![]() The price of an IC-V80 on ebay is comparable to the higher wattage baofeng HTs. It’s working fine for FSQ, including photo transmission with that mode. This article indicates that Digirig PTT control over the baofeng is possible, I just havent personally tried it yet: VHF/UHF Digital Modes with budget HTs – digirigįor HT transmission with fldigi I just picked up an icom IC-V80 sport, and the proper Digirig cable. You might opt to set the radio to transmit at lower power too, to keep the radio from heating up. If you choose to stick with the baofeng, I recommend turning off the battery saver in the baofeng settings menu (you need the receiver on and listening 100% of the time), and activating a half second pre-signal tone in Fldigi under Configure | IDs | RsID. ![]() But, the limitations of that radio were a constant struggle. This could be remedied by upgrading equipment, selecting a faster digital mode, or transmitting fewer characters (send the information directly from fldigi without all the extra characters transmitted by an flmsg form).Ĭontinuing our convo from the other thread, I have made a baofeng work with fldigi using other brands of cables (utilizing VOX), so I know the radio is capable of digital modes transmission. If it is too hot to comfortably touch after 2 minutes of transmission, you may be exceeding the duty cycle of that particular radio, causing the transmitting radio to malfunction in unpredictable ways. Feel the case of the transmitting radio.If you have TOT set for 120 seconds, the transmission will stop after 2 minutes. Note you may need to use the sudo command depending upon how the package was installed and who has ownership rights for the package. apt-get clean package name to clean up the local repository. Check the time out timer in the settings. apt-get purge package name to completely remove the package from the system.Of course also double check the simple things like frequency, wide/narrow band, that the antenna is screwed onto the radio, connections to the digirig, and make sure offset is turned off for simplex use. With a Raspberry Pi you can run many popular radio programs like WSJT-X, FLDIGI, Winlink, and APRS. If you have non-compatible CTCSS codes, you may not hear the transmission from the second radio even if the first radio is transmitting properly. on the Linux language and most of the software is open code. Make sure the CTCSS codes are turned off on both radios.At the risk of overexplaining, here are some things I would check: Yes, if one radio is transmitting correctly, you should hear noise on the other. I think I understand what youre describing about the behavior of the baofeng. I just learned how to do that on the pi, and posted it here if you need it: Auto Gain Control in Linux? Hello Genius Pi programmers (and barely literate users like myself ) I am setting up a Pi2 for use with Amateur Radio digital modes, using a program called Fldigi. All those levels are managed through alsamixer on the pi. you should use some demodulator to decode the audio first.Oh. Mumble, WSJT-X and Fldigi use the Raspberry Pi audio system, either. Like hinted, you can not really input IQ data straight into the dongle. Click Pi Menu>Ham Radio to access the added ham programs. In any case, you probably now see a lot of DC content (zero hertz has a lot of power around it). Various things can upset this hack, including mixing the I and Q together to form a mono signal, and so-called phase noise of the dongle. What happens is that if you tune sufficiently close with the dongle to the actual reception frequency, the IQ data can also be seen as already demodulated data if you just take the I (or Q) channel, i.e. You are now using a "hack" to receive the IQ data as normal audio without knowing it. I can see the datastream in the waterfall and it does decode parts correctly, 10 chars in a row or so and then it stops decoding correctly. ![]() ![]() Then I select the FCD Pro+ as an input device in dl-fldigi. Before connecting the Digirig to the transceiver, I set up the rig in fldigi, making s. I made some homebrew cables, after carefully studying the Digirig schematic and adding some important modifications to my old Icom IC-751A. Currently, I use qthid to control the FCD Pro+ and set the correct frequency. I used KM4ACK’s excellent Build a Pi script to set up a Raspberry Pi for radio tasks.
