I’ve just started playing out with a Morris side. On Saturday (St George’s Day), I was occasionally wedged between two melodeons, an accordion and a fiddle, and could barely hear my little Dixon alloy! Which high D whistle would be best for that kind of situation?
Every Dixon I’ve tried has been very quiet. If you’re looking for a loud inexpensive whistle then a Susato is probably more suitable.
Something like a susato?
I have one that I don’t play actually, it’s a non-tunable, ridiculously loud whistle. Plays nicely. PM me if interested would ask about £15 free postage.
Thanks, but… I have one Susato (low G) which I loathe. My least favourite whistle… Any other suggestions? Inexpensive is good.
Try a new direction and get a tabor pipe (Generation makes an inexpensive one) They’re traditional for Morris, quite piercing and it leaves you one hand free to smack those nasty box players (oops, looked at your avatar–never mind).
Best wishes.

Never heard a G but the D Susato is not a bad whistle for the price. Here’s a clip of Cormac Breatnach playing one… http://www.youtube.com/watch?v=0UWHg6BbfLU
Yes, buy the Susato. I’m not trying to be a smart-aleck either. The Susato high D is probably the best bang for the buck in a loud high D whistle. Do the O-ring tweak or learn to play it as it stands. They need to be played aggressively. You have to put a lot of air through them. They are good whistles, just somewhat mis-understood. 
Oh, and I really liked the Susato Kildare Low G I owned for several years.
At the other end of the cost spectrum is a Copeland, very good sound, very well made and very loud. You’d be heard in all circumstances. Between those would be the Water Weasel, if you can find one.

The clip I posted is actually a C whistle but It’ll give you an idea.
Goldie high Ds are pretty loud but a pretty penny too. I was out at Uffington White Horse for St. George’s Day and could be heard over 3 melodeons and 2 concertinas which is the only reason I mention it. Useless info, huh!. 
Other than the Susato how about a Syn tuneable D for £61. See the description at Big Whistle
The Parks from £40 is reasonably loud. I have the Every and play it at sessions where it cuts through all the melodeons. See Phil’s video, again at Big Whistle
HTH
Hoopy Mike might have a high D Susato to trade for your low G. 
I have a Garry Somers D for sale (see the instrument exchange forum). Wide bore aluminium, clear and flute like and a strong voice.
Just thought I’d drop a hint
My thoughts exactly! Actually I wondered about that even before I read this thread. Would that be ok with you, Phil? I meant to send you a thank you for the Susato - send me a PM with your snail mail address and I’ll post you a little something…
Perfectly all right by me Mike. I wondered if you would be hesitating, or else I would not have spoken.
PM sent.
There are few high D whistles that are as loud as the Chieftain Mezzo D - excellent for playing in a train station, airport tarmac, or football arena.

The down side is that these whistles can be difficult to control in the upper notes.
The Chieftain is very loud right enough, but unless you get an unusual good one it’s not going to be worth anything near what they go for. I used to have one and was embarrassed just to give it away. Very poor tuning and balance.
The Reyburn is a great loud D. Easy upper octave and great tone.
Thanks for all the replies! But try as you may, you can’t make me play another Susato. That YouTube vid of Cormac Breatnach does not sway me… it’s excellent playing, but the whistle still has that choked quality underneath it all, as if it really needs to clear its throat. It would probably improve a bit when drowned out by melodeons and accordions, but - no.
And just to show what a contrary person I am: I don’t like the feel of Chieftains either. At all. I’m sure they’re fine in the right hands, but I can’t get satisfaction from them.
I’d love a Copeland. It’s slightly beyond my credit limit right now, though…
Thanks for the info on the Syn and Parks whistles; never heard of them before. The Syn looks particularly promising. Can I hear a sample soundclip anywhere?
That sounds like the answer there!
The loudest high D which I’ve ever owned or heard is an old c1980 Susato I have. Huge bore, huge holes, huge sound. A real blaster- not “choked” in the least! It could be heard over a roomful of accordions.
In these situations the less-than-optimal tone and voicing don’t really matter- it’s really about being heard at all. You really have to blow out the high notes.
Matters to me. 
The high notes aren’t actually the problem; they carry above the squeezeboxes - it’s in the low passages that the Dixon goes under.
Anyanka,
I have a Syn D which I dont get on with. No reflection on the whistle, rather a reflection on me. I can confirm it is a very loud whistle and wonderfully made. I live close to the Hants / Surrey border, you are welcome to try it out if you are not far away ?
