Great job Johnny boy..I wish I was retired!,
I like the big'un, looks very classy, if it's big it must be good.
When I was playing with the Fortec 2.4, I had no success with the Zinwell LNB and couldn't work out why. I ran a few noise figure & gain tests with the Zinwell compared against a Tit, Norsat & Chaparral. The NF was better than the Tit but not as good as the Norsat or Chaparral. However, there was something a bit strange that I put down to local interference. So the next step was to check the phase noise. Hardly needed, I could see the problem feet away. The LO appears to be injection locking an oscillation in the front end or vice versa. Curiously, the local oscillator can be stopped altogether with some input terminations. It does it on V & H.
The attached shows the IF output with a strong input signal and the 5150ish muck that comes out of the input guide. It's ******. Not surprising that no TV transponders would lock whilst I could still see something from the beacons.
It was DoA I guess they won't send a new one?I'll stick to mending my little indicator lights i think G.
Are you saying the Zins got you beat G ? .... surely not.
Cast your mind back a bit, what Cband lnbf was that little pcb circuit you built that switched LOF's of 5150 to 5750 by either 11v or 18v ?, was it on the Zinwell ?, do you think anything like that could be implemented on a Zinwell ?.

s-band,
There's nothing to be lost in asking AV-COMM for a replacement, after all, we did purchase 5 of them between us and it was a reasonable size order. They probably hold them as a stock item.
If you want to borrow mine for a couple of weeks for testing then you are very welcome, let me know and I will stick it in the post? I tested it briefly on a dish several weeks back and it was getting signals OK although I did not use it much. In the preliminary tests I did, it performed a little better than a Titanium, both directly in the C Band LNB holder and not using the polariser barrel.

Are these Zinwells available from anywhere other than Australia?
CJ,
They were listed on eBay from USA sellers last time I checked but the postage is often not cheap and you could get hit for taxes.

One of my jobs for today was to email Gary @ AV-Comm to see what we can do about it, will report back.

Here is the link to the eBay listing for the "Zinnies"

If anyone is interested in a spare, we could ask about a mini multi buy to see if it saves on postage?
If there is a multibuy going ahead, then for the price mentioned (+/-15% ) I would be interested in two of them.
