[linrad] MAP65 compiling
Dear Joe, I have just a couple of questions about current MAP65 compiling status: - Is MAP65 currently only working on Windows platform? - Did you cross compile MAP65.EXE under Linux or directly on Win? - What's your plan for a (beta) release of source code to play with? After some work, with help from Roger W3SZ I have been successful to compile WSJT598 on Ubuntu 7.10 and I would like to do the same for MAP65, since I am planning to make some experiments on 6m JT65a. Just for your knowledge, next month the Ciao Radio H102 direct sampling receiver with dual parallel input should be available, and I am curious to see if it can be used for dual polarization EME work.

[linrad] MAP65 and 50 MHz
Hi all, I am preparing the gear to try MAP65 on the ARRL EME contest on 50 MHz. Checking the software I found that current version of MAP65 only supports mode JT65b (in use on 2m) and not JT65a, used on 6m and HF. Joe, is there any chance to enable also this mode?

[linrad] Re: Linrad-02.39 and Linrad-MAP65
Hi Roger, I have been playing with Linrad and MAP65 and have made several EME contacts this way. It is a lot of fun, and truly amazing. MAP65 finds stations that I do not see on the waterfall with my usual [aggressive] parameters! This worries me a lot. I know you mentioned this before and I have been worried ever since. It would be interesting to have a file that contains an example. It should last at least 4 minutes so one can see the 1 minute on/off pattern of JT65 to distinguish from all the spurs that are likely to be present. I would like to be able to specify which of the two network cards in my Linrad computer is the one that Linrad uses to send the data to the MAP65 computer, as that way I will not tie up my network by blasting it with the multicast and won't have to disconnect this computer from the network each time I want to use Linrad and MAP65. Is doing this as simple as specifying sin_addr [which I found in network.c} somewhere? I really do not know, but I have a feeling that this has to be done outside Linrad with a network tool of some kind. I hope someone else will know better:-) 73 Leif / SM5BSZ # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] Re: Linrad-02.39 and Linrad-MAP65
Hi Leif, I would not worry. I assume that it means that I haven't set my parameters optimally, or that I have so many birdies that they are hiding under a birdie or mistaken for one. I just thought it was 'cool'; kind of like finding a station when tuning an old fashioned radio with knobs on a band that you thought was 'dead' ;) I have had such good experience with Linrad that I have never sat down to learn the theory and optimize things for my particular setting. The 'defaults' do very well for me, and I just do a little tweaking without as much thought as I should put into things. SO if you must worry, worry about my IQ deficiency or my curiosity deficiency and not a Linrad deficiency ;) OK on the second question. I thought the address of the NIC to be used was something easy to change in the Linrad code. Knowing its not, I will delve into how these things are handled by the OS and see what I can do [unless someone pipes up with the answer and saves me the trouble] ;) Thanks again for all, and 73, W3SZ Roger Rehr http://www.nitehawk.com/w3sz Quoting Leif Asbrink [EMAIL PROTECTED]: Hi Roger, I have been playing with Linrad and MAP65 and have made several EME contacts this way.

