The stock MICOR wants to see about 90 mv of audio on the mic input lead to provide 3.2 kHz of (unclipped) deviation on the carrier. A properly aligned transmitter (per the factory manual) will have the transmitter deviation control set so you CAN'T reach or exceed 5 kHz deviation, and the limiting action will start at about 3.5 kHz. Yes, you can crank up the limit pot, but since the receiver's reasonably phase-linear bandwidth is only +/- 6.0 kHz wide anyhow, it won't help much. You will have to remove much of the Tx audio stages' audio shaping circuitry, which will affect the gain and therefore the signal level required for proper deviation into the companion receiver at the other end. -- Karl Beckman, P.E. < If this English language is so > Motorola LMPS.RNSG.Analog Data < precise, why do you drive on a > (Square waves & round corners) < parkway and park on a driveway? > Any opinions expressed here do not belong to or represent Motorola Inc.

The authorized call letters are WINS and the frequency is 1010 kHz. You can calculate the wavelength by knowing that (wavelength -in meters) times (frequency -in kHz) equals 300,000. No, we don't do homework assignments while on the superhighway, we're too busy watching out for bad drivers! -- Karl Beckman, P.E. < If this English language is so > Motorola LMPS.RNSG.Analog Data < precise, why do you drive on a > (Square waves & round corners) < parkway and park on a driveway? > Any opinions expressed here do not belong to or represent Motorola Inc.

Maintenance Lab Twice I've posted querries to the Linux-Help@NEWS-DIGESTS.MIT.EDU and had only had one reply, that I solve my SCSI problems with a fan! Not having news service, I recently canceled my subscription to the Linux Help Digest, its signal to noise ratio was too low. In any case Chris, you seem to have missed my point: One does not become a ham to save money. I grant that one may have lots of fun in amateur radio for pocket change. 73, David Kelly, N4HHE dkelly@nebula.tbe.com ------------------------------ Date: 25 Jul 1994 05:39:14 -0700 From: nntp.crl.com!crl3.crl.com!not-for-mail@decwrl.dec.com Subject: Filters for TI DSP Kit To: ham-digital@ucsd.edu John Grimes (jeg@aurora.jhuapl.edu) wrote: : Greetings: : I just ordered a TI DSP eval kit (the fastest one, BTW).

If you ordered the 'C26 DSK, you can run the 'C26 software without any problem. If you ordered the 'C50 DSK, you will have to make a few changes and re-assembly any 'C26 software. Email me if you have any further questions, I have both DSK's.

Hello dear reader, Today I distributed NET_Mac2.3.43.sea.hqx... For those who don't know NET/Mac... NET/Mac is the application that supports TCP/IP over packet-radio, which means, that hamradio operators can use NET/Mac for their wireless TCP/IP network... In this version of NET/Mac I implemented the following: - Fix for mods that prompt for username and password - Some minor mods for the 'rdate' command - The NET/Mac versionnumber will now be recorded to TRACE-files - Align the output of 't s' for large-memory Macintoshes This version obsoletes all versions of info-mac/comm/radio-net-mac in the Sumex-Aim archives. The new NET/Mac has (hopefully) been uploaded to: ftp.ucsd.edu, to the directory hamradio/packet/tcpip/incoming. If it's not there then look at hamradio/packet/tcpip/mac. It may have also been uploaded to: oak.oakland.edu, to the directory pub/hamradio/mac/digital Kind regards, Adam PA2AGA (e-mail: adam@iag.tno.nl ) ( or: pa2aga@iag.tno.nl for letters only, NO BIG files here) I will be on Aruba from august 8 until august 22, so don't expect any replies during that period of time... ------------------------------ Date: Mon, 25 Jul 1994 11:46:17 GMT From: ihnp4.ucsd.edu!swrinde!gatech!news-feed-1.peachnet.edu!umn.edu!news@network.ucsd.edu Subject: Pakratt Pactor/Amtor WORDOUT To: ham-digital@ucsd.edu i have a friend with a PK900, and he is able to send back spaces, or something which deletes on my screen. tom medin N0UFM tmedin@che2.che.umn.edu ------------------------------ End of Ham-Digital Digest V94 #251 ******************************
