InnovAntennas and MFJ Enterprises Announcement

InnovAntennas and Justin G0KSC have become well known in recent years for their innovative, quality antenna design.

They have just announced that a large part of their antenna range is to be made available through MFJ Enterprises, possibly with some modified models produced by MFJ designed to appeal to a market not currently met by InnovAntennas (this has been referred to elsewhere as the “mass-production area”).

The press release also indicates that new Yagi models will be released under the Hy-Gain and Cushcraft brands.

It is also understand that the former relationship between InnovAntennas and Force 12 has ceased.

MFJ / G0KSC Press release

MFJ Enterprises, 300 Industrial Park Rd, Starkville, MS 39759, USA and InnovAntennas Limited, Unit 1, Fitzherbert Spur, Farlington, Portsmouth, Hampshire PO6 1TT, United Kingdom

MFJ Enterprises a manufacturer of a broad range of products for the amateur radio industry specializing in station accessories, antennas and antenna tuner units and InnovAntennas Limited a designer and builder of modern computer optimized directional antenna systems, today announced a partnership which will increase the availability of InnovAntennas smaller antennas in addition to providing a new and up to date range of computer optimized directional antennas for Hy-Gain and Cushcraft, two of the legacy brands of MFJ Enterprises.

Justin Johnson G0KSC, owner of InnovAntennas Limited (a member of the International Ham Store Group) who is also a contributor to the ARRL Antenna Book 2016 provided the following statement.

‘’This is really exciting news for both companies. InnovAntennas have not been able to fully service the US market due to an inability to meet global demand. The MFJ facility in Starkville MS will be building some of the smaller antennas we produce under the InnovAntennas label and I have already visited the factory last year to established production methods using MFJ/Hy-Gain and Cushcraft tooling.’’

Justin continued by saying ‘’most of our popular models will be covered by MFJ, including the LFA (Loop Fed Array) Yagi and OWL (Optimized Wideband Low impedance). Additionally, new computer optimized and yet unreleased HF and VHF mono and multiband Yagis will be released through the Hy-Gain and Cushcraft brands, neither of which have released new Yagis in quite some time’’.

Justin Johnson G0KSC has become well-known for his innovative variants of the common Yagi which boast direct 50Ω feed points and low-noise patterns and feed arrangements. Dubbed the ‘urban antenna’ the LFA is well suited to city lots where noise prevents the hobby being as enjoyable as it once was. More recently, G0KSC has transitioned into HF multiband and monoband designs where he has embraced the compact ‘trap-less’ concept with the InnovAntennas CP-6 being an excellent example, providing 6 bands with a single feed in a package just 12’ by 28’.

It is expected that the first in this new line of antennas will be available by the spring of 2017 on a direct and distributor supply basis and it is advised that interest is place with MFJ Enterprises as soon as possible.

Moscow Aviation Institute MAI-75 Experiment, using the Kenwood
TM-D710 transceiver in the ISS Service Module.

MAI-75 activities have been scheduled on December 8, 1235-1800 UTC,
and December 9, 1240-1740 UTC. These times correspond to passes over
Moscow, Russia. ISS transmissions on 145.800 MHz FM use 5-kHz
deviation, and SSTV transmissions have used the PD120 and PD180

The ISS Fan Club website at can show when
the space station is within range of your station. On Windows PCs
the free application MMSSTV can decode the signal. On Apple iOS
devices, use the SSTV app available through iTunes.

DXplorer from Sotabeams – website now live

DXplorer™ is a unique web-based system providing facilities for on-air antenna system testing and comparison as well as real-time HF propagation analysis.

DXplorer™ is available for all radio amateurs to use but has been designed to be used with the new Sotabeams WSPRlite™ product..

