Initially it looked like object 2019-071G was HuskySat-1, but our friends at the 18th Space Control Squadron published data on additional objects in recent days, and there is considerable evidence suggesting that HuskySat-1 is actually one of those instead.
Element sets for objects 2019-071H and 2019-071J are now distributed in nasabare.txt as candidates for the "Real HuskySat-1".

With new TLEs published new doppler measurements now show that HuskySat 1 is actually object 45132 (2019-071J). Downlink frequency: 435.7997 MHz.

As time has gone by, the 071G TLE was requiring more manual Doppler correction here, despite automatic Doppler Correction from SatPC32. I had to adjust it manually another +/- 400 Hz through the course of an orbit.
Today after changing to 071J, the fit is MUCH better, only +/- 100 Hz manual correction needed over the pass at ~19:10Z.
Getting closer for sure!

It looks like that OBJECT J (COSPAR ID 20071J) is moved from NORAD ID 45132 to 45119. OBJECT J with NORAD ID 45132 hasn't any TLE update for the last couple of days, in contrast the new one (45119) gets updated.
Still the old TLE from 45132 describe well the orbit of HuskySat-1 but it looks like that soon will not.

Freddy,
Yes, it looks like they are changing the catalog number of object J. 45119 almost perfectly overlays the 45132 Keps, and they are much more recent. Testing today has given "hands off" tuning on multiple passes.

It is a weird situation ... even orbital guru T.S. Kelso scratching his head over it. See comments on his Twitter account.
