Hi MikeG

Yeah I can see they have the SANWA listed on 27 & 40MHz - the one I have is on 29MHz. I'm guessing my one was imported direct from Japan not from some wholesaler in Hong Kong.

I guess I have an issue with 'retailers' selling gear that in all likelihood is not legal for use.

If somebody can produce information that says I'm wrong, good - bring it on.

 

[Mike G]

Gary, AMPBA says that we can use it, they are our "governing" body, good enough for me.

 

[GTR]

Hi MikeG

Are you able to show me where they say this because I couldn't find it in the rule book? Did someone from the AMPBA qive their opinion that it's legal? I would be disappointed if our governing body didn't know what their on about. <_<

This would not be the first time an administering body got it wrong. As I mentioned previously this has liability issues attached and we need to get official clarification.

They also have anew servo the 33005 metal gear standard size servo at Tower for $39 or so.  Anyone try them??

Don said he bought one and that it was garbage.

Garbage is putting it lightly. One smoked (& I mean smoked!) right on the set up table while setting trim adjustments. Another was dead out of the package. You also CANNOT run them with dry cells as the motor draws alot of juice (they went with a low cost motor trying to keep them cheap). I find that rather ironic as this servo was targeted at the car/truck guys to complete with the low cost HiTec servos & from what I've seen most of them seem to use 4 dry cells. <_<

As for radio I still prefer the Futaba 3PJS. Yeah I know you can't get them anymore, that's why some of you have seen me snatch up the last couple new ones that popped up for sale.

 

[Don Ferrette]

I see Futaba has a new synthesized radio for under $200. Looks interesting.

Hmmmm, the matching synthesized receivers are $115 each. Times 9 boats & one car .............OUCH!

Hi guys, this is the first time I have read all of the posts on this topic for radios and I find some very interesting points have been made regarding Australian frequencys. I've never given it any thought until now. There is nothing whatsoever in the AMPBA rule book about frequency values for Australia, in fact the only mention of frequencys in the rule book refers to radios being clearly marked and for storage purposes at an impound when used. (4.8 a,b and c)

I have read the artical posted here by GTR at http://www.aca.gov.au/aca_home/publication...info/models.htm and it clearly states that only 29 and 36 mhz is to be used in Australia. I see other posts in this topic speaking of 27 and 40 mhz being legal. Does the AMPBA recognize those frequencys as being legal for use by its members, whether your just fun running or at a sanctioned events ? I use 36 mhz myself but was intending on using 75 mhz as well this year so is 75 mhz as legal to use in Australia as 27 and 40 mhz is ?

I'd really like an answer for those ones from someone in the know at the AMPBA. I've seen some silly protests upheld at race meeting and speed events and I'd hate to see anyone have a record dis-allowed because they weren't using an approved frequency of all things. Please feel free to email me at [email protected] if you have any further info on this topic.

Cheers, Danny.

I guess my concern would be for organisations such as the AMPBA sanctioning the use of illegal frequencies during competition events.  There are some real liability issues here.

GTR,

I agree with what you are saying - please don't get me wrong here.

I've done some digging and discovered that the car racing organisations are also of the opinion that 40MHz is legal also. Not saying this is correct - just pointing it out.

I feel that any liability should be redirected to the importer - in my case that is an Australian company (they even put a sticker on the radio for "warranty" purposes.)

Danny,

75MHz is definately ILLEGAL here. I've raced at several different venues in the last year and never seen a 75MHz section on any radio board. I have seen a Certain AMPBA committee member using 75MHz in the past :unsure: great example being set there!

Tim.

 

[Danny Bull]

Hi Tim, As CD for many venues over the years I have seen 27, 40 and 75 mhz band used on many occasions and was not even aware that they were not to be used. Is it a frequency band that just isn't for boats or is illegal to use it at all, even when fun running or will I knock a 747 out of the sky if I turn it on ?

If the dept. of communications deems that only 29 and 36 mhz be used by radio controlled craft then how is 27 or 40 legal but not 75 ?

Could be a JR 756 PCM wheel set on 75 mhz with 3 FM receivers and 3 sets of crystals going cheap on Ebay soon...........lol and I am always looking for compatible receivers to suit my JR 756 that's on 36 mhz.

Cheers, Danny.

Hi TimD

I'm nt trying to get anyone wrong - or offside for that matter. The only concern I have is if we allow people to operate on illegal frequencies at sanctioned events we are liable to find our public liability insurance absolutely worthless. I'll admit I didn't even know that 27 & 40 weren't legal before checking. I knw that a lot of the car clubs allow the use of these frequencies - that still doesn't make it right. Allowing someone to take an illegal action will not cut it in front of the courts should anything go wrong.

