Saia/Goosetown DMR Tier 3 (MOTOTRBO Capacity Max)

[ATCTech]

I'm confused. Are you saying you see exactly what I pasted? I'm receiving this on 454.6625 and that is CC=749.

It clearly shows 111 is 653, 101 is 145, 104 is 1939 and 117 is 1925.

My calculations yield the following:
Ch # 653 = 454.0625
Ch # 145 = 450.8875
Ch # 1939 = 462.100
Ch # 1925 = 462.0125
Ch # 749 = 454.6625

These are based on the database entry where Ch # 739 = 454.600

Yes I am seeing exactly what you are which is why I did not understand you saying 102 CC is 653 on your previous post.

Yes, that agrees with what I determined and it does not fit what the Motorola CapMax planning documents say is the normal "Fixed" bandplan but it seems to fit for this system so far.

Read it again. This is what I posted:

Site 102 is on 454.6875 and is reporting CC=653 for site 111

 

[ATCTech]

Ok, running each site seperately the CC channel designators don't match, you're right.

 

[GTR8000]

Before we get too lost in the numbers, can we please clarify Site 102? It's listed in the database as a control channel of 454.6625, however some of you in this thread are reporting the control channel as 454.6875.

Which is it for Site 102, .6625 or .6875?

Site ID​	Control CH ID​	Control MHz​
Site 101	145​	424.8875​
Site 102	749​	454.6625 or 454.6875
Site 103	739​	454.6​
Site 104	1939​	462.1​
Site 111	653​	454.0625​
Site 117	1925​	462.0125​

 

[GTR8000]

Hmm, CH ID 653 for 454.6875 doesn't make a whole lot of sense if 739 and 749 are in the 454.6xxx range. Are we sure that is correct? It seems that CH ID 653 should be closer to 454.0625 as @pro92b posted.

 

[ATCTech]

I wish I could. Using either 462.0125/1925 OR 462.1000/1939 in the TIII calculator program, the frequency for LSN 749 works out as 454.6625. However, using the chart you posted the frequency for site 111 shouldn't be LSN 653 as it's a higher frequency than site 102 LSN 749. The calculator shows LSN 753 as 454.6875. LSN 653, if this thing isn't lying to me, would be 454.0625. I'm seeing site 111 (in the neighbor list for site 102) as channel 653, hence I think site 111 is 454.0625/LSN 653. I can't receive it, so that's pure speculation. My previously posted frequency file was based on the DB here for the sites I can't receive, so site 111 using 653 is the right LSN but the wrong frequency in that post.

454.6625 is correct CC for Site L5-102

 

[GTR8000]

Regarding that T3 calculator, did anyone happen to read the part that says it doesn't work with Capacity Max? Has that changed since the initial release? Capacity Max is a form of T3, but it is not pure T3, so there may be some inconsistencies when using that calculator.

 

[ATCTech]

Ya, it's functionality is limited, hence the part about "if it isn't lying to me".

 

[pro92b]

Just FYI, I don't use the T3 calculator because at least in earlier releases it was not accurate. Maybe that's changed in later versions but I gave up on it long ago. My calculations are all done by hand.

454.6625 is correct CC for Site L5-102

I finally got a strong enough signal, as I've been "seeing" it for a bit now, just not good enough to decode. I'm pulling it in crystal clear on 454.6625 tonight (actually 454.6635, I'm sure my SDR is off, but strange enough, every other "known" frequency lines up just perfect, still )

After the discussion about Site 111 went off track yesterday about the CHID#s, I am back to my original question - can anyone hear Site 111, Arcade?

I can't hear SaiaNet Site 11 so I am probably out of range.

Nothing, not even a blip on the spectrum. I can't hear SaiaNet Site 11 normally, so I am probably out of range anyways.

 

[BTFire21]

Site 111 454.0625 in Arcade is not on the air today.

 

[Saint]

Just heard the tech's ask for a radio check / Buffalo Base TG=500101

 

[ak716]

Site 101 is back on the air, still 424.8875, CC 1. The first time its was initially reported/found at Sys ID 7, its 5, now consistent with the rest. No new neighbors
