Re: Can I operate two radios over CI-V an same CI-V HUB.

Dave AA6YQ
 

Could be debated that even Icom does not always follow properly there own standards...

+ the PW-1 is the only example I know of where Icom violates the CI-V bus specification. It has no collision detection capability whatsoever. See Larry K8UT's analysis here:

http://www.k8ut.com/wpfb-file/riding-the-ci-v-bus-by-k8ut-pdf/


And you have to be careful about OEM devices... devices like Band decoders are not always passive, some like the Band Decoder II actually can be active polling the radio, this can definitively cause a collision with other radio, devices or applications. A device like a band decoder SHOULD be passive sniffing the data on the bus if another device or application is already using the CI-V bus that needs priority...

+ I can understand why the ability to poll the radio is provided, as it may be needed in some topologies; but there must be a way to disable the polling when the only thing it's doing is creating collisions.

I have been working on a very flexible routing approach for many months, debugging at this time latency issues...but this approach does help some of these issues.

+ I've found it sufficient to provide a private CI-V bus for the PW-1, thereby eliminating any possibility of collisions. All other valid topologies are handled by collision detection and retransmission as described in the CI-V bus spec.

Dave, AA6YQ


Re: Can I operate two radios over CI-V an same CI-V HUB.

VE2DX
 

I fully agree, Dave!

Could be debated that even Icom does not always follow properly there own standards...

And it is very difficult to know if all application and hardware design (firmware) apply or not the ICOM standards properly...

The issue of the Applications ALWAYS using E0... This is wrong, if multiple radios are being accessed by an application on a single CI-V bus a different controller address should be assigned.

And I agree also that putting multiple radios (that do not need to be on the bus) on the same bus bring multiple issues of collision.

And you have to be careful about OEM devices... devices like Band decoders are not always passive, some like the Band Decoder II actually can be active polling the radio, this can definitively cause a collision with other radio, devices or applications.  A device like a band decoder SHOULD be passive sniffing the data on the bus if another device or application is already using the CI-V bus that needs priority...

I have been working on a very flexible routing approach for many months, debugging at this time latency issues...but this approach does help some of these issues.

Depending on your needs you should ALWAYS keep in mind the possibilities of collisions on your CI-V bus, and look at the need to split your station into multiple CI-V Bus set up to prevent this.

Re: Can I operate two radios over CI-V an same CI-V HUB.

Dave AA6YQ
 

The CI-V protocol is defined to support interactions among multiple nodes. With more than two nodes communicating, there will likely be collisions. The protocol defines how collisions should be detected and resolved, but not all hardware devices conform to the protocol; the PW-1 amplifier, for example, is notoriously non-compliant. Furthermore, not all computer-hosted transceiver control applications conform to the protocol's collision-handling requirements.

Can I operate two radios over CI-V an same CI-V HUB.

VE2DX
 

Well, the answer is; yes and no! It depends...

One a unique hub like CT-17 or the VE2DX CT17B series, you CAN run more than one radio linked to the same computer...

But...

Yes, there is a BUT... :P

Your CI-V is an addressable protocol where each radio has a unique address AND (this is a BG ONE!!!) each computer output or application MUST also have a UNIQUE address...

And this is where we run into a problem, since on an ICOM CT17, VE2DX CT-17B-5, CT17B-6, or CT17B-6BT all the devices are on the same hub bus then if you start two sessions of HRD for example talking to two radios even via separate ports (USB and Bluetooth for example) then HRD is always using E0 as the computer.

Thus... when the 7300 responds to the HRD source1 with 28.074.00 for example, it is possible (likely!) that you will see that same freq pop up in HRD Source2 (the 9700) and then flip back and vice versa...

To fix this the source program would have to use a unique Address like E0, E1, E2, etc... and this would solve the problem since E0 would be use by the 7300 to respond and E1 would be used by the 9700.

this is RAREly available in most applications.

Solution;

Simple either install two separate hubs.

or use a VE2DX CT17B-10, this is a 10 port hub where by removing a simple jumper you can split the hub into two 5 port hubs...

And yes the CT-17B-11USB, CT17B-11BT, CT17-12USB and CT17B-12BT and coming back... I am working on new versions of these babies that will blow your pants off...

A lot more new stuff coming out soon, We finalized our IMK2-JR 7610, 7850, 7851 and 705 8 memory keyers with external M1 and M8 footswitch connectors, working on releasing next month the IMK3J3, Larger and added features IMK3 and dual radio IMK3uP, all 4 memory keyers with TONES of features...

