You can see a CW signal on the spectrum of CW Sweeper and other CW reading programs; likewise for PSK and RTTY. But I can't ima; /archives//html/TenTec/2010-12/msg00156.html (9,152 bytes)

They are essentially the same price and seem to have similar specs. I'm a casual user, sometimes chase DX, do mostly CW; /archives//html/TenTec/2010-12/msg00157.html (12,196 bytes)

46. [TenTec] Centurion on 17 M (score: 1): Author: kf6e@mail.com; Date: Tue, 23 Nov 2010 08:01:29 -0500; I have an old Centurion amp (the beige one). It has no position for 17 meters on the band switch. Has anyone tuned one of these on 17 meters?

Frank I have the new model and it also has no band setting for 17m. It uses the 15m position. Load about 8.4 and tune about 1.6.

49. Re: [TenTec] (no subject) (score: 1): Author: kf6e@mail.com; Date: Wed, 24 Nov 2010 08:05:37 -0500; I would strongly recommend the MFJ-998, unless your antenna is very close to 1:1 SWR anyway. They rate tuners by the range of impedances they can match, and by the power they can handle. But it's "or; /archives//html/TenTec/2010-11/msg00374.html (10,843 bytes)
