End of European Roaming

End of European Roaming

On the 6th of April the European Commission released a press release announcing that from the 15th of June all roaming costs in the European Union will disappear.
In the press release the following statement can be read:

“As of 15 June 2017, you will be able to use your mobile device when travelling in the EU, paying the same prices as at home, i.e. to roam like at home, subject to operators’ fair use policies. For instance, if you pay for a monthly package of minutes, SMS and data in your country, any voice call, SMS and data session you make while travelling abroad in the EU will be deducted from that volume as if you were at home, with no extra charges. This means the end of roaming charges as travellers have experienced them so far.”

Rumors were saying that the

ON0MON – QRT 31 Dec 2016

ON0MON – QRT 31 Dec 2016

Due to some personal issues, I will no longer run and maintain the ON0MON Repeater. I will decommission the equipment on the 31st of December 2016 and probably return the call sign to the IBPT/BIPT on the same date.
The repeater is for sale, in case someone wants to buy it, and it is based on:

  • Motorola RM900,
  • Tono 70W UHF Power Amplifier,
  • Duplexer cavity tuned for the actual frequencies
  • D-Star DVRPTR V2 (Ethernet + USB support, works standalone).

Solar PowerBank for FT-817ND

Solar PowerBank for FT-817ND

Weekend project: Solar rechargeable Power Bank for the FT-817ND.

I had two spare batteries, a plastic box IP65, a 20W solar panel with its controller, a tripod and some wires lying around my garage and I’ve decided to build something with it. I placed the two batteries in the box and wired using a 1.5mm cable, then installed the solar panel controller outside and wired the batteries to it. I’ve used a 3 X 12V car plugs as output considering that the solar panel controller has two USB ports embedded so I will have both 12V and 5V ready available anytime.

For the step two I started to build the support for the

FT-817ND

FT-817ND

I went to Friedrichshafen last June and my friend Jean (IZ7SIA) started busting my chops by eulogize how wonderful is the Yaesu FT-817ND, how portable is the FT-817ND, how nice is the FT-817ND, and blah blah blah.
I was not really interested in a portable HF device because I’m already working on the M0NKA’s project, the pain-in-the-ass-to-build QRP radio mcHF therefore I didn’t want to spend money on another portable rig; then when you cross Jean with Max (IW0GXY) and both are with you in front of Marco’s stand (IW2CSY) then you are forced to take out your wallet and swipe your credit card… so now I’m a owner of a FT-817ND.

MMDVM Single Face Modem

MMDVM Single Face Modem

My old and very good friend Enzo (Vincenzo – IU7ACP) has just build a single face MMDVM modem for testing. I will receive the board in the next few days and start some tests with some Motorola and Kenwood radio to see how it works. There are no plans for a mass production at the moment. I will deal with Enzo to have it Open Source with all the diagrams published for everybody.

Update 18 Mar 2017: Unfortunately the device didn’t work and I have abandoned the project.

mcHF 0.1-30Mhz QRP RTX

mcHF 0.1-30Mhz QRP RTX

My son (ON3II) and I just started building the mcHF SDR Transceiver project form m0nka (http://www.m0nka.co.uk).

It is an interesting project and honestly quite difficult to complete even using the pre-populated boards.
There are so tiny components such as the coils and some SMD integrated circuit which are requiring a proper SMD soldering station. A reworking station might do the job but the risk of de-soldering another component installed nearby is very high.

The radio itself costs 259 GBP plus 10 GBP for the shipping in Europe which converts to 350 Euro circa, not a bargain but still a funny project. The kit doesn’t include the box neither the Power Amplifier final Mosfet (RD16HHF1); the box is available from Artur SP3OSJ (http://www.sp3osj.pl) for 50.50 Euro shipping included in Europe. For the Power Amplifier MosFet, you can find them almost everywhere at a price ranging from 1.50 Euro to 25 Euro per piece. I bought mine from FunkAmateur in Germany (http://www.box73.de) for 6.70 Euro each, so 13,40 for the pair plus shipping.

I’ll post a review as soon as the kit is completed.
