HI All
Just to check so I blow anything up, I've got the cable from the Sunsdr going to the Expert 1K in the setting in the AMP would I need to set it up as a Kenwood TS480 Radio with just Band Data ??

Better to ask then have something go wrong with either the Radio or Amp.



Thanks in advance

Rob

You will not blow anything up, it simply will not work. And it will not at the moment because 'Kenwood' refers to a CAT protocol. The amp has to respond to the band data signals from the radio, therefore set it to that in the menu. I think you will find it under CAT>SET>YAESU>BAND DATA. That is from memory as I do not use this setting - someone might have better info.

Once again Erik many thanks I've got a Yaesu ft 2000 connected to my Expert Amp already so I will try the same settings as I have setup for that radio then as it also uses the band data.

Regards
Rob

Hi All
So what I have done is connect the Sunsdr2 -dx to the Expert 1K Amp with the cable supplied one end with AlLC cable i.e. sunsdr End, other end connected to the Expert Amp, next I've set the sunsdr software as the EXT_CTRL picture shows and also set the AMP for a Yaesu Radio using BAND DATA just the same as I have my FT2000 set up with the Second connection to the Expert AMP, So 2 radio's connected to the AMP with the same setting in the AMP, the FT2000 is working 100% with Band Data changing but the sunsdr can TX the AMP but NO band Data change?????

Any idea's could it be a problem with the cable ??? or something I've not set up correctly OP ERROR from me ??

Regards
Rob

What is 'AILC' cable? Is it a six-wire cable: 4 wires for BCD + PTT and GND? I presume so because PTT and GND are obviously correct since the the amp switches to TX. So I think we need to know the pin out at the SunSDR end. Was a pin-out diagram supplied? If so let us know it and of course you could also check with Roman. Sorry for more questions than answers but there needs to be more clarity about what you have in front of you and are working with. If pin-out unknown, work it out with a continuity tester.

I would suspect the cable over anything else. Provding it is properly seated in the ext-crl socket and RS-232 socket at the amp, there should be some reaction on changing bands even if it is not to the correct band. It's as if no signals are being received by the amp at the moment.

The Band Data cable was made up like this

The cable will have
BAND DATA, A B, C , D
GND
PTT

And an RCA /PHONO cable for ALC

Yes Rob, but on what pins? This is the critical part.It will work if properly wired but how do we know out here in the land of fog if it is or not?! We need to know, you need to know. Then it can be checked for correctness.

We can forget about ALC for the time being as that is irrelevant. X8 and GND are wired correctly. So the A B C D wires need verifying.

Just waiting for more information from Billy and Roman on pin out's from the cable and from the Sunsdr

If PENN is reading any of this if he's got his cable yet he might be able to say if he has his cable working so post if your reading this PENN

Hi Erik
I've had a message from Billy and this is what he said.
" The best solution I found was connecting them using the Yaesu-style band-data bits. You need to set the amplifier to Yaesu Band-Data. Pin layout: SUBD15 (SunSDR) DB15 (amplifier) 2 14 (Band-Data B) 7 6 (Band-Data A) 8 15 (Band-Data D) 12 7 (Band-Data C) 13 12 (PTT) 15 4 (GND) 14 via 510Ohm to 14,6,15,7 Additionaly connect a chinch cable to the ALC connector of the SunSDR ending in the same DB15 plug (Pin 5 ALC, Pin 4 GND) Then you need to set the band-data in the “Ext Ctrl” section of your ExpertSDR software to the correct values"

Hello Rob,

That is not the pin-out I was expecting to see on the SunSDR side. So, you will need to liaise with Roman. What I think will need to be done is a different set of values for the ext-crl table because the diagram you have is for pins 7, 2, 12 and 8 for ABCD.

I should stress this is what I have been told and I do not know from experience. But Roman should be able to work it out after you give him the pin-out as Billy has done it.

You can see why I said band data is so much more complicated than doing the radio-amp link by CAT. But nevertheless, must be achievable.

Hi Erik
I've sent all the info I've been given over to Roman so now waiting for a Reply with what ever updates he gives me Hopefully something will sorted and the radio will be work the Amp.

Roman if YOU can have a look at what ERIK has just posted and look at what I've posted from BILLY regarding the Band Data lead connection can you tell me if the BAND DATA picture from my first post on here is CORRECT as it looks like it's WRONG ?????

I've also E-Mailed you the same info but your last E-Mail I received this morning only has the PDF with the connections From the SunSDR Radio to the Expert AMP nothing that say's YES the picture with the Band Date info at the top of this post is correct with the cable pin 's on the cable I have???

HI All
So here is all the information supplied by Billy and Roman and hopefully Roman can check it and see if everything is correct

From Billy GM6DX cable info :-
" The best solution I found was connecting them using the Yaesu-style band-data bits. You need to set the amplifier to Yaesu Band-Data. Pin layout: SUBD15 (SunSDR) DB15 (amplifier) 2 14 (Band-Data B) 7 6 (Band-Data A) 8 15 (Band-Data D) 12 7 (Band-Data C) 13 12 (PTT) 15 4 (GND) 14 via 510Ohm to 14,6,15,7 Additionaly connect a chinch cable to the ALC connector of the SunSDR ending in the same DB15 plug (Pin 5 ALC, Pin 4 GND) Then you need to set the band-data in the “Ext Ctrl” section of your ExpertSDR software to the correct values"

Next will be the Info from ROMAN

Rob, I do not want to muddy the waters now - you'll rightly get furious. So go with Roman's solution in the final instance. But I have just done the calculation - took me 30 minutes and I'm not an expert so that's why you do not take this over Roman. I would say that Billy has wired the cable completely correctly. The BCD table is essentially correct too except that I calculated that 10m and 6m are transposed. But otherwise it should work. Which makes the cable not the problem.

Hi Erik
All I want to do is get the Radio working the the AMP, I've had another chat with Billy and he said
" Rob,
The only difference I can see is that in the cables I have made before there's a lead connecting all band data via 510 ohm resistor to pin 14.
Your cable doesn't have this but uses pin 14 as +v for the relay diode.
I suppose what you could do is disconnect that pin 14 at the SDR connection of the cable and then you will have the same as your cable regarding band data."

So All I need if help from anyone, You have helped loads so Thanks if Roman could post either here or by E-Mail and tell me and anyone else who might have the same problem how to get everything working together it would be brill, I won't then have cables and radio's all over the place hihi