Re: IC-705 antenna switch from band data

Ken N2VIP
 

As a follow-up to my previous note, since I missed that you wanted separate HF, VHF, and UHF antennas, you would need a single triplexer, like this:


To gave you automatic selection of an HF/6m line, a 2m line, and a 70cm line.

Hi Richard

I have been looking at the CT-17-BT6 to see if I can get it switch relays per band using CI-V data.

I want to run my 705 remotely via some new Mac software that DL2YMR has released. When I am on a HF band I would like to have a HF antenna connected and when changing to VHF a specific VHF antenna connected via a relay and the same for UHF.

Do you have something that will do this easily...I see you are working on a router that may also be able to do this.
On each coax after the relay will probably be a linear amp so the switching relays dont need to be large they can be the small RF relays that are pcb mounted
Any ideas?

Re: IC-705 antenna switch from band

Ken N2VIP
 

If your goal is to simply switch between a single multi-band HF antenna and a dual band VHF/UHF antenna, the losses of a single duplexer could be easily overcome by using higher-gain antennas or lower-loss feed line. A single duplexer has very minimal losses, for example, this Diamond duplexer has about 0.2 dB signal loss maximum:


If you decide to employ a CI-V interface, a band switch and antenna relays, you will incur a significant expense ($200?) and still have signal loss (no switch I'm aware of has NO loss). For example, this popular Ameritron RCS-4 antenna switch has 0.1 dB loss at 3.0 MHz:


Don't like MFJ/Ameritron? How about this SSB Engineering part, which is better suited for applications that include both HF and UHF band signals? It has a specified 0.15 dB loss/attenuation:


I like the low cost ($75?), simple, duplexer option for remote operation, it requires zero interaction by the operator, and can be placed anywhere along the feed line, potentially saving on feed line expenses.

My advice, take another look at the losses involved - you may find the popular concern about loss to not be nearly as bad as others suggest.

Final note - even a simple, mechanical coax switch - which would be impractical for a remote setup -has about a 0.12 dB insertion loss:

Daiwa CS-201A 2 Position Coax Switch 

https://smile.amazon.com/dp/B00HYJPU8W/ref=cm_sw_r_cp_api_glt_i_03P5KD11FBY255DQ57KB

It looks like the only way to avoid signal loss is to manually switch coax connectors as you switch bands.

I want to be able to change antennas via a remote switch at the remote site. so when on the HF bands I can be on a HF antenna and when on VHF to be on a VHF antenna and the same for UHF. Each will also have a linear amp on them for the correct band.
Others have said to use a combination of duplexers but that introduces too many losses. It would be better to use a relay based system. The relays of course only need to be small RF ones due to the 705 power

Re: IC-705 antenna switch from band

Pedro S - EA3FNM
 

I think that, for vhf and uhf is better to use duplexers than relay based switch's and for this reason I will use duplexer for this solution.
And it is an passive device and this means lees problems for remote stations.

Re: IC-705 antenna switch from band

VE2DX
 

looks like your message was sent twice...

ok well yes the CT17B-6BT will help you by creating CI-V ports for connecting external CI-V devices to your 705.

then all you need is to select the best CI-V based band decoder there are many, I like Bandecoder II... mine is coming but not ready yet!

Hope this helps

How can I hook up my 705 to a CI-V device?

VE2DX
 

The IC705 does not come with a CI-V port, thus many hams are stuck without any possibilities to control other radios or devices via CI-V.

The VE2DX CT17B-6BT is a CI-V with a Bluetooth interface, it was created to help hams isolate the Computer side of the shack from the RF side of the shack, with the arrival of the IC705 the Missing CI-V port was a problem, we were able to use the CT17B-6BT by creating a Bluetooth link between the IC705 and the CT17B-6BT thus creating 5 CI-V ports for the IC705 to control other ICOM Radios, ICOM or OEM CI-V compatible devices like antenna controllers, amps, etc...

Large station CI-V Operations

VE2DX
 

When automating your ICOM Radio stations you will likely be using CI-V here are a couple of things to keep in mind when you do especially for larger multiple radio stations.

1- Collision, when you have multiple radios and other CI-V compatible devices all talking to each other on a single CI-V Bus you may (WILL!) encounter collisions.  In most cases other than a bit of latency you will not notice any issues.  But some devices especially the IC-PW1 (Note 1) are known to be affected in a major way by those.  

