Building an MA-4472 speaker for MAXON SM-4000

Post by mbuhboot »

Hi,

I have recently bought a 2nd hand MAXON SM-4450 off eBay. The unit was listed without a PTT but the price was so ridicules that I couldn't resist buying it.

Looking for a PTT I realized there are limited places that sell the MA-4472 PTT - and in outragous prices (twice than what I paid for the radio :-) )

I found a schematic of the PTT unit (http://www.testequip.com.au/downloads/m ... ervice.pdf) and I was thinking of taking a low cost ICOM/YEASU compatible PTT which are solder for $5 (example http://www.dealextreme.com/details.dx/sku.14769) - any ideas on how to wire it?

Thanks in advance!

Moshe
