Re: [Repeater-Builder] RE: What Have I got and can I get information about it.
Hi Eric --and the group -- I will address the amplifier first -- All I need is the schematic -- as the keying relay is inop and I need to get the circuit correct to make it whole again -- LOL! So, if you could help with that it would be great -- I have the amp working, etc -- just need to fix the keying As for the Systel -- Here are the numbers I have -- The unit is a L1574A Tx NUE6862A SP03 Rx NUE6842A I need power supply and crystal data at the very least but a manual or copy of the alignment would be helpful -- Thanks in advance -- Rick NU7Z On Thu, Dec 18, 2008 at 9:46 AM, Eric Lemmon wb6...@verizon.net wrote: Rick, Without model numbers, it is difficult to know what you have.

RE: [Repeater-Builder] RE: What Have I got and can I get information about it.
I have 3 of them, One has HT-90 crystal controlled units inside. The other 2 are GP-300 and can be programmed. It is a bit of a hassle, as I do not have whatever is the proper interface, so I took the units out and popped them into gp300 cases and programmed them, then put them back into the Systel. Works! If yours has very rectangled shaped units that are just boxes, then it is most likely HT-90 and crystal controlled. Maybe you can find crystals, not sure. But if the 2 units look like a HT out of the case with speaker hole, kind of rounded corners, then it is probably the GP300 unit and much better. Mine work great with GMRS. -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Rick Beatty Sent: Thursday, December 18, 2008 12:37 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] RE: What Have I got and can I get information about it.

Huh? Since when is a GP300 not type accepted for GMRS? News to me, but I have been wrong before.

RE: [Repeater-Builder] RE: What Have I got and can I get information about it.
You're not wrong this time. A UHF GP300 radio with the FCC ID of either ABZ99FT4010 or ABZ99FT4011 is approved for Part 95- but only for 16K0F3E emissions. GMRS yes, FRS no. Moving on to the SYSTEL question, I just discovered that the manual is still available from Motorola Parts. It is manual 6882446W01, for about $17. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Craig W Clark Sent: Thursday, December 18, 2008 11:36 AM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] RE: What Have I got and can I get information about it.

Re: [Repeater-Builder] RE: What Have I got and can I get information about it.
The question is frequency stability for fixed stations. If the unit is operated as built (minus the phone patch) vs the possible use of an external amplifier as mentioned in the original post. Just because the portable on which the unit is based is type accepted for portable use, the use of the same radio in a fixed station configuration could possibly fall under a different set of standards. Be sure to consult the appropriate sections of the current version of Part 95.
