I'm tired of hearing comparisons between the K2 and the Orion. The two radios are as different as night and day. The K2 only has one receiver, NO passband tuning, much less filter choices, and a very
Who is comparing radios? What was being compared is the receiver sensitivity, noise floor and weak signal discernability. Subject came up and was being discussed. Fact is that K6SE found K2 hearing s
Yes, but Carl, you and I are not 'expert contesters', so I'm sure we are not qualified to post our personal technical opinions. Not really a big deal, I just sit on 80m and copy signals with my Orion
No elaborate test gear needed for this test. I am right now listening to an SSB signal at 24.948 mhz. On the K2, the signal is barely discernable with the preamp off. With the preamp on, the signal j
Increase in audio volume demonstrates only that the preamp has some gain, with AGC threshold not reached without preamp. Nothing more and nothing less than that. Taken alone, this says nothing about
Ok, just a quick simple test with the K2. Tuned to 28.6100 mhz with preamp off, no difference in noise with antenna connected or not. With preamp on, there is a very noticeable increase in noise with
Yuri, as an Orion owner, I interested in hearing of its virtues and flaws; however, I am not interested in your (or anybody's) invective ("Can we discuss topics rationally or is this really TT Worshi
Thanks, this clearly illustrates that K2's noise figure (preamp off) is too high for 28 MHz operation, at least for your location and antennas. How about Orion with preamp off? 73, Sinisa YT1NT, VA3T
Same test with Orion at 28.6 mhz and preamp off. Large difference in background noise with antenna connected verses not connected. The Orion has more than enough overall gain. And by the way, I am at
Yuri, with all respect, I tested and have "knowledge" of otherwise. I can't have "proof" (as you requested because that means someone else must be here) unless you are willing to accept the president
Hey Sinisa, what in the world are you trying to prove now? "Can I recommend a more repeatable noise figure test, which even doesn't require any signal on the band?" What is your point? Who among us i
Actually what Sinisa is suggesting is not just mental monkey spanking, it is a very good test. If you don't hear an increase in background noise when you connect your antenna, your receiver quite lik

I had my threshold set to 2 uv on the Orion when I did this in order to not get any AGC action with no antenna. If I put the threshold at 0.37 uv, then the DSP agc action brought up the receiver nois
Dear Rick, there is a very good technical reason for the test. Far from being a [French word], the test checks a vital condition which influences receiver's ability to receive weak signals, when the
Your tests prove that Orion has low enough internal noise to be used without preamp in most situations, unlike K2. Leaving preamp off of course ensures best possible dynamic range, which may be signi
Orion's AGC doesn't influence the signal to noise ratio significantly (which is very, veru good). It mostly influences the perceived audio volume. Therefore, the threshold value is not critical. Star
