Just wanted to voice the opposite opinion. You will eventually NEED to go to a direct sampling architecture (Orion 4), although you might get away with one legacy dsp IF rig (Orion 3). Barry N1EU
Believe it or not, I had an Orion II, K3s, Flex 6500 and ANAN-100D on my table together for about a year. They're all amazing rigs. I threw the toughest condx at each of them and they were all up to
Your original email also said "When I choose a version 2 firmware in that program, it counts line 0 of xxxx, but never progresses or does anything else." Barry N1EU
The mod is only so you can use the SWEEP function. Without the mod, you can still safely run v3 firmware, but SWEEP won't work. IMHO, the SWEEP is almost useless anyway. Barry N1EU
The HDSDR software (SDR and panadapters) has a binaural mode under Options - Output Channel Mode for RX - IF as I/Q L/R and plug your headphones into the selected Soundcard. I believe PowerSDR also h
It's important to understand that not all binaural implementations are equal in effect. They vary drastically. The binaural/spatial stereo effect is very prominent in the direct conversion designs th
Jim, could you possibly snap a photo after you mount the new speaker with a note on how the install went? Many of us could benefit from the info and I'll upload it to the TenTec wiki. Thanks & 73, Ba
I've seen the following suggested as substitutes: NTE473, 40290, PT3501, ECG473 but you need to check the specs. I do see that randl.com sells the ECGF473 for $6 Barry N1EU
I believe the problem is specific to the Acom 2000A but not 100% sure that Acom amplifier models are immune. Using a BCB high pass filter fixes the problem. It's due to low level, low frequency spurs
There are 27 Orion I firmware updates available on http://tentecwiki.org/doku.php?id=orionfw It's possible that only 13 were publically released and the others were made available to the Wiki by beta
That's good info Steve. John, you can probably use a splitter cable, 1/8in stereo jack with two RCA mono plugs coming out of it and figure out which of the two to plug into the Omni. Here it is for u
The first IF of the Delta II is 45MHz. The tap is easy because there's a connecting cable carrying the 45MHz signal between 1st mixer board and the 2nd mixer board (connector 76). You would tap it ri
