My RiserBond 1270 TDR came back from DigiTrace repaired and freshly calibrated. (DigiTrace is at http://www.digitrace.com/ )
Great people to work with and excellent turn-around.
I put the returned TDR to work right away at both my island QTH and Tom K0TTC’s island home station.
A great device to have available, though not certain I could recommend every ham have one. With three stations and lots of ham friends who have opportunities to explore with a TDR, I’ve found having one useful. If I had one feedline to inspect it would be silly to have this gear around.
In one recent inspection it found a pulled coax that didn’t test very well. I am thinking that one of the ends needs rework. Swapping to feedline pull #2 was the short term solution and put the station effectiveness back to norms.
I do not believe my RiserBond 1270a was “officially” calibrated for a very long time, even when I acquired it in 2006.
So it is wonderful to put any worries about being out of spec aside as well as the return-to-duty service that was absolutely needed.
As the repairs and calibration process use several hours of bench time, the costs reflect that service investment.
