Would it be possible to utilize FEC when recieving a brodcast?

Thanks for the reply Irad. Yes of course, that was wrong thinking from me. One to many can not use FEC and ARQ. 73/Torbjörn

Thanks for info, I knew about the mouse trick. In our group we use Broadcast for EMMCOM use. During the last exercise when I after some text gave order to the next responder to send an information, that info was mostly not seen by anyone. The three dots that indicates that there is more text to the right was mostly not observed. So it would be most welcome to get text wrap also in the Broadcast section. Double clicking will not open the message row in a separat window, but instead invokes the "Broadcast message" window predestined to however was the sender of the received row. 73/Torbjörn

Hello Irad, Functional CAT-command files for IC-728, IC-725 and IC-735 can be found above. I made a reply to myself instead of making a new comment. /3/Torbjorn

Hello, The previously submitted CAT-files for IC-728 and IC-725 are now verified functional both for setting from VarAC main window and read-back to VarAC when changing frequency on the radios. However the IC-735, did not work. For IC-735 I had to adjust ReadFreqVfoA_Result_Freq_Start_pos to 11 and Length to 8 as seen on the copy of the CAT-commands below. This is verified functional. The old IC-735 shows only as last digit 100 Hz-figures, however it can be adjusted to 10-Hz by slowly rotating the dial, this will show up on the VarAC frequency readout. To get the radio display to zero in on the shown digits down to 100 Hz one must press and release the kHz-button on the radio. The ability to change frequency down to 10 Hz does of course not mean that the actual transmitting frequency is that accurate. After careful alignment of an IC-735 according to the service manual I got as best +/-30-50 Hz, and that is very temperature sensitive. The spec says +/- 200 Hz at startup and +/- 30 Hz after 1 hour at 25 deg C. If aligned! 73/Torbjorn

Correction Henriks callsign is SA6HBR /3/Torbjorn/SM6AYM

Hello Irad, The problem to change frequencies using IC-728 is solved. My colleague SA6HBK, Henrik, in our EmComm group, realized that at least for our old Icom station IC-728 changing frequency on the radio involves the two steps: 1) Define mode (e.g. USB) 2) Define frequency. The problem was defining the mode. In ”Your” last cat-files the HEX-command 06 (write) was used, when we changed this to the command 01 (transfer) changing frequency from VarAC main window worked as expected. If the mode command was not correct then the frequency command was ignored. Without changing from 06 to 01 it was only possible to change frequency from the setting window, not from the main window. Therefore we conclude that there is some difference between using the Settings TEST and the main window dropdownlist. Example för mode change to USB on IC-728 (38): Last cat-file: FEFE38E00601FD (we used IC-707 (3E) as base) Our change: FEFE38E00101FD There is no setting for mode on the main page, I assume this is expected to be read from the radio. There is setting for mode on the Settings page. This is one difference. I enclose CAT-files for IC-728, IC-725 and IC-735. So far only IC-728 is verified, IC-725 and IC-735 might be verified soon. However I enclose the requested log files, the test was performed as follows: * VarAC set with Debug mode, was closed * Log file was erased * Var AC was started * In Settings USB 14105000 TEST was set (functional) * In Settings USB 7105000 TEST was set (functional) * On main page 14105000 was chosen (no function) * On main page 3595000 was chosen (no function) * VarAC was closed * Log file was copied and saved 73/Torbjorn/SM6AYM

Obviously that is not the case. As said with OmniRig Freq select works. I have tested with 2 different IC-728. The IC-728 that I have modified to 3E and 9600 bps works fine with selection IC-707. Maybe I should try to change to 9600 bps and keep 38, but then OmniRig worked at 1200. There must be some difference in VarAC code when using TEST and when using Freq select, could this be investigated, perhaps by Irad?

Here is the code: PTT is done by RTS [Icom IC-728] CmdType=HEX ModeUSB=FEFE38E00601FD ModeUSB_D=FEFE38E00601FD ModeFM=FEFE38E00605FD ModeFM_D=FEFE38E00605FD SetFreq_Data_method=BCD SetFreqVfoA_Cmd=FEFE38E005{}FD SetFreqVfoA_param_length=10 SetFreqVfoA_hz_res=1 ReadFreqVfoA_Cmd=FEFE38E003FD ReadFreqVfoA_Result_Data_method=BCD ReadFreqVfoA_Result_hz_res=1 ReadFreqVfoA_Result_Length=22 ReadFreqVfoA_Result_Freq_Start_Pos=11 ReadFreqVfoA_Result_Freq_Length=10 VarACStartCmd= VarACExitCmd= As mentioned before, frequency change can be done via TEST in Settings but is not possible on VarAC main window. 73/Torbjorn
