Mine didn't have any fans and no? cases on any of these amps either but they were complete and the box was marked as working 220 MHZ ACSSB amplifiers. The amps all included the T/R switch, a low

Hi all, I recently just picked up an item from Facebook marketplace, taking the chance on it. It was a roll of unknown coax. The seller took pictures of the roll and the end of the cable. I counted

Hi Scott!? ?All the 901 stuff has been sold.? ?Thanks for asking. Craig AA6CG

I'm not reassigning the RS232 pins 2&3. Channel select uses AUXIO1 to AUXIO4, pins 20 to 23. Joe

Best of luck. tnx Mike / K5JR Alpharetta GA

Thanks for your input, however I'm looking for help programming the MTR2000 instead of a functional description. 73 -de John NI0K

The repeater certainly would pass encrypted traffic without needing to decrypt it, but I'm wondering how traffic originating from the repeater would be encrypted, say a phone patch or some sort of

Encryption only applies to terminals (portables, mobiles etc). Basic encryption is usually good enough to avoid other radios or scanners from listening in. Advanced encryption is usually for somewhat

Hi Tim as other's have said program through the Mic socket, the HD15 on the back is for a Data terminal well the UK one was .. looked after a fleet of 50 till we swapped them out for Icom :) I think

Wouldn't the repeater just pass the encrypted audio from mobiles and handhelds? I'm trying to logically think whether the repeater needs to unencrypt it to repeat it or not. In the analog world, my

Not really. The RS232 pins can't be reassigned. Ken

Very good point. I use pins on the db-25 of one of my TRK repeaters for channel steering. With the db-25 off and no steering pins grounded the repeater will fault and not key up. Joe, K1ike

These already have fans in them. Power supply too. these amps are 28v. working good so far. The way I look at it is, they are clean and they put out plenty of power. If they fail, so be it. Better

Bummer on the recycled amps! WZ5TX David “Tyler” Bufkin ________________________________ Sent: Sunday, April 6, 2025 3:05:18 PM To: [email protected] <[email protected]> Cc:

I recently programmed an SLR5700 for "channel steering". Unknown if the MTR is similar, but the SLR was *not* like the mobiles - GM300, CDM, etc. The default channel is the one where all GPIO pins

You cannot move the RS232 pins....only the aux I/Os are programmable... [email protected]> wrote:

Another caution Be sure the DB25 on the back has not had some of the rs232 pins reprogrammed to another function. If I am programming a repeater that has been programed by someone else I never use

The 8 pin is used by the mic...but the programming pin outs remain the same so either RJ45 8 pin or RJ14 6pin works.. And actually only 4 wires are used...TX data, RX data, GND and power for the
