SOUND DRIVER:: OSS VIDEO CARD:: on-board on motherboard LINUX DISTRIBUTION:: RedHat LINUX VERSION:: 7.0 LINRAD VERSION:: 00-48 TEXT: Using only transceiver (approx. 3kHz) bandwidth.. sampling rate 8 kHz both input and output same sound card. I used the book "Linux for Dummies" which included the RedHat 7.0 CD. It was an easy install. Thanks to W3SZ for help with appropriate initial set-up parameters. From the Archives: Hello all: Thank you to SM5BSZ, Aaron Hanisko (helped me through my first ever Linux install), W3SZ, and G0RUZ for helping me very much along the way. I have LinRad running and have sound coming through LinRad DSP for first time (yesterday night)! Computer configuration is not my strong suit; I am a humble telecom guy. :-) My 144 MHz EME antenna consists of 8 x 2MXP28 cross-polarity yagis on 144 MHz EME, although I wanted to start simple. So currently I use just my single rx LDF7-50A feedline which I manually (from operating position) relay switch (center of array) from vertical (V) to horizontal (H) elements fed single-channel into LinRad (and I have a separate dedicated LDF7-50A tx feedline to the array). I use the Japan Radio Company JRC JST-245 HF (160m-6m) transceiver on 28 MHz CW-wide position (approx. 2.4kHz passband) behind an SSB Electronics LT2S: Mark 2 144 MHz transverter for both my rx and tx. So obviously my bandwidth is currently limited. But now that it is running, I hope to get settings for simple single channel mode figured out so I can hear weak CW sigs better than naked ear (what I used 100% before LinRad). I believe one of keys to success is hardware selection (Linux compatibility) so toward that end, here is what Aaron recommended (and all worked great): I wanted a dedicated PC just for LinRad: Motherboard is Pentium III 1.13 GHz PC133, PCI bus equipped with 256MB RAM (Crucial Technology) Hard Drive is Maxtor IDE 6L020J1 20GB CD-ROM is ASUS 52X max ATAPI-enhanced IDE interface Mouse is a standard 2-button PS2 mouse (type 5) Video Card is on-board on the above motherboard Modem is ActionTEC 56K internal PCI call-waiting modem Sound Card is Creative Sound Blaster Live! (used for both input and output), common sampling rate chosen: 8kHz initially) Monitor is a re-used Compaq Presario V400 15", nothing fancy 640-480 resolution, although I was able to get 800x600 to work also in LinRad. Operating system is Linux RedHat 7.0 using GNOME and running LinRad in GNOME terminal emulation program ("GNOME terminal": at lower left near "Main Menu" button). I referenced the book "Linux for Dummies, (3rd edition)" (ISBN 0-7645-0744-3) to step me through the Red Hat install, although it really was not very difficult. Note: This book includes CD set with licensed version of Red Hat Linux. To Red Hat, I added SVGAlib, and NASM by very easy to follow Leif's step-by-step directions at his web page. And the Linux radio (LinRad) program: LinRad 00-48. Initially we tried operating system: Linux Slackware and while that worked generally OK, I could not get the mouse to behave properly in LinRad under Slackware so in the interest of being on common platform with many other users, I changed to Red Hat 7.0 and now it is working great. I will only upgrade to Red Hat newer version if one of you convinces me why that would be a good idea to disturb a system that is working well. Thanks again everyone. Now to learn how to be effective in using/operating LinRad. Dave Schmocker KJ9I P.S. My future plan is when the SM5BSZ all-stages 144 MHz receiver is ready, I will convert rx to that full system and then use full V/H separate feeds into LinRad DSP for optimum benefit of LinRad V/H and wide-band receive capabilities. I still need to design the complex T/R relay scheme for this.
