Hans Summers kit: Ultimate 3 beacon

Today I unpacked this kit which I've had a couple of months. I have been waiting until I feel a bit better (less wobbly and clumsy) but now feel well enough to start the build.
Ultimate 3 beacon kit - received from Japan
I'll build the TX low pass filter for 10m first as this looks "do-able". The other parts may have to wait a few weeks. I want the kit building but want to do it when I am fit enough. The big issue will be boxing it. My brain bleed makes drilling cases a nightmare for me.

I was surprised to find no enclosed instructions. Guess one is meant to look on the net. Only unpacked the LPF module so far.  Being very careful.

Hi Roger,
all the construction instructions for the U3, as you quite rightly deduced, are to be found on a link on Hans web page. I suggest you read it right through before starting as there are some bits mentioned late into the construction that should be mentioned at the start. You have already started one, i.e build an LPF first so you can align the connectors on the main board. There is also a forum on Yahoo discussing problems and possible solutions people have come across.
Good luck with the build. It is one of the best kits I have ever built, despite some frustrating parts not supplied such as as the 2 pin connectors for RF connections etc, and a simple heatsink securing method for the PA devices. OK if your are a bit inventive I guess. 73 Ken G4APB

Thanks Ken. I intend to read the instructions carefully before turning on the soldering iron.

Hi Roger, also, Hans has updated the firmware to v3.04 now, affects WSPR, so you may want to upgrade your kit if you had it for some time.

Thanks Ken. Yes had the kit since Feb (I think) so I should update firmware before using it. I assume instructions on how to do this are on the net.

Hi Roger,
the re-programming instructions are on the net but for the U2 and a different uP. Hans did give me some pointers to upgrade mine but it looked a bit difficult so I took the easy way out and purchased an upgraded chip from his shop.

Roger,

there is a gentleman in the UK who is selling laser cut cases for the U3. I don't recall his callsign at the moment.

I would suggest joining the Yahoo group. Good discussions and quick answers. QRP Labs. I am having some trouble accessing Yahoo at the moment so I am unable to post a link.

cheers, Graham ve3gtc
