Haha found the relay problem

Alexandra Carter
I was looking around on the net and found one anonymous page writer,
who had the same problem ,to quote them:
"  
  Here we see the next glaring mistake.  The instructions called for
relays K1-17 to be installed as one the first things on the RF board; 
I mis-read it and installed K1-7.  This became apparent when the unit
failed one of the tests.  On examining the schematic I realized it
failed to 
  actuate some of the relays because they were not installed. 
Installing them at this point was significantly harder than 
it would have been earlier (at the proper time) but not too bad.  After
that was corrected all tests passed.
"
I also read it as K1-7 lol! Time to go install more relays! This has
had me puzzled, since how could the unit use the same relays to switch
bands and the atten and preamp?
..........
OK all soldered in and retested, everything works fine! I guess those
other 10 relays really do the rig more good in it than in their storage
tube! 73 de Alex NS6Y_______________________________________________

Re: Haha found the relay problem

PAøPJE
OK Alex, I have to read more carefully too.
You said "FIRST power up" and I missed that.
In this case you still have a few parts to go....

I wonder what the "pain" is about making the probe. I suggest to just make
it by the book 'cause building on you will find it pretty useful... Btw I
use a 'scope also, and a counter. I even have a simple yet effective
spectrum/network analyzer but believe me they are not necessary to finish
the job.

73,
