I have the same problem with DXBase and have tried four different serial cards to try to accommodate the flaky serial port routines provided with DXBase 3.0 for HF radio control. I have purchased a buffered 16550 type serial card in desparation , hoping it will be the "workaround" needed. This problem exists in at least DXBase versions 2, 3 and 4. I have NO other programs that have any serial port problems with my hardware configuration (which is standard). My Hardware: 486dx2 (33 MHz), COM1 / COM2 / LPT1 used with standard addresses and IRQ, 200 MB IDE Hard Drive and VGA video card; HF Radio Kenwood TS950SD with IF232 interface box. IF YOU CHOOSE TO RESPOND TO THIS SURVEY, PLEASE DESCRIBE YOUR HARDWARE (INCLUDING HF RIG INTERFACE) EVEN IF YOU DON'T HAVE THIS PROBLEM. K5ESW's DXBase SURVEY / Problem Description follows. **************************************************************** From: K5ESW Date: 6-Nov 1453Z Subj: DXbase & HF Rig Problem Survey I use DXbase 3.0 and have been happy with it except for one problem. When I first start DXbase I often get a message "Unable to link to radio". After this message the only way to get DXbase to talk to the HF rig interface is to go to the QSO LOG menu, choose USER SETUP, choose USER PROGRAM OPTIONS, and then hit Escape. This causes DXbase to reinitialize communications with the HF rig. I usually have to repeat the entire sequence several times before the rig interface is successfully established. If I do not notice the "Unable to Link to radio" message I sometimes log a QSO on the wrong band because DXbase will use the last band logged if the HF radio link is down. I called Dean, W8ZF, and asked him about the problem. He said this was uncommon and suggested it might be due to an interrupt conflict. I have looked my system over and cannot find an interrupt problem. My hope was Dean would tell me they had improved the error recovery in DXbase 4.0, but he said there have been no changes in this area. I would like DXbase to retry initialization with the HF rig after an error. This would save me from going thru the awkward manual method mentioned above. You can reproduce the above failure my simply leaving the radio off at the time you start DXbase. The user's manual says that my situation is expected but rare. Page 104 says,"4. Timing was out of sync at the instant initialization was attempted. This situation is classified as normal, but it should rarely happen." My failure is certainly not rare. Are any other users experiencing this failure? Send me your comments and I will post a summary message. Also how many of you are using DXbase but DO NOT use HF rig control at all ? Maybe the DXbase developers think the problem is rare because most of the users don't use the HF radio control features and therefore never experience the problem. I checked with the developer of Logic4 to see how they handle the radio interface. He said they do not try to remain in sync with the HF rig. They initialize the interface every time Logic4 needs to communicate with the HF rig. I ordered a demo disk to try it out. My particular setup here is an ICOM 765 with the rig interface on COM3 using IRQ 5 (normally reserved for LPT2). My TNC is a PK-232 connected to COM2 using IRQ 3. I have a data/fax modem on COM1 using IRQ 4. I run Windows 3.1 and use DXbase in a DOS window. 73 Paul K5ESW Posted by : Mike Wood Internet: mikewood@mercury.interpath.net The Signal Group Amateur Radio: NT4O P.O.

You can call 619-465-exam for a recording on where the site is located. However, they usually like 10 days advance notice. It can get crowded, and some sites do not take walkins. The SANDARC VE prg gives there exams on Sat mornings, and the SANDARC group does not charge!! That is where the proceeds go from our convention that is held here about every 4 years.

Earlier this year I passed the five written and one of the code tests, as well as taking the other two code tests which I didn't pass, all in one session and the total time was two and a half hours. That's including the time for the VE's to grade my exams, along with all the exams of the other candidates, as well as waiting for all the forms to be filled out and signed. Four months later, I passed 1c to get my Extra. :-) -Brian ------------------------------ Date: 8 Nov 94 19:19:23 GMT From: joopv@etprs.phys.tue.nl () Subject: PK96 & IC-281H Darren Leno <Darren.Leno@f747.n115.z1.fidonet.org> writes: >I'm having trouble getting my Icom IC-281H and AEA PK-96 to work at 9600 baud packet.

I have done test with the IC481H, the 430 MHz version. I found it to be totally unacceptable for 9600bd : - tx-rx turnaround times are more than 100ms - tx is a VCO modulated PLL transmitter. There is a big peak in the modulation response around 41 Hz. However, receiving was ok. So i guess our tests are'nt compatible.. 73 Joop ------------------------------ Date: 7 Nov 1994 16:20:33 -0500 From: dtiller@rmc.edu (David Tiller) Subject: Routing Coax into house? Robert J.

Some also make a false window sill, that is split and drilled >for the cables. For apartment or other installations where you can't/don't want to drill through walls or windows, you can make a simple feedthrough using two pieces of lumber, which you then close the window on, keeping drafts out. Sandwidth the two pieces of lumber together with C clamps, and then drill holes of the appropriate diameters for the cables you need to pass through, with the holes centered at the junction of the two pieces of wood. Sample: | | | SLIDING WINDOW | |_____________________| |_______/\_____/\_____| <- top piece of wood |_______\/_____\/_____| <- bottom piece of wood (The diamond-shape holes are supposed to be circles, but as we all know, programmer's shouldn't attempt to do art.) Drill more holes than you need initially to save labor later, and plug the unused holes with pieces of rag or dowels or corks from wine bottles. As you need to add/remove cables, you lift up the window, take off the top piece of wood, and lay down the new cable, and reassemble. Doing it this way instead of drilling holes in a single piece of wood allows you to get cables in/out while the connectors are attached. If you pick two pieces of wood that are narrow enough, the window will still shut enough so that you probably won't have to do anything special to keep drafts from coming in where the top half and the bottom half of the window meet (where the latch is). For drilling, the dimensions of the common sizes of cables are listed below: RG-58 size - .195" (use 13/64" or 7/32" bit) RG-8X/RG-59 - .242" (use 1/4" or 9/32" bit) RG8 - .405" (use 13/32" or 7/16" bit) (The smaller of the two bit sizes listed above should make a tight fit to keep the cables from pulling in/out). --- Jeff -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Jeff DePolo WN3A Twisted Pair: H:(215) 337-7383 W:387-3059 x300 depolo@eniac.seas.upenn.edu RF: 443.800+ 442.400+ 442.200+ MHz PL 3B Claim to Fame: I got the first speeding ticket on the information superhighway ------------------------------ Date: 8 Nov 1994 14:48:46 GMT From: galen@picea.CNR.ColoState.EDU (Galen Watts) Subject: Uniden HR-2600 10 meter rig/ Anybody got the Chipswitch?
