Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
Lu, if you have access to an SDR receiver that can record it's output on a PC, it might be easier that using a noise source. When comparing several microphones and headsets on my K3, I used a Perseus SDR to play back the results for A/B/C/D comparison in order to pick the best equaliser/mic combination. The saved files from the Perseus were labelled to match the microphone and can be played back very easily, in addition, recording a wide chunk of frequency means the bandwidth can easily be checked if that might be an issue. 73 Dave __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
Pardon me, but I have read a lot of the traffic on this topic, and some very good ideas have been considered. Recorded audio into the mic jack or a sound source as in a 'pink' noise, or ''white' noise allows the radio to be adjusted. I have a K3, so I can use it with the P3 to analyze the audio of my other radio(s) while transmitting into a 'dummy' load. But, none of these account for the difference in mics. A station with a dozen radios and a dozen mic is still going to show differences in transmitted audio due to different mics and mic usage/voices. I'm glad I don't have to do this! ...bill nr4c On Tue, 25 Oct 2011 13:09:47 +, Dave Johnson wrote: Lu, if you have access to an SDR receiver that can record it's output on a PC, it might be easier that using a noise source.

Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
Hi Don: Thanks for the response. Maybe Im not clear regarding what Im trying to do. I have a dozen TenTec Orion 1's at a multi multi operation I play at. Im tasked with standardizing the audio parameters for this operation in regards to compression and frequency response before CQ WW SSB. We want to make sure that all the rigs sound as good as they can sound and have consistent levels. People play with these radios over the ensuing months, so they are usually diddled to death by the time I get there. I have done this in the past by ear. That is, I have plugged a given rig into a dummy load and diddled with the audio settings until I got it to sound right. I wrote down all the settings and went to another radio. I set that radio on a dummy load and input all the settings I wrote down on the first radio. I used the same microphone, the same audio path and made sure the radios were at the same software revision. Lo and behold, the second radio sounds different than the first with exactly the same numbers in the software! I have found in practice that no two Orions sound the same, using exactly the same numbers and exactly the same microphone and exactly the same voice (mine). What I want to do is inject pink noise from a Flash Memory WAV player that has a track from the NAB Audio Reference disk. I have the WAV player set to loop the file forever. Feeding it through a Radio Design Labs line level to mic level amplifier block, the level coming out is 0 VU mic level at a nominal 600 ohms impedance. I want to feed this into the mic input of the Transceiver under Test and, with a spectrum analyser looking at the output of the audio monitor circuit (yes, not ideal, but it gets me in the ballpark) see where Im at. I trust my ears, but it would be nice to be able to see the waveform on the SA. Knowing where I am at, I can then adjust the rig's settings and even pre-distort the audio input from external processing (several transceivers are driven through W2IHY processors) to optimize drive, punch and inteligibility. As I said, I have done this by ear in the past. But now I have a P3. I can do exactly the same thing on my personal K3 by disconnecting the serial connection. I can then see the output of the rig in the P3 via IF leakage, and I was able to look at what pink noise looks like at my personal station and the effect of applying EQ to the pink noise VISUALLY on the P3. I could do what I have to do faster on the Orions if I could SEE the waveforms. It would save me time I can use otherwise at this station. What I would like to know is if the P3 can, using any IF leakage from the Orion's IF out, do the same thing as I can do on my K3. Im not looking for any laboratory grade results here, Im just looking for a ballpark image of the modulation envelope that includes frequency domain information so I can judge the flatness (or lack thereof) of the audio frequency response of a given Orion rig. This way, I can twiddle the knobs and match the rigs as closely as possible to a consistent starting point since the same identical numbers dont seem to have indentical results across Orions as they do on K3's. If the numbers gave repeatable results across several Orions, I wouldnt have to do this! I would just input the numbers into all the rigs and have a consistent starting point for tweaking. I want to use what I have on hand, I dont want to go out and spend money or time building things. If I was still at my old TV station, I would borrow the Tek Spectrum Analyser at the transmitter, or the Anchor audio analyser at the studio and be done with it, but I dont work there anymore and dont have access to these tools, so I wanted to use what I had on hand. Guess I will just have to try it and see if it works! Or maybe I will look on the web for a freeware or shareware audio baseband spectrum analyser which runs on a PC laptop which I can then plug into the headphone output of a given Orion and observe the waveform there. I was just curious if someone had used the P3 for something like this in the past. -lu-w4lt- Message: 17 Date: Sun, 23 Oct 2011 23:40:35 -0400 From: Don Wilhelm w3...@embarqmail.com Subject: Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?

Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
If you protect the P3 input with some back to back diodes, put a piece of wire on the IF input, dial up the P3 IF to the the freq you wish to listen to, and the P3 will show you the received signal. I think the caveat is to protect the input to the P3 or you will burn it up.. Merv K9FD/KH6 Hi Don: Thanks for the response. Maybe Im not clear regarding what Im trying to do.

Re: [Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
Hi Lu, Why not just tune the K3 to the RF output frequency of the Orion? The K3's IF output signal is picked off before the crystal filters, so the P3 shows the actual unfiltered signal received at the K3 antenna connector.

[Elecraft] P3: Can the Panadapter be used with a Ten Tec Orion 1?
Hi all: I realize that the P3 can be set to function with various transceivers, but can it be used with an Orion 1 (the original model, not the current model)? Im not really interested in using the Panadapter for monitoring On Air received signals (although that might be nice if it worked well for that purpose as well because the scope in the Orion, well, sucks!). No, what I want to do with my P3 is use it as a local spectrun analyser scope to set audio frequency response and equalization for transmission. Transmitting into a dummy load and turning monitor on, I can hear the monitor output of the Orion, but it would be nice to also SEE it as well to better and more accurately shape the signal. Yes its better to do it with another receiver, but time is of the essence in this environment. Lacking a audio spectrum analyser, but having a P3, I thought I could put it to good use next weekend for setting up consistent audio levels and processing in this Ten Tec environment. I have 12 Orion 1 transceivers to match and not much time to do it, so it would be a helpful tool to have! Thanks in advance.