As an examp0le you might remember an outrigger going full noiswe across our lake last year and launching into a park - I'm glad it didn't hit anyone - regarless of the frequency.

Generally speaking frequencies are allocated on a needs basis - it is probable that 40MHz is allocated for use other than ours. 27MHz definitely belongs to the CB radio frasternity. 75MHz who knows.

I have to say I agree with you about the importers bringing in gear that is not on legal frequencies. I would not be surpirised to find ACCC would have a problem with this. I know exactly what you mean as the importers re-sellers have a responsibility to the consumer.

I think the AMPBA might be scating on fairly thin ice if they allow people to run illegally. I'm reasonably sure the insurers would take a dim view of it. I acknowledge that the car guys do it but that is there problem to deal with if or when it turns to poo.

Don't most of these high end radios use modules? If so it should be relatively straight forward to change to legal frequencies - if this were to happen I think the importers should offer (as they had a big hand in it) replacement parts at very good prices. The other stuff should be good for the guys going to the US or Asia to compete, or for resale via Ebay etc

 

[Mike G]

Perhaps nobody noticed the link I posted before so I will repost it for all who missed. http://www.fastelectrics.com/hunter/ausfrequencies.htm They even say when it was approved by the AMPBA. Nationals in Dec 27, 29, 36, and 40 were all allowed.

Danny let me know if your selling your 75 stuff, I would like another 75 PCM receiver. One day I will travel to the US to race and it would be nice to be able to use my own radio.

 

[Danny Bull]

Thanks for your input guys, Mike the receivers I have are FM only not PCM. To avoid any hassles with using 75 mhz here in Australia, I reluctantly will be selling the JR 756 on 75 mhz with 3 FM receivers, 3 sets of crystals and charger. Any offers around the $240 USD mark plus shipping send to [email protected] or it goes on Ebay in the next week.

Cheers, Danny.

MikeG

I viewed the link you posted - AMPBA approved(?) these frequencies in 2000 - unless I missed something Gazettal and changes to the communications law in Feb 2002 are a few years more current and certainly overrule anything that the AMPBA might issue as guidelines.

<_<

Don,

I bought a GWS servo from Servo hut. Plugged it into my receiver, SNIFF SNIFF SNIFF "ME SMELL SMOKE" I unplugged the servo and thought well maybe it's wired reversed like an Airtronics. <_< Nope that wasn't it. I removed the 4 servo screws and saw inside the wires were bare and making contact. I e-mailed them and they said the "the warranty doesn't cover it"

and that must have been something I did. Yeah right, I opened a new servo spliced up the wires and ruined a $75 receiver for the F%#% of it!

:angry:

Crude, well back to Hi-tec servos...LOL

Here you go, off the ACA site, about half way down the page, Radio-Controlled Models. Updated 26 September 2003

http://www.aca.gov.au/radcomm/frequency_pl..._topics/srd.htm

I think the reason you could not find it before is because 27 is not regulated, I found a 1996 document opening it up for anybodies use! Pretty scarey really.

GTR,

Hey since I can't use my 75mhz radios in Australia I guess before I go over there (one day when I can afford R.T. tickets for 8) I'll have to buy a radio on the AUSsie e-bay and have it shipped to you! :lol:

Hi Mike

Thanks for the link - read that it says LIPD (would cover RC toys) - you'll notice the frequencies match the micro type racers etc. It also says RC have a specific license.

I can see your point about it being confusing but I would like to see a determination from ACA about it as it loosely defines LIPD to cover all sort of things.

Low Interference Potential Devices (LIPD)

The LIPD Class Licence authorises the operation of a wide range of lower power radiocommunications devices operating in various segments of the radiofrequency spectrum. The Class Licence sets out the conditions under which many types of short-range devices may operate. These conditions always cover frequency bands of operation and radiated power limits. Other conditions are applied as necessary.

These lower power transmitters for short-range communications do not require individual frequency

co-ordination for interference management purposes. Examples of equipment covered by the LIPD Class Licence include garage door openers, home detention monitoring equipment and personal alarms.

Other low power radiocommunications devices, such as radio controlled models, are authorised under separate Class Licences. These Class Licences include, the:

Radiocommunications Class Licence (Radio-controlled Models) 2002;

Radiocommunications Class Licence (Infrared Devices) 2002; and

Radiocommunications Class Licence (Spread Spectrum Devices) 2002.

I don't know it's very confusing :blink:
