    Good USB Cable:

    Just as an aside, I have been trying different cables to connect my X108G to my And roid Smart phone to use PocketRxTx. Often needeing to have adapters as the connector on the phone is the new USB-C type not the old micro-USB and also as the Smart Phone has to see a line lifted in voltage in the usb-0C plug so that it knows to work as the "host" not the "client" (the so called OTG or On The Go function).

    As I was getting interference from the smart-phone into the X108G receiver, I have tried different ferrite clamp-on and ferrite core solutions and longer and longer cables until the USB signals were lost. I found a plug-in board that does a good job of filtering RF noise but this is a board and two cables (one of them using an USB-Mini connector).

    I was surpised when a couple of months ago, I came a cross a USB-C to USB-micro cable which was supposed to have OTG wired at the usb-c end. Well for 0.99 UK pence (Euro 1.15) including postage, I decided to order one. It took some time to come (from China) but I am very happy to announce that this cable works AND despite (or perhaps because of) its SHORT length doesn't seem to transfer the phone-noise into the X108G's receiver!

    Here's a link to the cable on eBay.

    Ah, that makes sense. I will get the readings, but it might take a while. This weekend we have a field day, and then I'm travelling for work for a week. Added to that is the fact that the G90 doesn't have an RF gain control. I'll rig up an attenuator to get the S levels. What command do I need to send?

    Hi Tim,
    No need to set up an attentuator - just tune off the side of a signal until you get the various values on the S-meter on the G90. No RF gain control? That seems a bit satrange to me but I know SDRs are different.

    You will need to send the command from a terminal program (by the way when v4 of PocketRxTx and JaREc are released Jarec has a terminal program built-in exactly for this use. I use the windows program "RealTerm" at the moment but any character based terminal program will do.

    The X108G and hence I hope the G90 is auto-speed sensing on the USB port but for the other settings use 8N1.

    The command (without the commas) is FE,FE,70,E0,15,02,FD (this is to be sent in Hex Mode).
    The rig will return 9 characters and it's the 8th character that we are interested in.

    I use for Remote-Control the RCForb Software. As Radio use the ICOM IC7000 Settings.

    The CiV protocol for the X108G is not documented ANYWHERE!

    Start with the ICOM IC-7000 commands and then test which work and which don't (or work differently).

    Hi Ed - sorry I've been out of the loop on this for a while (life keeps getting in the way of radio...). The attached CIV reference is now doing the rounds on the FB groups. Hope it might help you with the PRxTx definitions.

    Thanks for this. I'll compare this with what I have in the config file for PocketRxTx for the G-90 and if needed, get a new Radio configuration file uploaded to the central repository so those wanting to remote control their G-90 can do so easily from their Android Smartphones and PocketRxTx (either free (with adverts)) or the full $5 paid version. My advice is to try the free version and if you're happy, buy the full version (it's cheap enough and we should support the author - which isn't me!). Currently, version 3 is in use and works well, version 4 is planned with new features but as always the author is paying for development out of his own pocket.
    I issued a new radio file for the X108G to the Central repository a couple of weeks back - no major changes just added an extra power level of 3W which is a good level to drive the Chinese 50/70/100W amplifiers at.

    Cheers Ed. I do have the Pro version, and will encourage others to upgrade. It's a great app. I know of one chap with a dead display on his X108 who's still happily using the rig thanks to prxtx.

    Hi Tim,
    when I found that the OLED display in the later X108G that I have is totally un-readable in any level of sunshine (XIEGU changed from a TFT screen with contrast and brightness controls to an OLED display with no contrast or brightness adjustment on the basis that in the outdoor model it "would be easier to see the OLED display" - you got that one TOTALLY WRONG Xiegu designers!) I started looking for some way to get an external display on the rig which is what led me to PocketRxTx. When I contacted Dan, the author, I found him to be very helpful and open to extending the models supported by his program (which has been around many years by the way).
    I've now managed to get to use my OTG supporting An-Droid Smartphones (note several phones say they support OTG and even test programs say they do, but they don't) connected either via USB (Micro USB and USB-C) to the X108G or over the LAN/WAN using a Raspberry Pi so the RPi is connected via USB to the X108G runs a free server program and from there I can connect and operate the rig from anywhere that has Internet connectivity (either via WiFi or Cell Phone data network). As the major part of the processing happens on the phone, the solution is very responsive. (unlike the new MFJ solution, which doesn't support the X108G in any case I think, and has the user GUI web-based and is only limited configurable).
    I also have tried to get PRxTx to work with the X-108G over Bluetooth. In this case, as the rig has no "true" serial output only the USB socket I was unable to make several different solutions work.

    Now the G-90 has a "true serial port" (and no USB), so one of the Chinese Bluetooth dongles may be able to be made to work with the G-90.

    All in all, it's taken a while to get the PocketRxTx remote display / remote control solution working but it certainly makes using the X108G portable much more enjoyable than it was.

    Hi tscrim1,
    I've just put up a test G90 (v2) on the central repository - if you have a G90, could you please load this and test the following functions to see if they are now working please:
    New 3W power option (used to drive the Chinese 50/70/100W power amplifiers)
    AGC - according to the chart supplied this feature appears to use a different setting on the G90 to the X108G.
    ATU (NEW) - on/off/tune.
    Speech Compressor (NEW) - on/off
    Noise Blanker (NEW) - on/off
    Squelch slider, when Pre-amp turned on (doesn't work on X108G may be fixed on G90).
    Tuning step (location of cursor in display) - works on X108G but not listed as an option on the G90 CiV command sheet so might not work on G90.
    SWR values shown - presently calibrated for the X108G - may be way off in the G90.
