Linrad wants the emedirectory to be C:\emedir, NOT \home\emedir or > C:\home\emedir as in Linux [not documented that I can see]. Feedback is really scarse as you know. The number of postings on this list is pretty small ;-) In the help file you can find this: -------------------------------------------------------------------- [301]INITIALIZE THE EME DATABASE If you did it before and do not want to change anything, press enter or any other key except M to use your old file: /home/emedir/linrad_dxdata (Linux) C:\emedir\linrad_dxdata (Windows) ************ In order to decide what polarisation to use for transmit Linrad has to know the geographical location of the other station. There are files on the Internet containing this information. Make a directory /home/emedir for Linux or C:\emedir for Windows and copy the data files there so Linrad can find at least one of these files: /home/emedir/allcalls.dta or C:\emedir\allcalls.dta /home/emedir/eme.dta or C:\emedir\eme.dta /home/emedir/dir.skd or C:\emedir\dir.skd /home/emedir/CALL3.TXT or C:\emedir\CALL3.TXT (Search for emedir.exe allcalls.dta, CALL3.TXT and vhfsched.skd on the Internet) Linrad will create the file own_info, a file containing your own location, UTC offset and whether the EME database should always be installed so you will not have to press M on the main menu. The database will occupy some memory and you may want to use memory for other purposes now and then on a small computer, that is why you have an option here. Linrad will also create linrad_dxdata which contains the data from all the files in Linrad's own format. If the files contain incompatible information, the file location_errors.txt will report the errors. All files are created in /home/emedir(Linux) or C:\emedir(Windows) Once the EME database is initialized, the EME window can be used for finding call signs by a search for fragments using ? and * as "wildcards" ---------------------------------------------------------------------- The above message is shown if you press F1 for help in the init procdure: lir_text(5,5,"Press M to update, F1 for help."); The emedir directories should have been specified in options.h as all other directories used by Linrad.

OK. Seems this file has changed its format one way or another since I adopted Linrad to read it. I will look into the EME data base issues for the next Linrad version but before that I need to know which files besides call3.txt that are still available and reasonably up to date. > 4.

Since I still have no antenna, I will only act on feedback from others. Hopefully this will change, I am slowly building the tx side of Linrad towards the antenna. I just made a 2x15V power supply with three transformers to give me 15V from a 3-phase unstabilized power supply to feed 2x WSE RX converters + one set of TX converters running simultaneously. One RX chain is for "normal usage" on the main computer. The other is connected to a second computer to serve as a spectrum analyzer to check the performance of the TX chain that is connected to the main computer. Right now I have a good signal on 10.7 MHz (CW/SSB 10.688 to 10.788 MHz) > I am very suspicious that all of this is old information and that I am > having a major deja vu experience, but figured I would send this to the > list after Google failed to give me what I need ;) > > All of this came about as I was preparing to give a lecture and 'how > to' session on Linrad tomorrow.
