2BSIQ SO2R with Flexradio-6700 and N1MM+

To be able to work high rates on contests there are several techniques. Popular is of course SO2R but there several methods to accomplish this. Jose CT1BOH suggested the 2BSIQ technique which is quite attractive.

The fundamentals are:

1. Send TX on radio A and listen with both ears on radio B.
2. When you end TX on radio A you get stereo mode and hear both radios in the ears.
3. When you start TX on radio B back to both ears to radio A.
All this done automatically w/o tilde button.

Here is a video demonstrating it. There is no CW side tone sound as you always listen to other radio for callers while sending CW on the other radio.

How to add remote contest capability to Flex-6000 without a remote PC

Flex-6000 series is a great contest radio. However, when running contests from a remote location present SDR software cannot produce local CW sidetone unless you use the built in CWX keyer and NOT use a logger program to automate it all. Same with Flex Maestro who does produce local sidetone but you cannot integrate with a local PC contest program (easily).  Flex will eventually come up with a solution soon but till then we need a solution. The solution is the Remote Rig concept. Easy and not expensive (you may find these at the local swap market).

How to do it

You may use Remote Rig boxes to produce local CW sidetone very easily. At the remote radio end I have no PC (to risky in my opinion) only the remote rig 1258 MKII radio box. This box has CW keyer output that I connect to the FlexRadio front panel CW key input . It has also a Audio input that I connect to the FlexRadio front panel Audio output. At home base I have the Remote rig control box which is connected with a USB cable to my PC with N1MM or WriteLog. The control box automatically creates virtual COM Ports for CW keying with Winkeyer emualation (at the radio end) that I choose in the N1MM configurator for CW keying.
So when I do N1MM or WL CW keying at my home base PC the remoterig radio box keyes the FlexRadio. At the same time the audio output from the FlexRadio is routed back to the Remoterig control box at home base and I can hear the CW side tones. This works very well and is 100 % rock solid.
No VPN is required. Just regular internet. SmartLink can be used. The bandwidth required is about 300 kbit/s depending on the audio quality of the remote rig audio (there different compression levels).
With the remote rig boxes comes two COM ports that you may use to control RS-232 devices as well. Rotors, wattmeters etc. You van attach your Morse key paddle to the remote rig control box and get local sidetone as well as keying the Flex remotely.
So this is the only way today to get local CW side tone when doing remote contest CW.

RRC configuration

Here screen shots from the confuguration pages of the RRC boxes. I use COM Port 3 (COM Port 1 may also be used with a USB cable). Just find the corresponding Windows COM port (in the device manager) and use that for CW keying in the logger program. That´s all to it. 🙂


New contest simulator even for SO2R and Flexradio!!!

So how can one improve in contesting. SO2R is one trick. It is all about tehniques. How do you train then? Why not in a simulator. I have tested all that around that suits Flexradio. Here is how it looks like in SO2R mode with band maps showing station activities. Very handy and effective I must say. In my opinion the best Flex simulator on market today. A more detailed evaluation soon to come.

New CSS from Wayne W5XD.

Here the simulator is configured for radio 1 and at 3550 kHz and radio 2 at 3580 kHz. The “peaks” of the band maps are actual stations calling you. With the thumb wheel you can change frequency and chase  new S&P stations. I even find the simulator when doing S&P on radio 2 that “SM0HRP” was calling me. As I understand it uses the Super Partial database for simulating callings stations and I am in there after a few contests.

Please be aware that you can use CSS with WL demo version with some minor limitations. Mainly to the number of contests to choose from.

Configuring Writelog with Flex-6700 for SO2R

Being a little fanatic about SO2R it is interesting to see what logger program will work well with Flex-6700. The fact that Wayne W5XD came out with a new Contest Simulator recently with lots of nice features it draught my attention. So how do you set up 6700 for Writelog (WL)?

I am using an external Wineyer at OCM12 and 9600 baudot. Here is a screen shot of the configuration.

Configuration of 6700 with latest WL.

OBS! Two use two slices on different you must actually set up four slices. A pair for each band. New drivers can be found on WL page.

How does it work then? Really well in SO2R mode.
