I need to replace the reeds for my desired PL freq. The unit came supplied with two vibrasponder reeds (same PL). I want to use the card for decode as well as tx encode out. Do I also need to continue to use two vibrasponder reeds, or do I need to use one 'sponder and one 'sender reed in the two slots (sounds more logical)? 2. Which socket is the tx and which is the rx socket? ************************************************ The reed closest to the front panel on the card is the Encode The card uses 2 Vibrasponders ************************************************ 3. Does anyone have a scanned image of the PL board schematic and/or jumper listings? Unfortunately I don't have a audio&control manual around. *********************************************** Schematic is in the link above and most other information for a MSR2000 conversion *********************************************** Anyone have any experience with effect on receiver audio quality with the PL filter inline versus out of line? Reason I ask is that I originally set up the repeater with a TS64 board (which failed), and left JU1 on the audio card in place. The receiver audio has excellent freq response. I was planning on removing the JU1 once I install the OEM PL card and remove the TS64, thus inserting the PL filter in line with the rx audio feeding the controller. I'm hoping the freq response remains the same. My experience with Micor base receivers is that the PL filter changes the audio response, thus the extra cap tht is jumpered in when the filter is not present. Hence the question....
