| + | **From the Ten Tec Reflector November 13, 1998** | ||
| + | |||
| + | I have a Delta II which I purchased to use as radio2 for | ||
| + | contestng. | ||
| + | |||
| + | I purchased the Model 305 for the RS232 level conversion that is | ||
| + | necessary for computer control of the Delta II. You could just | ||
| + | as well build your own. My 1995 ARRL Handbook for Radio Amateurs | ||
| + | has the schematic and writeup on an RS232 level converter using | ||
| + | the same chip as the 305. | ||
| + | |||
| + | The baud rate is fixed at 1200 baud. | ||
| + | |||
| + | You may very likely need to know the 'receiver address'. Mine is | ||
| + | 64. You can find and set your's by pressing the "F" button, the | ||
| + | <MODE button (That's the LEFT ARROW-MODE button). On the LCD | ||
| + | display you will see HEX numbers (mine says EC.006.4) in place of | ||
| + | the frequency. The 6.4 is the 64 receiver address for my radio. | ||
| + | You can change the number by pressing the Up or Down arrow | ||
| + | buttons. (I'm telling you this in detail because I had to call | ||
| + | Ten-Tec service department to find out how to do this; it wasn't | ||
| + | in the manual.). | ||
| + | |||
| + | I found a problem with the computer/radio system that I am trying | ||
| + | to work through. The computer software polls the radio for the | ||
| + | frequency once a second. I have had to turn off the polling | ||
| + | while the radio is transmitting, otherwise the CW characters get | ||
| + | all chopped up and are unreadable. With the polling off while | ||
| + | transmitting, only the first character is chopped (truncated?), | ||
| + | the rest of the CW is normal CW. There are a couple of other | ||
| + | software commands I found in the logging program command list | ||
| + | that I am going to try this weekend and see if that will resolve | ||
| + | the first character chopping problem. | ||
| + | |||
| + | My radio1 is an Omni VI+ and I've had no similar problems with | ||
| + | it's computer control (same computer and same software). So, I | ||
| + | don't know if the problems I am having with the Delta II are | ||
| + | endemic to the radio or if it's just a problem with my radio. | ||
| + | YMMV. | ||
| + | |||
| + | 73 and good luck, | ||