[linrad] Re: Linrad-02.39 and Linrad-MAP65
Hello all , I think that if we need LINRAD and MAP65 to gain popularity , we need some RX hardware. Something less expensive than Leif's hardware , but better than Time Machine , anybody working on this? 73 Dom # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] MAP65 v0.7 r474
To: HB9DRI, IK7EZN, W3SZ, W5UN Cc: Linrad mailing list From:K1JT Subject: MAP65 Beta Testing Date:July 5, 2007 MAP65 version 0.7, r474, is now available for download on the WSJT Home Page, http://physics.princeton.edu/pulsar/K1JT/ . The actual installation file is http://physics.princeton.edu/pulsar/K1JT/MAP65_07-474.EXE . You should first read the updated MAP65 Status Report, http://physics.princeton.edu/pulsar/K1JT/MAP65_Status.txt , and then the MAP65 Quick Start Guide, http://physics.princeton.edu/pulsar/K1JT/MAP65_Quick_Start.txt This early version of MAP65 works well. However many planned features are not yet in place, and surely there are bugs in the code. I expect that there will be frequent updates to the documentation and the program in coming days and weeks. Please report your experiences, bug reports, and wish list to the Linrad mailing list. -- 73, Joe, K1JT # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] MAP65 and Linrad Network
MAP65 Status I have now established the necessary network connection between Linrad and MAP65. So far, I have found nothing to prevent a happy marriage! MAP65 receives a full 90 kHz of xpol signal from Linrad, finds all the JT65 signals in that bandwidth, matches the linear polarization angle of each one, decodes the messages, and provides the operator with a band map showing callsigns, operating frequencies, polarization angles, and message contents over the past 15 minutes or so. The program provides a full-width waterfall display and another one zoomed in on the frequency of the station currently being worked. Questions about Linrad's TIMF2 Multicast Data - Header information accompanying Linrad's multicast TIMF2 data includes two single-byte parameters, userx_no and passband_direction, about which I have questions. I understand that userx_no should correspond to the number of RF channels, with negative sign indicating floating format. I would have expected the value -4 for my system using xpol antennas and the WSE converters (I and Q for each of two polarizations), but in fact I see -2. Is this as it should be? Similarly, I would have expected passband_direction=1 as I have no LO's on the high side and the spectrum is not inverted. However, Linrad sends passband_direction=-1. Is this correct? Linrad FFT Versions --- I have been using FFT Version 0 for the first forward, first backward, and second forward FFTs. This produces floating-point TIMF2 data on the multicast network. To save on memory usage in MAP65 it may be desirable to use 16-bit data for TIMF2. I have effected this by setting first forward FFT to version 5, first backward FFT to version 1, and second forward FFT to version 2. Are these good choices? Is there any downside to their use that I might not have thought about? Also, with these settings I notice that the signal in the high resolution graph (red dB lines) is higher than it was with FFT versions 0. Should I adjust some other parameter to bring this level down be several dB? MAP65 with Windows, Linux, FreeBSD, Winrad, SDRxxx ... ? Like WSJT, MAP65 runs on both Windows and Linux. (It should also run on FreeBSD and Macintosh, but I can't test those here.) In my station I will probably run Linrad under Linux and MAP65 on Windows, on a second computer. In response to questions I have been getting: MAP65 could run with Winrad or with various SDR's if their software is modified to provide the necessary multicasting capability. In itself, this would not be too difficult. However, one of the most important MAP65 features is its automatic Rx-polarization-matching capability. That requires a receiver with full xpol processing, which (as far as I know) is not now provided by Winrad, SDR-1000, SDR-14, or SDR-IQ. -- 73, Joe, K1JT # This message is sent to you because you are subscribed to the mailing list linrad@antennspecialisten.se.

[linrad] MAP65 status report
Dear EME Friends, A month ago I mentioned here a piece of SDR software that I have been working on, tentatively called MAP65. Many people have written to ask for more details. I have consequently placed a status report and a MAP65 screen shot on the WSJT web site. Links to them are given below. Very briefly: MAP65 is the back end of a a wideband receiver optimized for JT65 signals. It works together with Linrad and suitable RF hardware to provide automatic polarization-matched reception of all detectable JT65 signals in a 90 kHz passband, in real time. The program runs under both Windows and Linux. In the future it will probably work with Winrad, as well as Linrad. The present state of MAP65 can be judged from the screen shot, which was produced by processing 10 minutes of data recorded on November 11, during the second weekend of the ARRL EME contest. In those 10 minutes, MAP65 decodes nearly 50 callsigns of EME stations operating between 144.100 and 144.160. My EME antenna at the time was a pair of 2MXP20 yagis. MAP65 has not yet been used on the air. My EME antenna was taken down just after the 2006 ARRL contest, and its replacement will not be erected until warmer weather arrives. The MAP65 Status Report and Screen Shot can be found at: http://pulsar.princeton.edu/~joe/K1JT/MAP65_Status.txt http://pulsar.princeton.edu/~joe/K1JT/MAP65_1.JPG Like WSJT, MAP65 will be Open Source software. I hope that these small tidbits of information will entice some others to participate in the program's development.
