Montacute CP

This afternoon, I packed up the new KN-Q7A Transceiver, the T1 Tuner, Squid Pole, 40M dipole, and a Battery and headed out to Montacute CP.


We drove to the end of the road, and walked into the Park along a section of the Heyson Trail for about 15 minutes up to near the top of the hill.

We set up just up the trail, near the top/right where it bends around near the crest of the hill.  Within a few minutes, I was sitting on the side of the track and calling on 40M.

Now, today was a special day as I was operating my new KN-Q7A Transceiver for the first time after a false start on Saturday, where I went out and found that The tuning was a little off!

I started calling and within a few minutes had my first contact in the log – and by all accounts, from everyone who answered I was doing pretty good from the approx 12 Watts I was transmitting.  Yes, that is my tuning “cheat sheet” – as the Transceiver only has a VXO.  Before heading out, we set up an SDR and plotted the frequencies and made a note of the dial readings for each 5khz step and then the maximum and minimum.   I only have 7072 to 7102 tuning range and it will do for the next few weeks until I build the DDS kit and mod it!

My “Portable Station” – we found a nice little plastic box that fits everything needed – radio, tuner, battery, antenna, patch cables and a logbook, just the 1 box and the squid pole makes going portable very lightweight.  For the astute, you will note, no internal speaker (wasting valuable space that will be used for other mods) instead, it is a speaker/mic which is quite reasonable.

Thanks to everyone who called and a bigger thanks to a few others who came down into my tuning range to respond to my call!

This afternoon, we worked the following VK’s –  5ZAR, 3PF, 3ANL, 3FPY/5, 5WG, 5FMID, 3AMB, 5PAS/p*, 5LY, 5FGMH, 5KGP, 5BB, 5CZ, 5FGRY/p*

There were a few new calls in the log and a few now familiar ones as well!

VK5PAS was portable operating from Mt George CP, and VK5FGRY was  also portable in Morialta CP, for 2 Park to Park contacts in the logs.

Lets face it, it is not just about playing Radio that makes it worthwhile getting out into the Parks because as we were packing up, the sun was just setting and it was quite spectacular!

With a sunset and view like this, why wouldn’t you want to be out there!

We were also rewarded with lots of birds and a couple of Kangaroo’s  crossing the track on our way back down.

Yep, if you look carefully, you will see that I took one of these sunset  Images and added it to my blog as the banner image.

… and then… Since Gary (VK5FGRY) was at Morialta CP, and literally only a 15 minute drive away, we dropped in there on the way home – why only do 1 park when you can do 2!

Gary was set up using his new 10M Pole from DX-wire and it is slightly larger on the top section than a standard squid pole making the whole 10M useable – certainly a good looking pole that is worthy of adding to the portable kit.  I borrowed Gary’s dipole and worked a couple more interesting stations.

VK5NIG was portable on Summit SE-013 – Mount Gawler and then VK3NBI/p and he was working from the Cape Ottway Lighthouse – getting everything ready for the Lighthouse Weekend in August.

For anyone looking for a nice lightweight radio, from the reports I had back today, that this one should be a real contender for a lightweight rig to put in a pack and get out there, certainly a lot easier than taking the IC-706 which we used for the first few activations, and in it’s current state, very battery-friendly on receive (only 40ma).

With today’s activation(s) I have now done 5 unique CP’s and probably now also logged enough as a hunter to qualify for a bronze hunter, not bad for a month!

Look forward to logging you from another park soon.

40M SSB Transceiver kit

A few days ago my KN-Q7A 40M SSB txcvr kit by crkits arrived.


When it turned up, I had to take a 2nd look – this thing is tiny – somehow I thought it was going to be bigger.

I have been putting it all together and at the moment the RX is finished and working, just the Output (Power Amp) Stage and physically putting it all together to go.

I spent a few hours over 2 evening and the assembly instructions are both logical and very good!  It is not a kit for the first time builder, but on the same token, with a few kits under your belt it would be an easy one to tackle.

Already, I am reasonably impressed with the receiver.  it has a nice, tight bandwidth –  350-2100hz, and about -45db at 2500hz.  Sensitivity-wise, I am only guessing, but based on my Vertical antenna and dipole, it is quite comparable to both the Icom 706 and the TS-2000 (with the TS 2000 set to 300hz/2200hz filter bandwidth).   I usually like to use 200/2400 on the filter so this receiver is very close.

Initially I am building it as-is and once it is all up and working I’ll then go and do a few mods to improve it in a couple of areas.

I went with the 7080-7100 VXO version and a quick check and It tunes from around 7077 – 7102, just perfect to cover 7090 and 7100 (and a little more as well).  Already, I have found that tuning is very touchy, but that will be solved when I modify it and add a DDS – yep I have the ILER DDS Kit  which will  replace the VXO – it will give me decent stability and be much easier to tune.


As this is a kit, it can be built to fit inside the case of the Transceiver, with the display in the top.

There are some nice suggestions over at David – VK3IL‘s blog for some mods that he has done and a bit of discussion relating to other possible mods as well.

The only other mods I am looking at is to add some audio processing before the Mixer – just a tad of compression to keep the average output power up,  probably looking at replacing or adding an extra audio stage  with some ALC and also to replace the toroid in the output transformer as per David’s suggestion.

Hopefully I’ll have it on air in a few days time, then start on all the mods.

