an order which includes a U2, I hope it is Ok for you to wait for it all to be shipped together. 73 Hans G0UPL

Eddie, Now you've done it! Two showers and a train journey and Hans will have worked it out. 73 Keith, G6NHU

I second FTD,s remarks on the reyax UP501 modules... Faultless.. Plug n play ;-) de Dean G7EOB andyfoad@...> wrote:
