Petr, Do you have the filter board plugged in when you read 5.6k ohms?
Note in the Revision D manual, the filter board is NOT plugged in when making the resistance measurements on page 45.
The filter board is not plugged in until you get to page 46. 73, Don W3FPR On 4/21/2019 5:57 PM, Petr, OK1RP/M0SIS wrote:
Hi Don and Bert, as I noticed this evening > troubleshooting nor alignment parts are not same in the different Rev. of K1 manuals. Our sick K1 is also from 2000... RF board Rev. D, 2000 so I am using the manual Revision D, Dec 1, 2000. Unfortunately when I measured the resistances on page 45 (J7, J8 test points) I found the J7 pin 6 has 5.6kOhms to GND but table on page 45 says it should be >100k. What makes me confusing is that when I opened the later manual Revision F, January 24, 2002 I found that in the same table on page 45 the value of J7 pin 6 should be 5-7kOhms which souns ok compare to my measured value 5.6kOhms... ?!
