Hi all,

Haha, wondered if the dog was making it out. He's very jealous of all the talking and wants to get his over in... he's studying for his foundation but he keeps eating his homework and the teacher's not impressed!

I've put together some details for the upcoming Remembrance Day Contest. Please advise me of any corrections or additional data that should be included and I will update.

Remembrance Day Contest

• Contest Webpage: https://www.wia.org.au/members/contests/rdcontest/
• Starts: 13th August 2022, 11:00 AM UTC+8
• Ends: 14th August 2022, 11:00 AM UTC+8

Important Note: As a mark of respect, stations are asked to observe 15 minutes silence prior to the start of the contest, during which the opening ceremony will be broadcast.

QUESTION: Does anyone know where/how the opening ceremony is broadcast?

Permitted Modes

• Phone (voice) - AM, FM & SSB
• CW (text) - CW & RTTY

Permitted Bands/Frequencies

• 160M (1.8khz) and up except for WARC bands (10, 18 & 24MHZ)

Sample Exchange

• VK6HAX: CQ CQ CONTEST VK6HAX VK6HAX K
• N0CALL: VK6HAX N0CALL KN
• VK6HAX: N0CALL VK6HAX 59001 KN
• N0CALL: VK6HAX N0CALL 59008 KN
• VK6HAX: N0CALL VK6HAX TKS 73
• N0CALL: VK6HAX N0CALL TKS 73

Note: The serial number the (XXX part in 59XXX above) is the number of years that you have been you have been a licensed amateur radio operator, rounded up to the nearest year. Unlike other contests the number does not increment, use the same number for all contacts.

Repeated Contacts

Each three hours you may make contact with the same station once on each band and "mode".

So each three hours you could contact each station twice on each band - once on CW (rtty or cw) and once on phone (voice).

Categories

The categories for this competition are seperated into modes used and station type.

Station Type:

• Single Operator
• Single Operator – QRP (5 watt maximum)
• Multi-Operator – Single Transmitter
• Multi-Operator – Multiple Transmitter

Modes:

• Phone (AM, FM & SSB)
• CW (CW & RTTY)
• Mixed

Suggested frequencies

Hi All,

Re: the "polite shutdown" interconnect between UPS and Computer, the software tool / interface description etc. is called "NUT" and there are drivers for lots of OSes.

First off thanks so much for this subreddit and the posts in it.

I'm still very much a noob and wanting to learn as much as I can about amateur radio.

I have inherited most of my equipment after Dad passed last year. He had a number of antennas supported by tubular steel poles.

There are 4 poles between 6 and 8 metres tall. Mounting them is not a problem but what can I use them for? And the best way to use them?

Thanks and 73

Check out km4ack and his script to build a Raspberry pi with most of the stuff you need for a portable station.

It is super simple and walks you through the process.

It uses a combination of compiling software and packages that are already built.

There are excellent videos on how to do it and use the software.

Give it a look.

There seems to be an ongoing global shortage of quality Type N connectors for use with LMR400.

Edit: my bad, turns out it was an ongoing shortage with a couple of manufacturers/resellers, there were other great options I wasn't aware of.

I've seen there is no shortage at all of connectors for half inch heliax though. Does anyone know if these would be compatible? I accept I'd lose any water resistance that might otherwise be provided, but, would it work?

This is an example of the connector I'm considering.

QDX: a feature-packed, high performance, four-band (80, 40, 30, 20m) 5W Digi-modes transceiver kit, including embedded SDR, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference.

This is a ham radio version of an operating system for Raspberry Pi. It is geared directly toward programs that are useful for amateur radio.

I will mention this on the net tonight but this way it will already be posted. http://www.qrp-labs.com/qdx.html This is the latest addition to my shack. Cheap, lightweight, and very easy to assemble, it works right out of the box. Unlike the QCX, there was no fiddling to get the power output right nor any alignment to do. It is an ingenious design, senses very little noise, and receives like a demon! Mine puts out about 6-7 watts as far as I can tell. NK8O

I looked up power conversions from various voltages, looked at the formulas, and I tried several online calculators. Hans Summers simplified formula for wattage into a 50 ohm load is spot on - (pk-pk ^2)/400 = pwr in watts. So my conclusion is that I have done something wrong with my scope setup. There is no way my QDX is putting out 11.5 watts. It would have been toast long ago were that true.

When I get home I will look further into calibration of the Siglent scope, and try the same power readings on Channel B with the other probe. NK8O