CQ Parks

de AX5FO Calling CQ from Torrens Island Conservation Park.


Lets just step back a bit and see what it took to get here.  Last Monday, I gave Andy ‘5AKH a call and asked if could borrow his KX3 as I was planning to go over to Torrens Island CP  and Activate it on Anzac Day.  My request was countered with ” Can I borrow a kayak and I’ll bring my radio with me!”

With a final check of the weather reports and tides  saw us meet up at St Kilda boat ramp at around 08:00 (local time) where we sorted ourselves out and packed up to paddle the approx 2km over to Torrens Island Conservation Park.


We arrived a little after 9am right on low tide and dragged the Kayaks up above the expected tide level onto the beach.  We quickly assembled the station – a sand spike to hold the squid pole, up with the pole and we tied off the dipole to some mangroves.

At 23:47 UTC 24/04/2014 I made a CQ call on 7.100 and over the next 20 – 30 minutes we worked  11 stations.   We think that this was the first time this CP had been activated and when Paul, ‘5PAS came up,  we asked and he was fairly sure that it was the first as well.

Whilst I was working thru the calls, Andy was also busy, taking a few photos – you can see them on his Blog.

After the initial contacts, Andy came up and he also called CQ as AX5AKH.   Of course, given that the new day (UTC) had rolled over, he had a few repeat calls, but within the next 20 -30 minutes he logged 8 contacts in the log.

We then switched over and I made a CQ call under the Club Call of AX5ARG and we made 2 contacts.

About this time we had a visitor drop in on us – Matt, VK5ZM was out with his boys in the boat and he had gone via St Kilda and picked up Ray VK5RR and they joined us on Torrens Island.

Since he was there,  and we had both been calling, we told Matt to give it a go!  He also put out a call – and logged a further 7 stations in just 6 minutes!

With the tide showing signs of coming in, I made a final call and logged 3 more stations before we decided to pack up and head back to St Kilda.

A big thanks to everyone who answered our calls from this first activation of Torrens Island CP.  Given that the only access to the CP is via water, it takes a bit more planning and effort than the CP that you can drive right up to and I can hope that someone else will activate this CP again so I can log it as a hunter.

Much like the ANZAC’s 99 years ago, we arrived by boat and landed on the beach, but unlike all that time ago, we did not have anyone shooting at us.  Lest We Forget.

We came, we landed, we called CQ.

Apologies to anyone up front if you were calling as AX instead of VK, as we only logged the number’s and not the prefixes for most stations.  Please do let me know if you called as AX and I will adjust my logs.

Cannot promise to add a new park to the activated list next time, but hope to hear you from another NP or CP on 40M soon!

vk5 Parks Activations

On a whim, after working VK5ZAR whom was portable from a couple of Conservation Parks  on Friday the 18th of April, we (Bob – VK5FO and Ray – VK5RR) decided to go portable and activate a couple of Conservation Parks ourselves!

Not being totally prepared, in terms of a decent lightweight setup, we grabbed a (large and heavy) battery from our holiday shack, the IC706, A 9M squid pole, and a 40M dipole that I had made that morning.

20140418_130101We set up about 400M from the Road –  in the direction the sign is pointing.

For my Very First Activation it was White Dam Conservation Park about 15km up the Burra Road from Morgan.  We arrived, found a suitable site to set up the Inverted V,  Set the power to 30W, tuned to 7.100 and found it un-occupied and call CQ  at 05:45UTC (15:15 Local Time) and was rewarded with a reply from VK5PAS – A fitting First Contact!  Is it considered cheating to send an email out to the list at the same time you call CQ?

Over the next 1 1/4 hours, We logged 35 contacts from VK1, VK2, VK3, VK4, VK5 and VK7 stations!   2 noteworthy contacts in the log were from VK5ZAR who was at the time in Mintacowie CP, followed by a contact from VK5GY who was operating in Scott Creek CP, so 2 Park to Park contacts in my very first Activation.  With the Assistance Of Ray VK5RR doing the logging, I was able to keep calling and working everyone.

20140418_150503Setup – very Crude, but Effective, not even a chair!


The Calls were coming thick and fast and at times logging was a challenge.  When it quietened down, we pulled stumps, knowing that we provided another Park to 35 Hunters!

After we had something to eat, we headed out in the Evening to Activate Morgan Conservation Park as well.

20140418_121044Yep, we went up that little track to a clearing about 100M off the main road and set up.


When the Antenna was up, we found a clear frequency and started calling CQ on 7.085  At the same time we sent out a couple of SMS’s and an email to the list and we were rewarded within a minute or so with our first Contact.

First logged contact was at 09:55UTC (19:25 local) and the last one in the log was at 11:23UTC, when we pulled stumps again with a further 20 Contacts logged from VK2, VK3, VK4 and VK5.

20140418_191402Setting up in the Dark.

Since I listed my Contacts from the First, here are my Contacts for this park as well – VK5AKH, VK5MTM, VK5PAS, VK3ERW, VK5AV, VK5FYD, VK5VRB, VK3FONZ, VK3HRA, VK5MCB, VK5FLEN, VK5STU, VK3XP, VK3ETC, VK3MEG, VK2YKW, VK3BWZ, VK3MH, VK2UH, VK4HJB

Well, 2 parks, 1 day, had a blast!  Stay tuned for the next Activation as what is being planned is to activate a CP that we don’t think has yet been activated and is one that is a little bit difficult!
