Config file help

[n9bhd]

Hi Dan. Makes sense that the two programs might use different calibration data. Looking forward to trying out a config file when available just to see what happens.

Hi Dan. Anything new on the kachina config file? I'm sure you're busy with other work but I was just wondering.

Hi Vic,

I've done some changes in the app to accommodate DDS multiplier parameter in the config file to help calculate the frequency for some transceivers like Kachina. I will post an update here later today for you to test it.

Thank you.

Thanks Dan! Looking forward to the update.

Hi Vic,

The release will be postponed for tomorrow, as I've found a bug I want to fix before.
I'm really sorry for the inconvenience.

No problem Dan. Take care.

Hi Vic,

I'm almost ready to send you a new version to play with it, but there is still something which I do not fully understand from the document you've sent.

I've seen there the following commands:

(STX)R byte3-0(ETX) DDS value for receive frequency. The allowable range will be 30kHz to 30MHz. The uppermost 2 bits of the high byte will indicate antenna port as follows:
00 - port B/A
01 - port A
10 - port B
11 - port A/B
The DDS value is computed using:
DDS = 2.2369621333 * (75000000 + freq) where freq = input frequency in Hz.

(STX)r byte3-0(ETX) DDS value for reference calibration frequency. The allowable range will be 30kHz to 30MHz.
The DDS value is computed using:
DDS = 2.2369621333 * (75000000 + freq) where freq = input frequency in Hz.

(STX)T byte3-0(ETX) DDS value for transmit frequency. The allowable range will be 30kHz-30MHz (the radio will restrict the range to 1.8-30MHz). The uppermost 2 bits of the high byte will indicate antenna port as follows:
00 - port B/A
01 - port A
10 - port B
11 - port A/B
The DDS value is computed using:
DDS = 2.2369621333 * (75000000 + freq) where freq = input frequency in Hz.

Can you provide an example command showing how to set the frequency? I suppose you set separately Tx and Rx frequencies.

It seems to be a very difficult to handle protocol comparing with other transceivers.

Thank you.

Hi Dan. I'm sorry I don't know how to provide you with an example set frequency command. I currently use kcat on my windows pc and the program sends commands to the kachina via the serial port connection. I can click on a preset frequency like 14070.000 for 20 meter psk and the kachina just goes there.

Hi Vic,

You set the frequency separately for Rx and Tx?

Hi Vic,

Till I solve the frequency set command, please test the version 0.7.1-24 from here:
http://www.yo3ggx.ro/pocketrxtx/pocketr ... 7.1-24.apk
The following commands are implemented and allocated to some option buttons:
CMD_SET_MODE_xxx
CMD_SET_PWR_xxxW
CMD_SET_VFO_x
CMD_SET_NR_ON/OFF
CMD_SET_IPO_ON/OFF
CMD_SET_ATT_ON/OFF
CMD_SET_AGC_OFF/SLOW/FAST/AUTO
CMD_SET_NB_ON/OFF
CMD_SET_ATU_ON/OFF
CMD_SET_ATU_TUNE

The following commands are implemented but not allocated to any button yet (you can configure the buttons as you wish):
CMD_SET_AMP_ON/OFF
CMD_SET_FILTER_xxxKHZ
CMD_SET_SIMPLEX_ON
CMD_SET_LISTEN_RX_FREQ
CMD_SET_LISTEN_TX_FREQ
CMD_SET_SPLIT_ON
CMD_SET_SPEECH_PROC_ON/OFF
CMD_SET_PREAMP_ON/OFF

No feedback yet in the config file as is still not very clear how to read some of the values.

Please test the available commands and send me your feedback here.
After you install the new version, run the application and long press on START button and then on RADIOS button to load the updated embedded config files. You must do this only at first start after the upgrade.

I will start tomorrow to work on an updated user guide as version 0.7.1-24 has a lot of new not yet documented features.

Thank you,
