Hi Webby, i just got back from droping the crab pots in for the nite and thanks to your above info I actually put the aerial on the VHF and had a listen in [smiley=2thumbsup.gif] [smiley=2thumbsup.gif]. cheers nq
Yes Zeeke but is that a pink ducky or a blue ducky
Anyway back to the real issue.
NQ, yes what one as to suffer with UHF (assume that's what to mean as CB VHF?) these days isn't what I'd like to see as the future of marine VHF, if 27mHz is down sized for any reason. UHF is an absolute shocker with the amount of useless garbage that goes on.
While those that are happy using 27mHz probably continue using 27mHz then possibly there might be some saviour in that. Really if 27 mHz was terminated tomorrow then really some would certainly require some education in "proper protocol" to move to VHF.
It's not that I've always been against 27mHz as once it was better than nothing for most users and even the first system that was introduced here was 27 mHz and back in 1976 is wasn't bad either, even if I say so my self . This setup had height, was landlined and with some special "modifications" to the transceiver it had quite a good range.
Today that antenna is still on that tower but there's no way I'm going back up there to remove it
Hi makka
you can increase output power (causes interferance with others, not legal) get a better ariel, maybe with gain (not dure if that option is available for marine)
cheers

Help!!!!!.
Recently put a new VHF into my boat. Now have both 27meg and VHF.
Last weekend when out wide from gold coast (20km) 27 meg worked fine (send and receive) VMR Southport. VHF also fine (send and receive) but trying to contact a couple of mates fishing up off deep tempest VHF could not pick up signal correctly but I could hear clicking on and off like squelching.
After talking to them on the mobile they said they could hear me on VHF and just audible on 27 MEG---
the aerial is on the rocket launcher and is 85 cm type.
not sure if this is the problem.
anyone with suggestions is welcome.-maybe I am expecting too much.
Were you trying to talk boat to boat direct freq or going through the repeater? If your mates could hear you ok and you were ok with VMR then that sort of points to the other radio maybe having a transmission problem.
The height/length of antenna has really more to do with transmission than reception but I'd go the longest antenna I could fit. That 85cm antenna isn't really affecting your reception (as such) but a longer one might improve your transmission but really your mate sounds like they have a problem.
20 km off the gold coast to deep tempest might be pushing the limits of range a bit. 90-100 km
vhf is normally line of sight operation.
your antenna is on the rocket launcher (good), maybe your mates is on the deck (bad)?
either way, i reacon you've found the limits with your setup.
get the antenna up as high as possible to increase the range
any more.
some vhf units have a high/low pwr switch also. like 1w/25w
wonder if your mate was transmitting using full power?
hi kerry, where are the marine vhf repeaters located??
Aido, over this distance the one to use would be Point Lookout North Stradbroke (VHF Ch 80), which just about sits in the middle and should be within reasonable range (~50km) especially being a repeater.
There's also Ch 21 on Cape Moreton, Ch 81 Mt Glorious and Ch 82 Yellowwood Hill Beenleigh.
From Southport through the Beenleigh repeater one would probably transmit to Moreton island but might be touchy trying to trigger the repeater from Cape Moreton as that's getting close to the limit.
Probably depends a little on the repeater location and height as some (not all) of our repeaters up this way are good for 40-50nm (80-90km).
. This setup had height, was landlined and with some special "modifications" to the transceiver it had quite a good range.
