Re: [Repeater-Builder] SQ-1000 vs RLC-MOT Squelch

[Kevin Custer]

Hi, The Link Comm unit is much smaller and much better suited for installation in other than Micor equipment.  Of course, this 'convenience' comes at a price, but if you aren't cramped for space there is no advantage of the Link Comm unit since it is solely based on the Micor Squelch Chip.  The Link Comm product is, in my opinion, the best choice for adding a quality carrier squelch to any radio lacking a good one, at this time.  It is a very popular upgrade in our Mastr II, MVP and Mitrek mobile conversions. I have used every replica squelch board available today, including the SQ-1000.  The SQ-1000 is the better choice of all of the replica boards, but like all of them, it's digital and it operates like it's digital.  These replica boards use processors that aren't fast enough, in my opinion, for analogue like squelch action.  Another problem is some of these boards suffer from insufficient high pass filtering and voice talk off, along with other issues, can really become a problem.  The SQ-1000 has sufficient HP filtering, but I just don't care for a digitally derived carrier squelch. Scott Zimmerman and I have been working on an analogue replica of the Micor Squelch for some time (several years).  Since the Micor Squelch chip is still available we haven't spent any serious time perfecting it.  Some day the Micor Squelch chip will be hard to come by, and we'll dig out our version of this circuit, perfect it, and turn it into a product.

I'm looking for the dual squelch action of the Micor squelch circuit. At this point in the game, there is no substitute or equivalent to the Micor squelch chip, in my opinion. The RLC-MOT actually uses the Motorola Micor chip, so it would be the one of choice between your two suggestions... Kevin Custer Yahoo!