WSPRlite (pronounced whisper-lite) is a low power transmitter designed to act as a standalone WSPR beacon on 30m (10 MHz) or 20m (14 MHz). Using a simple computer interface, you program the WSPRlite with your callsign, QTH locator. Once set up, the WSPRlite does not need the computer to operate. Just connect it to a USB power supply (e.g. mobile phone charger), press the “sync” button at the start of any even minute, and off it goes! WSPRlite will make regular transmissions that are automatically received by stations around the world.

WSPRlite™ users gain conditional access to additional features through DXplorer Premium™ which provides enhanced reporting features as well as a powerful real-time antenna system comparison feature.

DMR Repeater News for Northern Ireland

DMR Repeater for NorthWest Northern Ireland – GB7LY

An application has been submitted for the establishment of a digital voice DMR Repeater neat Londonderry in the NorthWest of Northenr Ireland, with the callsign GB7LY.

The Northern Ireland DMR repeaters will be based on Hytera RD-985 70cm repeater  equipment and the DMR+ standard. Although the DMR+ system may not be inter-connectable with the DMR-MARC system, in England there are a number of repeaters already on the DMR+ standard,  mostly in the English Midlands, and it will also be possible for D-Star users to connect D-Star using the DCS005F reflector

CEPT/ECC-EURAO: formal agreement signed

CEPT/ECC-EURAO: formal agreement signed


EURAO recently signed a Letter of Under­standing (LoU) with the Electronic Communications Committee (ECC) of the European Con­fe­ren­ce of Postal and Tele­com­munications Ad­mi­nis­tra­tions(CEPT).

Its aim is to cooperate in all Amateur Radio matters.

Most of us know CEPT by its recommendations T/R 61-01 and T/R 61-02. The first one allows radio amateur operation in other countries during short visits, usually up to three months. While the second one establishes the examination syllabus to obtain the Harmonised Amateur Radio Examination Certificate (HAREC), valid to get the license in a lot of different countries.

These seemingly simple recommendations involve considerable effort of coordination between national Administrations, a valuable task carried out by CEPT and its members.

With the signature of this agreement, EURAO wants to recognize the great work done but also to influence the upcoming recommendations and updates of existing ones, whith the objective of wider dissemination.

DMR Repeater News from Scotland

DMR Repeater for Dundee – GB7DD

GB7DD was the first DMR Digital Voice Repeater in Scotland and was  was first licensed on 4th March 2014 as a UHF Motorola MotoTRBO DMR Digital Voice Repeater.

GB7DD  owned by Martin Higgins MM0DUN but all licenced Radio Amateurs are welcome to use the repeater at any time subject to comliance with a few simple requests:-

  • ensure you disable GPS if you have that in your radio as it creates unnecessary data traffic on the network.
  • NO DIRECT CALLS are permitted.
  • Please also stick to the recognised Talk Groups and do not make up your own.

GB7DD operates on two digital time slots for licenced radio amateur use only;

  • Time Slot 1 is for World-Wide,  Europe,  UK-Wide and Local.  Direct Dial Talk Group 918 can be used by others to link into the GB7DD Talk Group 9 on Slot 1,
  • Time Slot 2 is for Local and TG8 Roaming.  GB7DD’s TG8 is part of the new Scottish TG8 Roaming bundle of repeaters which currently consists of GB7DD Dundee and GB7EE Edinburgh.

Please remember that repeaters are primarily for mobile users and you are asked not to hog the repeater or Talkgroup.  Please use the Talkgroup with the lowest number of external connections to reduce the number of repeaters being utilised by your QSO – for example don’t sit on UK-Wide if you are chatting to someone local, instead use TG9 Local.  Also, don’t sit on TG9 Local on Slot 1 for hours on end as you stop anyone else from making use of UK-Wide or World-Wide and stop Direct-Dial inwards from being accessible. Likewise sitting chatting for long periods on TG9 Local Slot 2 will stop anyone else from making use of the TG8 Dundee<->Edinburgh link.

GB7DD is located on the outskirts of Broughty Ferry on the A92 to the east of Dundee where the ground rises to the North and West.  A change of site may be considered in the future to increase coverage.
