I've been lent a T1 tuner by a local ham friend with "can you get it to work at your station?" request, following a "no trouble found" round trip to Elecraft and back late last year.
I've never used a T1 before. Station is a Kenwood TS940 set to minimum TX power (about 5 watts); antenna is a 40M full wave wire loop. Test TX frequencies are 7 MHz (expect good match) and 3.5 MHz (expect poor match that the tuner can accommodate). After reading the user manual (dated 2018), I have tried to reproduce the issue using the following steps, to no avail: 1. Tap PWR button - yellow LED flashes about 4 times. 2. While yellow LED is flashing, I can set the tuner to active/inactive mode (BYP button tapped while yellow LED flashing, yields green or yellow steady LED indication for a few seconds, and sound of relays switching with the change of setting.) 3. With the tuner in active state (step 2 above), I tried to tune for SWR: 4. Press/hold PWR button to preset for TUNE; green LED flashing for a few seconds. 5. While green LED flashing, key TX; no relay activity heard, green LED goes out. Steps 3-5 are exhibiting same result as my local friend reported - no response (relay activity or change to match between TX and Antenna) from tuner to RF from TX. The tuner's trip to Elecraft (with no trouble found) was a result of the same experience. Am I doing something wrong? Thanks! ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
