I take care of a pretty large EDACS system. There is a simulator built into my COM120B just for EDACS and LTR - even decodes pocsag paging.
This is never used in setting up the base station/repeaters. The procedure uses simple deviation and receiver tests. Same with subscriber units - most (but certainly not all) problems can be caught in conventional mode. On the repeater receiver a sniff point on the discriminator output allows basic receiver testing. This does not simulate DSTAR but gets to a go/no go point. Kind of like the first DPL - I had to buy an aftermarket board and wire it to my CE50 service monitor - would encode and if the light went out on receive - would decode as well. I doubt any manufacturer will make a test set for a low volume product because there are not enough folks wanting to pay for a DSTAR tester. Next problem - if the thing is broke - I am not gonna go probing around surface mount chips with my simpson and weller - better to box and ship. Anyhow that another 2 cents - might make payroll if this keeps up... 73, Steve NU5D Mike Morris WA6ILQ wrote: > > And one more point - and it's a major one.... > > You can get P25 test equipment. > > Show me one piece of test equipment - an IFR, an HP, a General Dynamics > (the folks that made some of Motorolas R-series of service monitors) > or any > other test equipment manufacturer that makes a dstar tester.
