ADDENDUM ADDITIONAL NOTES: 1) IF you have only one Antenna, after following the instructions in the manual under the section INSTALLATION AND PROGRAM CONFIGURATION, read APPENDIX D: MODIFYING THE DATABASE TO USE ONLY ONE ANTENNA. 2) If you start DX-COMM PLUS and the Drake R8 is not powered on, a "TIMEOUT" message will appear on the screen for a moment and then be erased. The purpose of this message is to indicate to the user that the DX-COMM PLUS attempted to read data from the Drake and no information appeared on the RS232 port over the prescribed read period. 3) For DX-COMM PLUS to work properly you should have no TSR (Terminate and Stay Resident) programs residing in the DOS background. DX- COMM PLUS, with the as supplied 1800 records, needs approximately 500 to 550k of free memory (as measured prior to loading the software) to run properly. The symptom of insufficient memory will be an "End-of-List" message in the Database Display Screen with no data records displayed. 4) Do not attempt to run DX-COMM PLUS by simply setting the path. Always run the program by executing it from within the directory/sub-directory in which it resides. Failure to do so may result in lost datarecords. 5) When adding records to the database, be careful not to enter "2400" in the End UTC field. Doing so confuses DX-COMM PLUS and could lock-up the program. Enter "0000" for midnight UTC. 6) If users experience a problem with the DX-COMM PLUS's Drake parameter display where the only character displayed is "1" under ANT, and the Drake R8 power is on and the correct com port has been selected as prescribed in the manual's INSTALLATION AND PROGRAM CONFIGURATION section, then read APPENDIX G: ALTERNATIVE TERMINAL HANDSHAKING MODES. After doing so perform the steps below. Step 1: Press Function 10 (F10). This will activate the Dos Shell command temporarily exiting the program to the DOS PROMPT. Step 2: At the DOS prompt type ALT_TERM and press . This will access the ALT_TERM.EXE program described in Appendix G. Step 3: Change the program from Mode 8 to Mode 9 by typing "9". Upon typing "9" within a second or less the program will accept the typed entry and will display "Time Delay=1". Step 4: Keep the "Time Delay" at 1 second by simply pressing . The program will now display "Ctrl Signal= ,DS150". Simply press . This will return the DOS PROMPT. Step 5: At the DOS prompt type EXIT and press . This will return you back within the DATABASE DISPLAY Screen of DX-COMM PLUS. If you have the com port and the other configuration parameters properly set, and the Drake R8 is on, you should see the Drake parameters displayed across the top of the screen. If they still do not display go back to Steps 1-3. Now simply press to keep the mode as "9". At, Step 4 type in a time delay of "3" seconds. Upon doing so, within a second or less the program will advance to the statement "Ctrl Signal=,DS150". Simply press and return to DX-COMM PLUS by typing EXIT at the DOS PROMPT. If the above does not work please give us a call at the telephone number listed below. CORRECTIONS TO MANUAL: 1) Correction: page 14, first full paragraph, fourth sentence. The reader is referred to "...page 13 concerning center frequency offsets..." This is incorrect. This should refer the reader to the paragraph on the same page 14 that begins, "...The next entry requires you to identify .. active broadcast frequencies..." 2) Addition: Page 17, top of page. The user is referred to Appendix E for troubleshooting In addition, the reader should refer to Appendix G and Item (2) in this Addendum. 3) Addition: Page 39 under the paragraph that addresses finding Frequency data. It is important, for example, when searching the database for the frequency 5.97500 Mhz that one type this in as < 5.975> with a space preceding the number "5". 4) Correction: Page 70, 3rd paragraph. The sentence, "The program disk is configured for mode 7", should instead read, "The program disk is configured for mode 8".
