hodgei Posted November 15, 2007 Share Posted November 15, 2007 Could you upload some diagrams as this sounds like an interesting option for those of us who would like a cheap solution without all the complications of a comclone. Thanks. Link to comment Share on other sites More sharing options...
smalljoshua Posted March 4, 2008 Share Posted March 4, 2008 I found a great site for the Com Clone Stuff and I am about to embark on a 10 Box System using his schematics. Com Clone 2 Josh Link to comment Share on other sites More sharing options...
bruce Posted March 4, 2008 Share Posted March 4, 2008 I found a great site for the Com Clone Stuff and I am about to embark on a 10 Box System using his schematics.That'll be the one I mentioned (not explicitly - but it is the first google hit for "comclone") in the 5th post in this thread :) But keep us posted. It'll be interesting to find out how well these units work - there have been several discussions on them, but very few people have said "here's one I made earlier, and here's how it compares to the real thing..." And make sure you read cedd's comments in this thread Link to comment Share on other sites More sharing options...
pritch Posted March 5, 2008 Share Posted March 5, 2008 Anyone got any experience of these? http://www.altronics.com.au/index.asp?area=item&id=K5250 Looks interesting, and more of a complete solution than putting together a ComClone (which quickly got expensive just in terms of parts ). Got no idea how much they'd want in terms of postage from Australia, though... Link to comment Share on other sites More sharing options...
cedd Posted March 5, 2008 Share Posted March 5, 2008 Difficult site to navigate in order to find more info, but does look interesting. Would be particularly interested in seeing the pin-out protocal to see how it tied in with other systems. Doesn't use very standard terms but might be of use. More info required than the site will give! Link to comment Share on other sites More sharing options...
Don Allen Posted March 20, 2008 Share Posted March 20, 2008 These units were a project published by an Australian magazine, Silicon Chip, in June 1992. I have made a few of these and they work well and are compatible with Jands talkback units. Theye are housed in a snap together case that is fidly to modify for the pcb to fit, otherwise assembley is straight forward for someone that can solder. The receive audio gain is a bit high which means the cans are prone to feedback if you put them on a desk with the mic open. Link to comment Share on other sites More sharing options...
boatman Posted March 20, 2008 Share Posted March 20, 2008 The Silicon Chip archive only seems to go back to 2002. Do you have a link to the original article? Link to comment Share on other sites More sharing options...
ee61re Posted March 20, 2008 Share Posted March 20, 2008 I've contacted the vendor to ask how much the shipping would be to the UK for 6 packs and a PSU. Waiting for a response. Link to comment Share on other sites More sharing options...

Don't suppose you heard anything? I also dropped them a line, and I'm yet to hear anything. Link to comment Share on other sites More sharing options...
ee61re Posted March 28, 2008 Share Posted March 28, 2008 Nothing from them so far, but my email was playing up earlier this week. I'll try them again. Don't suppose you heard anything?

ee61re Posted April 5, 2008 Share Posted April 5, 2008 I finally got a reply from them on Friday. Delivery for 1 PSU and 6 packs will be $87 AUS, which is approx £45. That means I will still get change out of £300. Bargain! Rob Link to comment Share on other sites More sharing options...
ee61re Posted September 23, 2008 Share Posted September 23, 2008 Resurrecting this topic.... I placed an order for 1 x PSU and 6 x beltpacks yesterday with the Australian firm. The prices have changed slightly - its now $513 AUS total, plus shipping. I'm now waiting to hear confirmation of total cost and delivery time. I will post again when I have the kits in my grubby paws. All I then need to do is convince my pet solder monkey that he fancies building them all up for me. :-) Rob Link to comment Share on other sites More sharing options...

The receive audio gain is a bit high which means the cans are prone to feedback if you put them on a desk with the mic open. I got curious about these beltpacks and ordered the reprint from Silicon Chip magazine. They arrived this morning and a quick scan of the schematic shows that there is no hybrid circuit. This means there is no sidetone cancellation. It's no wonder they howl when the headset is taken off. Link to comment Share on other sites More sharing options...
ee61re Posted October 2, 2008 Share Posted October 2, 2008 Woohoo! £58 parcelfarce customs charge, and the kits will be with me tomorrow! Link to comment Share on other sites More sharing options...
