6m frequencies

Postby VK4DX » Sun Aug 12, 2007 9:19 am

I am new to 6m, in fact I'm yet to have my first QSO. Never had a radio with 6m before, now that I do I miss some sunspots. Oh well, you can't have it all at once. :roll:

One thing I'm a little curious about; I understand the 50.110 is a common DX calling QRG and 50.200 is the one for local traffic. But what frequency do you use for local CW QSOs, 50.200 as well ?

VK 50MHz Operating Restrictions
All VK amateurs have primary access to 52.0 - 54.0MHz.
However, the 50.0 - 52.0MHz band is allocated on a primary basis to the Broadcasting Service.
Amateur operation is permitted on the condition that no interference is caused to reception of Channel 0 television stations.

Restricted States

* VK1
* VK2 (except Jervis Bay area)
* VK3
* VK4

Operation is restricted to the sub-band 50.0 - 50.3MHz, using only CW (100W), SSB (100W) or FSK (30W).
Other than meeting local Council criteria there are no restrictions on antenna configuration/gain.

Main Stations
No operation is permitted within a 120km radial zone of main Channel 0 stations;

* DDQ-0 Mt Mowbullan (Darling Downs region - 170km NW of Brisbane)
QG53. 492kW EIRP, 46.171.806 MHz
(Parent station is WIN RTQ-7 located in Rockhampton)

* ABMN-0 Mt Ulandra (Wagga Wagga area - 350km SW of Sydney)
QF35. 328kW EIRP, 46.240.033 MHz
(Parent station is ABC ABN-2 located in Sydney)

Both these stations make ideal beacons for Eastern Australia!
Put these frequencies into your rig memories using CW mode. You'll hear (hopefully!) a ~600Hz beatnote.
Use them while they are still around!

Translator Stations
No operation is permitted within a 60km radial zone of translator stations with I/P or O/P freqencies on Ch0;

* NEN-0 Bald Hill (Tamworth area - 300km NNW Sydney)
QF58. 3.3kW EIRP 46.261.037 MHz

* ABN-0
Buckeridge Lookout, (Narooma area - 275km SSW Sydney)
QF53. 1.6kW EIRP 46.239.6 MHz
(Parent station is ABC ABN-2 located in Sydney)

* ABSN-0 Nanny Goat Hill, (Cooma area - 320km SSW Sydney)
QF43. 66W EIRP 46.239.63 MHz
(Parent station is ABC ABN-2 located in Sydney).

The five stations above are the only stations listed on the ACA database at 12/2/00.

Unrestricted States

* VK2 (Jervis Bay area only)
* VK5
* VK6
* VK7
* VK8
* and Australian Territories VK9 & VK0

are permitted 400 watts pep or 100 watts CW covering the full 50.0 - 54.0MHz.

Further to above, there are no restrictions on whether you can or shouldn't use CW on 50.200Mhz.
Put out a CQ, and see if you get a response! :wink:

The International DX window (50.100-50.150MHz) always attracts very strong, and opposing, points of view.
Some people are of the opinion that any DX on 6M is DX and can/should be worked within the DX window, whilst others (myself included) think that is simply poor form. Working across to VK6, ZL and FK via Sporadic E aint real DX, and occurs like clockwork every summer, so there is absolutely nothing special about it.

The best way that casual "DXers" and the serious DXers can co-exist on 6M is to respect each other.
Easy said, but rarely done.
If you want to have a QSO with VK/ZL/FK then do it above 50.150.
How hard is that?

The ultimate disrespect is when it takes several overs on 50.110 before brains wake up and you'll hear "... maybe we should think about getting off the call frequency...".
Gee, what a good idea.
It should be an automatic procedure to QSY above 50.150 after initial callsign exchange within 10-15 seconds, but rarely done.

Welcome to 6M! 8) :wink:

The fact is, whether it's good practice or not, everyone listens on 50.110 for a signal opening even just for E's. If you listen on 50.200 you are likely to hear nobody.

It's not such a big deal now at sunspot minima, but when F2 opens up more in the coming years then yes I agree it's a good idea to perhaps establish contact on 110 and then move up over 150 asap to keep clear of the weak signal chasers in the international DX window. Even consider 52 meg if MUF allows, that will give standard license holders an opportunity for contacts also.

Once things come good, how much CW activity is there on 50.11? Do many DX stations call on 50.11 and then move down once contact is established?

Not usually 110 for CW Grant. You'll hear it anywhere from 50 meg up when things hot up.

Mike

Welcome to 6m... now you realise that as you're a contestor and now planning activity on 6m there's no turning back - claiming sanity is no longer possibe :lol:

I know :shock:

Ha-ha, thanks Scott. I think I'll have to wait before getting my first 6m QSO into the log.

Working Newcastle in VK2 will be probably as exciting as you working Newcastle in the UK :-)

Cheers

Woo-hoo! Had my first QSO on 6m - VK5NY. And then couple of others, including ZL2AAA and then VK6JJ on CW.

Adam,
there are a couple of disagreements with your frequency list above and the published WIA band plan.
1. The published plan does not state CW only for the 50.080-50.100 segment, but is simply 'International DX window'.
2. The published plan states 'CW/SSB: DX or local for the segment 50.100-50.280, and not 50.300 as you have posted.
50.280 to 50.320 is reserved for beacons in the published plan, as in the 2008 callbook, and on the WIA website currently.

As your list is headed "WIA 6 Metre Bandplan", I assume you copied and pasted a listing published sometime, but apparently not the current one.

Six metres probably has the most complex band plan of all, but it shouldn't be too hard to get along IF PEOPLE READ IT AND FOLLOW IT. We seem to manage on most other bands!

Seems to me the hardest part is for an excited operator to decide what is DX or local in the heat of the moment. Maybe a bit more discussion on which is which might be beneficial all round.
Regards.

Yes, from the 2001 WIA Callbook.
Thanks Ken for pointing this out, and have amended list above.

Alternatively, operators can view the WIA Bandplan directly here:

Yep Adam, the Exclusive VK beacon band has entered the band plan. Understand Japan will stop killing whales if VK does some international negotiating before selecting freqs for beacons next time.

Adam

There must be an error in the band plan you provide in the link above. It states that 50.110 is the International Call freq and 50.200 is the Domestic Call freq. :lol:

Practically speaking, until the F layer heats up again, CW operators snuggle up as close to they can to 50.100
So 50.099 is the quasi-respected, semi-unofficial CW calling frequency. Make some noise - you will be heard during openings, even if I cannot come back to you (I'm in the no-fly zone around Mt. Mowbullan).

Adam's list of translators (in his band plan) is not the definitive one - check the regs before you blast away. For example, we have translators in Toowoomba and Murgon that have their *INPUT* on channel 0. Blast a few milliwatts into one of those, and you'd be servicing 50,000 households. :P

As "I" don't have a "band plan", what are you really referring to???
If something needs correcting, what is exactly is it?

Sorry, Adam, should have been more clear: the cut 'n paste job earlier in this thread, where you mentioned TV translators.
Wherever you took it from only mentions *outputs* on channel 0. *Inputs*, in my view, are far more important!
