S meter stays just above noise level, so it remains usable for most signals. If the external noise activates AGC, then it is the external noise actually determining usable sensitivity, not RX gain or
No, I've never recommended such a thing, you misread it. In my text 12 dB refers to the difference between external noise level and RX internal noise level. The adjustment is performed by using contr
Not true. It is easy to verify that PBT functions correctly with both filters at 2400 Hz, or any other value. No, Orion normally uses only the central part of roofing filter's BW in order to prevent
I'd say it is quite good. Only the flat [central] part of roofing filter's passband passes through the DSP filter and DSP filter's passband flatness is mostly preserved. Also, group delay variation o
... Hi Bob, several months (and revisions) earlier, I performed detailed measurements and found that quality of transmitted CW greatly varied with code speed, time between characters/words and especi
Unfortunately, Orion's TX seems to operate "full QSK" all the time. There is a CW PTT input now, but TT choose not to use it to prepare TX for transmission. PTT is only used for external amp control.
Orion's ADC chip has S/(N+D) specification of 84 dB minimum, 90 dB "typical". This specification applies to manufacturer's test circuit only, and one has to consider Orion's actual circuit. Looks li
Looks like SDR has more marketing than contesting advantages :-) Also enables manufacturers to save a couple of bucks, while simultaneously claiming technological advance. 73, Sinisa YT1NT, VA3TTN
Reality is that FT-1000x was released with a number of problems two orders of magnitude smaller than Orion's. I'd put aside the possibility of adding any new features to Orion at least until it begin
Well, I have one with most of the options. It did cost me ~$6600 to arrive here. Describing its operation with the supplied firmware as "unfinished" is actually a very mild way of putting it. 73, Sin
