Thanks for taking the time to check out my QRZ profile page. I am fairly new to the world of Ham Radio, (only had my license since September 2015). In these few short months I have jumped from a Foundation licence holder, to an Intermediate licence holder. I would like to gain my Full licence as soon as possiblw. These past few months as a HAM radio operator have been fantastic and mind blowing, with two exams under my belt and a fully woring shack and three NOV's. I've also made many new friends along the way, and fully enjoy all aspects of the hobby from Project Building, HF to Digital Radio
I am now running three repeaters from my QTH in Mkt. Harborough, so feel free to use them if your passing by.
Simplex Gateway List
Node 43012 is connected full time to HUBnet, this is a UK based net with over 40+ full time nodes/repeaters. If you put out a call, you will be heard worldwide. Its a very friendly hub so you can have long QSO's, but please remeber to leave a 3 second gap between overs and please keep your overs to under 3 mins so not to timeout the repeaters. Click the logo above for more information.
Node 44194 is a 4 meter link and is mainly connected to the VermontNetwork. This is a US based net which is based Vermont County (east coast and picks up traffic from Pennsylvania. This link is a floating link, so can be connected to the WIN system or the WAN system or the HUBNet. Click the logo above for more information.
Node 43431 is connected to the WAN System. This is the US Wide Area Network which is based in Pennsylvania and covers the whole east coast from Maine to Florida. The same rules apply to this network as they do to all Allstar nets. 3 minute overs and a 3 second gap between each over.

Test Bench Area
Above photo is my shack workbench. When designing the shack I decided to devide it into two zones, one zone for radio use and the other as a workbench zone. I can play project building without getting solder and other things all over my radios. I'm building up a nice supply of compents that will be usefull in building projects, i.e resistors, transistors, relays, voltage regulators, switches, diodes and on and on. I am also trying to add tmore est equipment as funds become available.
Over the past few months, I have been bulding some QRP labs whisper kits plus other usefull things that will be usefull in the coming years. Some of my time has been put to good use building an MMDVM hotspot. The hotspot is working. I have added a 2.4in screen to the pi, this is connected with a USB to TTL converter.
The Icon IC-7100 is used for HF, 2 meter SSB and D-Star. This radio is connected to the MFJ 993B ATU, the ATU has two switch options. Option 1 is connected to the end fed 20meter long wire, Option 2 is connected to the SE-HF 360 Verticle Antenna. The VHF/UHF socket is connected to the 2 meter Halo for SSB contacts.
I have picked up the digital modes very quickly since passing my exam. I now write code-plugs for many hams worldwide. Below are some screen shots of my CPS programs that I use to write DMR code-plugs on. I write mine with talkgroups and not BM repeaters. The reason for this is simple, with BM's you have to faff around connecting and disconecting, with talkgroups its simple, just seclect the channel of your choice and press the PTT, simple. Talkgroups are user activated, so unless you press the PTT, your dont enter the room. Hope this makes sence?, if your looking for a ready to go TYT 380/390 worldwide codeplug, there is one in my link section below.
Below is my Arduino Uno and other bits that I use to load bootloaders and firmware onto the ATMEGA 328 blank chips ready for inserting onto the DVmega board which then builds up the bluestack hotspot..
I have had the pleasure of being given the opportunity to be a beta tester for the BlueDV Software by David PA7LIM . My feedback has been taken onboard and used to inprove the app. This blueDV app has improved digital radio to the point where its now posible to use your radios while mobile with minimal breakup and dropouts. Things are improving so fast, day-by-day in the world of digital radio, that its almost imposible to say what's round the next corner.
To build your own Bluestack hotspot, you will need the following parts which can be purchased from holland direct:
1 Bluestack (sigle band ) Board
2 Bluestack Micro Plus Board
3 Case (the plexibox is just butifully made)
Its childs play to create the bluestack. Just plug the blustack board onto the micro-plus board, fit the unit into the box and then screw the antenna on and then power up. The rest is controlled through the BlueDV app either windows, Linux or Android. Go into the settings and add your details and your away. It will work DMR, D-Star and Fusion.
The Icom ID-5100 is used for 2meter and 70cm use plus working my Allstar Node's
The Icon IC-2730E dual band transceiver is used for local 2m and 70cm repeaters. This is running through another Moonraker SQBM 100P Mk2 Duel band 2/70 vertical antenna which is mounted on the custom pole 1/2 wavelength apart from the D-Star antenna.
I've set up the 4 meter Allstar node using a Motorola GM350 radio with a Raspberry Pi 2 and a M0AQC sound fob. Im running this through a 4 meter Dipole for a time being, but I will be erecting a 70hz verticle antenna in the coming weeks, so keep checking back for updates.
Links To My Google Drive
Below are some usefull links to some of the latest software. These are files stored on my google drive and I will update the files as and when they become available. All programs have working key's so will run OK. All files are downloaded at your own risk, I will not be responsible for any corrution or damage to 3rd party equipment.

The photos below are my antenna farm mounted as high as I can get it at my QTH. The homebrew 446Mhz Dipole antenna is for Allstar node with the 2/70 supergain above that. The photo to the right is my 5.5 meter HF vericle mounted on a 12ft pole which is 6ft above ground. If you look closely you can see the HF long wire going through the picture.
My NOV Repeater Frequencys Details
UHF (43012) MB7IMH on 430.062mhz CTCSS 77hz
VHF(43431) MB7AMH on 145.287mhz CTCSS 103.5hz
Low Band (44194) MB7AMH 70.387mhz CTCSS 77hz
UK-Cluster (43405) with echolink connection 2E0XVX-L
You can connect to the UK-Cluster Node via a diect link 43405 or though Echolink on 2E0XVX-L, this HUB is also connected to K1GMM in Vermont US, so please leave a good 3-4 second gap between overs as you will timeout mine and also the other repeaters connected to ther group.
The above photos are my Allstar gateway repeaters. Above left is the repeater radio rack with the GM350 low band at the top,GM340 UHF in the middle and the GM340 VHF at the bottom. Right is the power supply with the pi's and sound fobs.
I also have two allstar micro- nodes which I use for portable use. These are contoled via a web page on the mobile phone or via DTMF keypad on the HT radio.
I also run sevral APRS Beacon 24/7 from the QTH - just serch for MB7IMH or MB7AMH on aprs.fi. I also run a Mobile APRS Beacon when driving - you can track me on aprs.fr by serching 2e0xvx-mobile
Now for a little background info on myself. I am 49 years young. I left uni in 1986, after gaining a degree in electrical engineering.I moved to the southeast of England where I worked for Nikon UK Ltd as a camera technition for some 14 years. My work entailed servicing cutomers camera equipment and dealing with all the UK main newspapers, also all of the MOD and SAS equipment. My "bread and butter" work was dealing with lady Diana's paparazzi, this was great as I knew everything about everything and everyone. After 14 years in the job, me and my family decided it was time to relocated back to our home town of Market Harborough as we are not getting any younger. This resulted in a complete change in career for me as I am now C+E HGV driver working for one of the Uk's biggest retailers. Since I'm now able to afford the finer things in life, I have got myself into a few hobbies, one of which is Ham Radio, so I hope to be making many new contacts and fiends along the way.
You can serch for 2E0XVX to find me on Facebook.
You can also serch for @micklawrence66 to find me on twitter.
I will say 73's for now and hope to catch you down the coax some time soon.
Below is a flag count of QSO made.
