AR Operators in New Zealand 1kw PEP From 30/11/2011

[VK4MIA]

For those that don't read the forum on QRZ.com

The New Zealand Government, Radio Spectrum Management section of MED that handles all radio licensing has increase the power for Amateur radio operators in New Zealand from 500 watts to 1kw PEP from 30 November 2011

NZART passed a remit earlier this year seeking an increase and the RSM website confirms this has now been approved

As from 30 November any one choosing to run 1kw can.

Don't forget its only a 3db increase and a good antenna can achieve more gain

Good to see the ZLs will have 1KW. I expect we also in VK should have that priviledge. Is the WIA still persuing the ACMA on this?

[VK4TIM]

I believe the WIA is pursuing an increase to 1 kW PEP, mode independant the same as ZL, but it is being held up by somebody in Canberra, whom I'm told is an Amateur. I'm also told he was due to retire several months ago.

The answer is yes. See: http://www.wia.org.au/newsevents/news/2 ... /index.php

Thanks Roger, appreciated.

I still fail to see why they are pursuing it on a "case by case basis".

[VK4MIA]

Be interesting to see if the power level increases will be across the board for all licence classes within VK and not just the Advanced.

Considering General Class in the US is on even keel with the Extra Class (power wise 1.5kw) but frequency restricted, 400w for the Standard Class here would be more than sufficient.

Hell, I'd be happy with 200 or 300, any increase is always welcomed

Let's not muck around.

Lobby for 1500 Watts PEP Output. Beating Kiwis might appeal to to ACMA bureaucrats..It appeals to me!

The argument for higher power was put in a previous thread.

The problem we face becasue of past thinking when the 1kw is allowed the conditiones will be difficult and stringent , wanting more wll make it more so
things will come into play like distance to neighbours and acerage for real power , of course going to only 1kw might mean some need to pull it back but imho a kw and a decent antenna at the alowable limit of 10 metres will do an admirable job . For that matter if it were not for Australia being so remote 400 would do the job but experience tells me sometimes more IS better , sometimes .

Hi all,

Can some please quote me the the ACMA actual wording with 400 Watts ???

There is a little twist to this - ZL orignally had 1500 Watt (or sligthy less) PEP (pX) rating with DC input to the finals.

We went backward to 500 Watts - and now up to 1 k/Watt - which is the same as what we had many years ago

Steve, ZL1TPH

[VK4KGW]

Well the regulations specify an amount of dc input hence the derivitive is 400 pep , which a very devious way of actually measuring it

16 Transmitter output power
(1) Subject to section 15, the licensee must not operate an amateur advanced
station, using a transmitter output power of more than 400 watts pX, if the
emission mode of the station includes:
(a) C3F; or
(b) J3E; or
(c) R3E.
(2) Subject to section 15, the licensee must not operate an amateur advanced
station, with an emission mode not mentioned in subsection (1), using a
transmitter output power of more than 120 watts pY.

it all comes back to the definitions vs common practice -

http://www.acma.gov.au/WEB/STANDARD..PC ... tter_Power

Peak Envelope Power 'pX' (s1.157) means the average power supplied to the antenna transmission line by a transmitter during one radiofrequency cycle at the crest of the modulation envelope taken under normal operating conditions.

Mean Power 'pY' (s1.158) means the average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long compared with the lowest frequency encountered in the modulation taken under normal operating conditions.

Carrier Power 'pZ' (s1.159) means the average power supplied to the antenna transmission line by a transmitter during one radio frequency cycle taken under the condition of no modulation.

So if the mean power has a time interval applied and we operate CW at say 25 wpm and assume with spacing and TX off times of say 200% then the maximum PEP allowed for CW is approximately 1000 watts key down - or did I work that out wrong ??

Hope you enjoy the info. I Did.

Thanks for that FXXX yes I have read the articles however the regulations based on a time constant on an unmodulated source with an untimed unrelated reference would give solicitors a field day...

Once again, don't hold your breath.
