remote software CW keyer with ASIO side tone
Hi folks,
I'm just working on a remote cw keyer for my Flex-6300. The cw key is attached to the PC via USB-RS-232. The side tone is generated via low latency ASIO audio. This already works just fine.
Based on the information given from KE5DTO and NQ6N here
I want to key the radio via network.
I have already download the FlexAPI v3.1.8. I was able to connect to the radio according the example ComPortPTT from the FlexAPI. This is my Forms1.cs:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Flex.Smoothlake.FlexLib;
using Flex.UiWpfFramework.Utils;
namespace Iambic2
{
public partial class Form1 : Form
{
private Radio _radio;
public Form1()
{
InitializeComponent();
WindowPlacement.SetPlacement(this.Handle, Properties.Settings.Default.WindowPlacement);
API.ProgramName = "ComPortPTT";
API.RadioAdded += new API.RadioAddedEventHandler(API_RadioAdded);
API.RadioRemoved += new API.RadioRemovedEventHandler(API_RadioRemoved);
API.Init();
}
void API_RadioAdded(Radio radio)
{
if (_radio == null)
{
_radio = radio;
_radio.Connect();
//UpdateMox();
//_radio.CWPitch = 650;
}
}
void API_RadioRemoved(Radio radio)
{
if (radio == _radio)
_radio = null;
}
public void RadioTriggerOn(double timeStamp)
{
//Console.WriteLine("On - " + ((int)Math.Round(timeStamp)).ToString("X4"));
_radio.CWPTT(true, ((int)Math.Round(timeStamp)).ToString("X4"));
_radio.CWKey(true, ((int)Math.Round(timeStamp)).ToString("X4"));
}
public void RadioTriggerOff(double timeStamp)
{
//Console.WriteLine("Off - " + ((int)Math.Round(timeStamp)).ToString("X4"));
_radio.CWKey(false, ((int)Math.Round(timeStamp)).ToString("X4"));
_radio.CWPTT(false, ((int)Math.Round(timeStamp)).ToString("X4"));
}
}
}
RadioTriggerOn() / Off() are called at the according time instant of the side tone. timeStamp is counted in milliseconds with rollover at 2^16.
With this programm the radio does not send out any HF. I can see no reaction from the radio except that the normal CW key plugged into the radio itself does no work anymore after I have pressed the RS232 CW key a least one time (no HF is send, side tone works as usual). I have to reboot the radio to bring it back to normal operation.
I have noted that CWKey() is specially designed for the Maestro. So I have changed line 1763 of Radio.cs as follows:
if (true) //(API.ProgramName == "SmartSDR-Maestro")
What changes are necessary to make this program work?

Update:
When I switch from CWKey() to CWKeyImmediate() in the code above the radio is keyed properly. So there is obviously a problem with the generation of my timestamps.
With Wireshark I can see "ping ms_timestamp" messages on TCP port 4992. My timestamps are not in sync with these timestamps. Moreover the timestamps in CWKey() have a different format (hex integers) than the ping timestamps (decimal numbers).
Is this the cause of my problem? How can I get my timestamps in sync with the timestamps already sent by SmartSDR?

Update:
with the following code CWKey() works. Nothing was wrong with the timestamps. Instead the appropriate _guiClientHandle has to be provide to CWKey().
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using Flex.Smoothlake.FlexLib;
using Flex.UiWpfFramework.Utils;
namespace Iambic2
{
public partial class Form1 : Form
{
private Radio _radio;
private uint _guiClientHandle = 0;
public Form1()
{
InitializeComponent();
WindowPlacement.SetPlacement(this.Handle, Properties.Settings.Default.WindowPlacement);
API.ProgramName = "ComPortPTT";
API.RadioAdded += new API.RadioAddedEventHandler(API_RadioAdded);
API.RadioRemoved += new API.RadioRemovedEventHandler(API_RadioRemoved);
API.Init();
}
void API_RadioAdded(Radio radio)
{
if (_radio == null)
{
_radio = radio;
_radio.Connect();
_guiClientHandle = _radio.GuiClients[0].ClientHandle;
}
}
void API_RadioRemoved(Radio radio)
{
if (radio == _radio)
_radio = null;
}
public void RadioCWKey(bool state, double timeStamp)
{
if (_radio != null)
{
_radio.CWKey(state, ((int)Math.Round(timeStamp)).ToString("X4"), _guiClientHandle);
//_radio.CWKeyImmediate(state);
}
}
}
}
