Greetings Hermes Group,
Well I have a Hermes Lite 2 with no TX power all. At this time using Thetis 2.10.35  then switch to SparkSDR. I went threw the complete trouble shooting Steve had posted. All  good till I got to the DB3 test point and found no signal at DB9 3&4. Yes the transmitter is keying he leds on on the front panel  tx&run  are on. 
 When running SparkSDR I noitce the swr is jumping
all over the place, the current is 105 ma. and of coarse the fwd pwr is 0, the temp is slowy
raising up .I recheck all my test gear all good. RX works great .
I'm open for  suggestion .
Peace Allen

Hi Allen,

I don't follow what you are saying about DB9. Are you measuring at DB3 or DB9? With an oscilloscope and CW TX on 80M, what is the peak to peak voltage you see on DB3 pin 4 to ground, and pin 3 to ground? Is there any signal? Does applying downward finger pressure on U7 cause signal to be seen?

Also, for warranty purposes and as requested on the wiki repair page, what was the ship date of your HL2 from Makerfabs? Did you make any modifications to the HL2 PCB?

I only do a few domestic warranty repairs. If this falls outside of a warranty repair, you may find help on this list.

Hi Allen,

Please do not post personal contact information on a public group. I deleted your posts for this reason.

I am no longer doing any repairs except for a few domestic warranty repairs. You may find someone else in this group willing to help.

Hi All,

Please see the wiki help:

Search this list via the web interface for similar problems:

Track down YouTube videos and other Hermes-Lite 2 guides via Google or the wiki above.

Try several different software programs to eliminate possible bad settings in one software program.
