When I powered on the radio, two new serial ports were created. When I setup the radio initially, I removed my FTDX-3000 and connected the FTDX-10. I know that I have the correct ports selected because I only have two of them. Something is not right with the serial ports. Fldigi is processing the message because I see it on the screen. Last night I decided to check the PO level. I was switching to ALC to monitor my sound levels when sending and did not have any movement scale. I adjusted my Fldigi settings to match the information that Gary provided and still could not get an answer to a CQ, or get reply from a station calling CQ that I answered. I finally realized that I have a problem worse than incorrect settings. That way you can just click the digital signal and everything aligns. I generally like a wider bandwidth while tuning around, so the DATA-U suits me better. You still have to select RTTY in the OpMode, though. If you select RTTY using the box in the upper left corner of FLDigi, the rig will switch to RTTY mode, i.e., narrow BW with the M-S (mark/space) tuning window. Change to Data-L or RTTY-R (reverse) FYI, the RTTY decoder in the rig doesn't hold a candle to FLDigi. I found RTTY on LSB today, which is really the way it should be. FLDigi operation Packet USB = Data USB and your rig will change to that. Rig settings Set Radio Settings, Mode PSK/Data - Data mod source = rear Rear Select = USB AMC = 25-30 Set TX power = 100 watts Click the "Tune" button on Fldigi Adjust Windows volume, i.e., Speakers(USB Audio Codec) for 30-35 watts output. It will pick up your frequency and mode automatically. I changed mine to 38,400 Restart FLDigi to be sure. To route the sound from browser audio output to Fldigi audio input I've used a Mac software called Soundflower, although worst case you can just connect a cable from your computers line-out to your line-in.I got FLDigi up and running today as follows: Rig Control = Hamlib Use the Yaesu FT-991 rig from the list Checkmark "Use Hamlib" Checkmark "PTT via Hamlib command" Uncheck everything else Set your baud rate to the rig setting. If you do want to have a try without spending a pence, there's a directory of WebSDR sites, where you can tune via your browser and then hook up the sound output from there to Fldigi to decode Weatherfaxes or whatever else you want to. Haven't had the opportunity to try this yet, as when people do let me sail on theirs I don't really want to arrive with a box of radio kit, so this will have to wait until I'm done boat shopping myself I imagine if they work on my balcony with houses full of EM spewing kit all around, they'll work much better on a boat with a mast antenna and no houses. For Navtex I used a ferrite rod loop (eBay or slaughter an old radio). The FunCube comes with a minimalistic tuner app that should work on any platform.įor an aerial I plugged in a cheap VHF TV antenna (two sticks + loop) and got a reasonable quality fax on my balcony (even one from the DWD in Germany). GNU Radio supports a wide range of receivers, and depending on your choice of OS there's several other options. You do however also need a bit of software to set the frequency and a few other options. Most of these work without extra drivers, they simply emulate a soundcard and output the raw I/Q streams on the left/right channels of that soundcard, so they will work with pretty much any software. You can also use it as an extremely overpriced multi-band broadcast radio receiver as well as listens to HAMs, tune in on radio clocks and whatever other interesting/useful stuff is out there. I got the FunCube because it covers a very wide spectrum at a pretty good quality and is the only one that can tune low enough to get Navtex as well. Somewhere between those two extremes are the FunCube and the HackRF (which can also transmit). I assume they're good, never had the opportunity. On the top end of the range, there are professional SDR receivers like the Microtelecom Perseus (~£600) or various FlexRadio or RFspace models (>£1000). These however only cover 24 MHz and upwards, so you'd also need an RF upconverter in front of it for receiving Weatherfax. The standard cheap SDR hardware is known as RTL-SDR and is based on the Realtek RTL2832U chip available very cheaply (~£10) in the form of USB DVB-T (terrestrial digital TV) dongles.
