We offer a large range of interfaces to ensure maximum compatibility with modern and older PCs and digimode software. There were plenty of Linx8 on eBay when I looked at good prices.Icom CAT control and Digital mode interfaces to use software such as Ham Radio Deluxe, FLDigi, WSJT-X to operate PSK31, FT-8, JT9, JT-65, Echolink and many other AFSK modes. It would be good to know if there is a better driver but the fact it works is nice to know. Using a USB dongle set to 16bit/48kHz solved that problem as 48kHz was not supported by the on board sound.Īs I said, I think the drivers in Win10 for the Linx1010 have been updated as it now offers 4410 rates and I’d put money on the fact it never used to do so! The Linx8 is the same hardware as the Linx1010 apart from the screen IIRC so it could be just a driver issue. I know that when I tried JT9 and JT65 on my 7in Windows 8 tablet, I could not get any decode using the on board sound. Click on Properties, then Advanced, and select 16 bit, 48000 Hz (DVD Quality). To ensure that this will be so when running under recent versions of Windows, open the system’s Sound control panel and select in turn the Recording and Playback tabs. "WSJT-X expects your sound card to do its raw sampling at 48000 Hz. This quote is from the online docs at Joe Taylor’s K1JT web page (but it is for 1WSJT-X 1.6) I got the requirement from the WSJT docs. This would enable us to see if it was a suitable mode for SOTA using old/cheap equipment. If anyone is interested or willing to try out FT8 there is lots of activity on 7.074, 14.074 and when conditions allow 50.313 on something slow. On my i7 PC there is not much of a noticble difference in decode time, but considering its less than a second on JT9 its very hard to measure. Due to the fact I dont have any old PC’s lying around, I can’t gauge what the decode time is like on the processor, or to be more precise, what the decode time would be on some small portable intel device. Also if portable the amperage per qso would be lower giving obvious benefits for battery requirements. This results in decodes to about -20db rather than -26db but the gain is in shorter transmit/receive times which can overcome propagation issues such as qsb. A total qso time of 1 minute versus 4 minutes. The QSO structure of FT8 is the same as JT65/9 qsos but the main difference is that the transmit/rcv segement is only 15 seconds opposed to 1 minute for JT65/JT9. I tried it out at home on 20m and 6m and it works great on both. In a recent update of WSJT-X (1.8) there is a new mode FT8. I know that a few people here use datamodes for SOTA including JT65 and JT9.
