[TenTec] QSK/QRQ problem with Orion / ACOM 2000A

[n4lq]

Per TenTec...On the Omni VI+, they came out with firmware 1.03 in an 
attempt to eliminate the microCHIRP. The revision added a delay to the 
keying of the PLL's oscillator. The downside to this is that if you key 
above about 64 wpm the PLL's timing went wacko and cw was chopped and 
erratic. This is why some of us have gone back to version 1.02. With 
this version you can go up to about 70 wpm before weird things begin to 
happen. Keying sounds ok at 75 wpm but if you hold down the dit paddle 
and listen to yourself in another receiver you will hear a murmur in the 
rhythm begin to form.
The Orion had QSK in the earlier firmware versions but due to clicking 
in the sidetone and whatever else, they added a delay in later versions 
and now QSK is non-existent over about 20 WPM or so. QSK means being 
able to hear between dits and dahs. Not many rigs nowdays can do this 
without some kind of quirk, be it pops, thumps, clicks or just plain 
slowness. ICOMs can do it but not without an external keyer with added 
weight compensation. Yaesus are slow. Kenwoods seem to do better in this 
department. Kenwood has a real weight control on their internal keyers 
and good timing. I don't know how they do at 75 wpm though.
