I recently purchased a few LCD displays from ebay, these were labelled up as Hitachi LM038 LCD Modules. There didn’t seem to be much information out there on the internet about how to use these, so I thought i’d put together a quick how to guide for anyone else who may have purcased one of these. In the example i’m using an Arduino (Atmel ATMega328) for speed and ease of use, however the process would be the same for any micro (PIC or AVR).

Just a quick update, lots of things happening at the moment to try and get the station ready in time for CQ WPX this weekend.
The Shack is looking really good, electrics are all in, room is painted, the cat5 needs to be terminated yet though.
The cable entry is finished in the ceiling, cable track is on the wall ready for Coax runs and you can see the wifi gear on the shelf, internet is provided using radio too, this is via a long distance 2.4Ghz link using Andrew 24dbi 2.4Ghz dishes.
Lots of homebrew engineering going on too, this is a nice home made guy point bearing made by Callum M0MCX
Here is some of our HEAVY engineering, more info on what this is soon 😉 (Yes that is a scaffolding joint)

Getting Plastered

Lots of progress this week.
The new shack is now plastered, we should have electrics by next weekend so we can finally start putting things back together ready for WPX SSB.
Lots of development work on new antenna systems this weekend too.
Here’s a few pics of the freshly plastered shack.

Antenna Switching

I’ve finally got the antenna switching finished tonight, nice new connectors fitted to the SixPak and the control box. We will finally have full sharing of antenna’s between all the stations now.
The new wifi router arrived today too, this is used for our long distance 2.4Ghz broadband link. Previously we have used a PC to share this around the network, a dedicated router is a much better solution. It’s a Buffalo WBR-G54.

VHF/UHF/Microwave Mounting

Made some progress at the weekend on the mounting brackets for the new VHF/UHF/Microwave stack, these are modified 24″ K brackets. Some of the brackets have been cut away to allow them to be mounted side on to the supporting brick post on the roof. Also got the drilling finished for the new connectors on the SixPak we will be using for antenna switching.
New Rotator (Create RC5-1) and rotator control cable arrived last week.

High Power Stub Filters Completed

Over the last couple of days i’ve managed to finish off the High Power Stub filter system. Last time we used this it was a bit of a lash up, so i’ve now completed the Band Pass Filter to HPF Junction Box system.
New connectors fitted to the SixPak’s, not sure why they don’t fit connectors normally, i suppose it keeps costs down.
Connectors fitted to the junction box.
Wiring of the junction box in progress
The completed junction box wiring
SixPak wiring completed
Testing of the system, you can see one of the BPF filter boxes below the junction box, this drives the SixPak relays.
All in all this should make for a much neater and easier installation of the stub filters.
