[Repeater-Builder] B-215G SSB Delay Adjustment
Good afternoon. Does anyone know which of the adjustment pots controls the SSB Delay in the Mirage B-215G amplifier? They are not labeled on the board, and I do have a scribble schematic that Mirage sent me, but it has not been much help. I am successfully using this amplifier on a D-Star repeater system in SSB mode (keeps the relay chirping down and handles the narrow bandwidth of the D-Star transmission quite nicely). I would like to adjust the relay lag to max to prevent it from unkeying between each transmission in a conversation, so as to preserve the actual relay. Thanks for any help! 73 Phil - AD6NH

That way you take control away from the amp and give it to the controller? Not a bad thought, but D-Star has almost no hang-time compared to an adjustable hang-time on an analog system. Therefore, by running the amp in FM mode or using the external key line, the relay would be subject to much more switching than it currently is in SSB mode with the approx 750ms delay. Sometimes, if someone is quick on the key on a reply, the amp will remain engaged. 73 Phil - AD6NH

Place a SHORTED RCA plug into the RCA jack located on the rear of the amplifier. This will cause the transmit relay to energize when the amplifier power is switched ON. I did think of that option as well, but wasn't sure if that would burn out the relay or not. I guess if it's just a magnetic field holding a switch open then there shouldn't be any problem with that. 73 Phil - AD6NH
[Repeater-Builder] SM50 Repeater Cable Problem
I tried posting this to a year-old thread, but I'm afraid it wont be seen! I'm having difficulties in that when I plug my repeater cable between my two SM50s, the transmit radio immediately goes into transmit. I am fairly certain I have everything programmed properly, with Pin 8 programmed for DPL/PL CS Detect and Active Low. I am using this cable from Ebay http://cgi.ebay.com/Delay-Repeater-Interface-for-Motorola-GM300-Radio-NEW_W0QQit\emZ150095175361QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item22f25e9ec1 and I'm wondering if it's not correct? This outfit also sells a duplex cable, but I thought that only allowed the repeater to work in both directions, not necessarily achieve what you talk about below. I'm not trying to operate dscrossband - just a simple GMRS repeater. Thanks for any possible advice! Phil - AD6NH/WQKP927

Otherwise you will need to explain 2 mobiles and a simplex repeater. The rear 16 pin connectors have some pins that are fixed in function (mic audio, PTT, Gnd) and some that are assigned via software (type of audio output, indication of valid PL/DPL/carrier detection). The switching functions must be configured to be active atthe proper level (High or Low). Both radios will need to be properly configured. The configuration of the cable must be bi-directional; it must pass the COS, PTT, and audio signals in both directions, GND is comman between both units. Without the proper equipment and software to program the radios and documentation of the radio and the cable it's going to be rather hard to get things properly set up.

I have tried every configuration two get this to work with no results. Before I condem the cable I got off ebay does anyone know of any mods or settings that need to be done to get this simplex repeater up and running. I have confirmed the radio operation itself and they are good to go. Yahoo! Groups Links
[Repeater-Builder] TLE1713A-1 at 448 MHz
I do apologize if this has been answered already (I did spend about 20 minutes going through old messages). I just received a very clean TLE1713A-1 amp, and I am intending to use it around 448 MHz for a ham repeater. Of course, I have no documentation on this unit. Applying 13 VDC to the control line, I got a little over 150W out into a 50 ohm dummy load at 448 MHz, and about 80W out at 462 MHz. My question is, do I simply need to regulate the control line voltage to get the output power down where it belongs, or is there some circuit tuning that I should do as well? If the latter, I am in need of a procedure or at least some schematics or service manual. Any help would be greatly appreciated! Thanks for your time. 73 Phil - AD6NH