Split your CI-V Bus into radio oriented segments; if two radios DO NOT need to talk to one another, split them up using separate CT17B hubs or simply pull the JP1 from under your CT17B-10 Series (10, 11Usb or 12 Dual USB) to split it up into two distinct hubs, by doing this the two or three separate hubs can operate on there own.
   
2- DON't use Tranceive mode unless you need it, and you may need it to make certain your non-ICOM CI-V devices be able to sniff the data from the targeted device on the CI-V Bus. but if not disable it.
   
3- Some Non-ICOM devices send a data request on the CI-V Bus to the targeted device to get needed info to operate, like Frequencies, mode, or Band...  If your device does adjust the latency to keep those requests as spaced apart as possible.


----WARNING--- this last suggestion WILL add latency to your device and may have a negative or even damaging effect to your station, know you devices properly before doing this!


4- if your radio offers USB CI-V access USE IT, the trick here is to echo your CI-V data on the CABLED CI-V Port (Remote) to your other devices using the CT17B Hubs if needed. This does help in managing your CI-V traffic on your CI-V Hub.

5- Use proper Mono 1/8 cables on your bus, using Stereo cables may work for now, but IT WILL make you eat your lunch after adding other CI-V devices that don't support Stereo cables, I know I DID

6- USE Ferrite cores on all your CI-V cables, even if all VE2DX CT17B and IAB series devices are RF filtered, you NEVER have enough RF filtration.

7- Bring your CI-V speed up as high as possible, this will help manage latency. 

When running off ICOM Radio USB port (7300, 9700, 7610, etc...) that is probably 115.2k.
When running off USB rs232 port or USB-based devices like CT17Bs, that will vary according to your port configuration.

---NOTE--- Keep in mind if this is via a CT17B hub you WILL need to make certain ALL your radios and NON-Icom devices on the hub are running the same speed.
---NOTE--- Newer ICOM radios like 7300, 9700, 7610, etc... have separate CI-V speed configurations for the USB CI-V and the CABED CI-B(Remote) Port, if echoing the data, the speed conversion will be done by the radio! NICE! :D

8- Know how to properly configure your Control or logging software.  improperly configured software can and WILL cause you problems with connections, latency, and other issues. KNOW YOUR SOFTWARE!

Hope this helps

Re: Looking for an ICOM IC-705 for Bluetooth tests

VE2DX
 
Edited

Sorry but for now my CT17B-6BT does not have an audio codec. :(

you could try to use a CSR type USB Bluetooth adapter, most of these (be careful... most!), support when used in Windows10 both data and audio links via Bluetooth.

thus you should be able to link your 705 to a Windows10 in both data (CI-V) and audio, but... sorry there is a but, the data speed will not be as high as usb, some application with panadapters like Win4Icom need high speed CI-V limks foe functions like these...

I hope this helps

Re: Looking for an ICOM IC-705 for Bluetooth tests

   I know how to setup the IC-705 for WSJT-X
with a USB Cable between the IC-705 and a PC
and have done that before many times !

What I want to do is NOT use a USB cable and do it 
with Bluetooth ( No USB Cable ) BT for both Audio and Data 

Tried via the WLAN Server and no luck, apparently 
the RS-BA1v2 Utility when connected to the PC 
only allows one to use the Icom RS-BA1 software 
and Virtual Port fine but if you try to use the Icom
Virtual Port it does not want to share it for WSJT-X 
on a Windows 10 PC, even Com0Com will not
share a Pair with the Icom Virtual Com Port 

So the only other method is via Bluetooth to
link CI-V and Audio Incoming and Outgoing
to WSJT-X from the IC-705 Bluetooth BT 

That why I thought you might know about how to connect Bluetooth BT from a ICOM IC-705 to WSJT-X without
using The typical USB cable approach which seems to
generate RFI in the HF Bands

OH! MAN! Dan! you're killing me! (Don't tell my XYL Guys!)

Like I responded to Mike below, this works fine in Windows, now I really don't know anything about the Pi Server you guys are using (Sry!) but, just like in windows you SHOULD (????) be able to access both the audio Codec and CI-V Data port...

Maybe there are users of that PI Server in the group (PLEASE! Jump in!!!)

send me reference data or links to that server I will be happy to into it (no promises!) at least this way the wife wont know about me not pushing sales more :P 

Warning Sales Pitch coming: guys drop by WWW.VE2DX.COM for more info on my stuff and also drop into the used and book section! See Moose (canadian version for DEER! Get it DEER... Moose!!!) I tried!

Dont have to be crazy to be a canuc but it helps!
