Does anyone know of an alternative to Ham radio Deluxe.
I have an old version that wont control an IC-970 but can see DX labs have a version that listed IC-970 but cant for the life of me see how to down load the program. Any one got a link to this program please.

SEQ Microwave Activity Day - 24th Feb 2019 |

Gentlemen,
On the Sunday the 24th of February, the BVHFG will be conducting activity on the microwave bands and as many bands as possible from 1296 MHz & above, activating many portable locations (weather permitting) from 12:00 noon.
So try going to a local lookout or suburban hill top and give it a go.
This event on the Sunday 24th is meant to include the established tradition of "23 on 23" which would otherwise have been held the evening before. Liaison between stations could be on the VK4RBN repeater (now with DCS access), or 146.550 MHz FM simplex, or 439.000 MHz FM simplex.
It would be really great that numbers of South-East Queensland and Northern NSW radio amateurs "seize the day" and go out and have some good clean radio fun on the 24th of this month!
Some members are planning to go to locations like Kamuran Lookout to the South, Toowoomba to the West, Stradbroke Island to the East & Howells Knob to the North, just to start with, but not limited to.
So grab that box under the desk, brush off the cobwebs, poke the antenna up and add some power and try that PTT button out, the airwaves are going to be active.
So please share this email around with other Keen amateurs who may have the microwave gear and those who are thinking about it, and have a fun weekend with many contacts on the microwave bands.
Also meanwhile check out these :

New Campaign Exploiting Linux Servers to Insert Backdoor "SpeakUp" Trojan |

New Campaign Exploiting Linux Servers to Insert Backdoor "SpeakUp" Trojan
A new backdoor Linux-based operating system Trojan dubbed "SpeakUp" is on the loose, although so far it does not appear to have propagated to North America or Europe. Research team Check Point Research recently reported the discovery and said SpeakUp exploits known vulnerabilities in six separate Linux distributions and is able to evade all security vendors.
Some radio amateurs use various forms of Linux, including the popular Ubuntu software, which includes ham radio apps.
"The attack is gaining momentum and targeting servers in East Asia and Latin America, including AWS [Amazon Web Services]-hosted machines," the Check Point Research article said.
"SpeakUp acts to propagate internally within the infected subnet, and beyond to new IP ranges, exploiting remote code execution vulnerabilities. In addition, SpeakUp presented ability to infect Mac devices with the undetected backdoor."

Volunteer Examiners testing for USA Licences & Wyong Field Day |

From: WIA NATIONAL NEWS FOR WEEK COMMENCING Feb 17 2019
Julian VK2YJS dropped us a note through the week to say, and I quote " There are a range of reasons to obtain a US Amateur Licence, including for travel, as while there are reciprocal arrangements, these do not cater to all users or needs; the challenge, or for the CV; and to yourself become a Volunteer Examiner in the US system.
I, Julian VK2YJS and AG6LE advise that the Oz VE group will be running exams to obtain such a licence at the Wyong Field Day February 24.
The fee is US$15, or around A$22. This allows one attempt at each of the three papers, Technician, General, and Extra. Relevant regulations are integrated into each paper, and all must be passed to get the Extra.
A range of training resources are available including:- hamtestonline.com site.
More information can be found on the website:- veexams.com "
Are you going to the Wyong FD and are prepared to do the tests ??
You have about 1 week to get ready !

ExpressPCB series of PCB layout software |
Posted by: VK4ADC - 09-02-2019, 09:06 AM - Forum: Off Topic!
- No Replies

I have been using ExpressPCB for laying out my PCBs for some years but today (finally) got around to trying the ExpressPCBPlus free software : https://www.expresspcb.com/
I imported all of my custom components, opened my old ExpressPCB layout files (.PCB) all without issues. When I selected to print a layout, it gave me several print options including the photo transfer method that I use with pre-sensitised positive resist PCB that I buy from RS Components, direct to PCB (ie mirrored) if your printer will support that, etc..
The layout can quickly be flipped to show the other side of the board where previously it was a matter of hiding the top and/or silkscreen layers to see what was below.
It does NOT do auto-routing but does interact with a netlist from a ExpressSCH schematic file.
In all, ExpressPCBPlus looks like a really good candidate for amateurs to use for their PCB-based projects.
The PCB123 (same web page link) may look good but is probably a little harder to get used to. It doesn't seem to open the ExpressPCB (or Plus) layout files and has different library options - which may be good for some users but not when you have 130-odd custom parts layouts that you might have to re-create.
There are 3 versions of the software available from the website at https://www.expresspcb.com/ , all free to download and use. The 'catch' is when you want to order PCBs - the cost for 1-off is high - but if you do your own print / expose / etch processes at home then it is a great free software tool.

John Moyle Memorial Field Day - 16/17 March 2019 |

This event is only just a little over a month away so start making your plans...
-----------------------------------------------------------------------------------------------------------
Aim Of The Contest
The aim is to encourage and provide familiarisation with portable and field operation, and provide training for emergency situations. The rules are therefore specifically designed and focussed to encourage field operations.
Contest History
The contest is run each year in memory of the late John Moyle who was a long term editor of the Wireless Weekly, (later Radio & Hobbies - later Radio Television & Hobbies) from 1947 until his untimely death in 1960.
He served in the RAAF with distinction and was responsible for a number of innovative solutions to keeping radio and radar equipment working under difficult wartime and working conditions.
The WIA decided that a suitable long term memorial to John Moyle would be a Field Day with a focus on portable or field operation. The contest has been conducted annually ever since.
The rules of the contest have gradually changed over time and are still revised regularly.
The contest is still for portable or field operators, though Home stations can of course take part using a different scoring system.
Though Multiple Operators and club stations are actively encouraged to take part in the contest they are not competing against the single operator stations and in effect there are two separate contests run at the same time. Hence single operator stations take part in their own contest against other single operators.
Upcoming Contest Date & Time
The next Field Day will be held over the weekend of the 16th-17th March 2019 and will run from UTC 0100 on the Saturday to 0059 on the Sunday.
-----------------------------------------------------------------------------------------------------------
Full details : http://www.wia.org.au/members/contests/johnmoyle/
A PDF of the rules for 2019 is not (yet) on the WIA web site but will undoubtedly be similar to the 2018 rules : http://www.wia.org.au/members/contests/j...Y_2018.pdf

Signal on 144.2Mhz from FM broadcaster |

We did some test at Mt Cotton Radio site today to see if it was suitable for the John Moyle weekend coming up.
We want to operate HF 6 2 70 23 and 13cm there is a whopping signal with modulation coming from the local FM station on 100.3 at about 100 metres away its all over the band we moved along the hill 500 metres and it was better but shouldn't they be down 80db at 40 MHz away. I think its only a 200 watt Tx. Has anyone had this problem ? Been out portable and never had anything this bad.
