I forgot to mark the housing position before separating the upper/lower azmith assemblies. I think I know where it was pointed, but how can I tell where it should be aligned? Is this really a non issue? It really is an issue as to how it goes back together because of the way the AZ and EL motors are mounted on the L-bracket. You can tell which way the top should go on by connecting the motor and the pot to the controller box and stopping it at zero (N). Then install the case so that the limit dog is exactly halfway between the limit switches. That should have the cross boom pointing east and west and the antennas pointing north. 73, Tom ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Fw: Appreciate Assistance in Tuning MBM88/70cmAntenna
I forgot to mention that the MBM88 was also referenced as a Jaybeam. It was manufactured by Jaybeam Limited, ,Northampton, England and was recognized for its excellent performance. From: Farrell Winder Sent: Thursday, August 02, 2012 10:23 AM To: AMSAT Subject: Appreciate Assistance in Tuning MBM88/70cmAntenna I have an MBM88/70cm antenna that was very popular several years ago. Is anyone currently using it on satellite reception? I want to tune it for 439.25 MHz. Does anyone have a procedure for tuning to reduce SWR ? Specifically can the wing nuts on the reflector and director be loosened to slightly move the element position to optimize SWR? Anyone with experience of coax length that might effect SWR?

[amsat-bb] MATLAB serial comms?
Does anyone know how to send SERIAL Characters from MATLAB? The catch is, we are trying to send BYTES above 127 (Extended ASCII) and the usual %c formatter while using CHAR(133) for example, does not actually send the byte "133". Relevance is: Students working on an APRS satellite project. I can do it EASILY from all kinds of other devices, but the professor insists on using MATLAB syntax.

[amsat-bb] Re: FT-726R tuning problems.
Hi, Do you have the "sat" option? Need more info. I use my 726 often and have no real trouble apart from rudimentary computer control. It's still a good radio though.
