I will start out by saying this is the second gm300 to do this to me. I use it as a repeater receiver. Does very well for what it is. The unfiltered rx audio from the gm300 feeds a masters SC50 micor

Thanks, Mike, I found that you can never have to many fans. Chad Nelson WI9HF/WRPL979 Janesville Wisconsin 608-754-8671 Send from my spectrum iPhone 16.

Here’s the last one I ordered. And these guys ship quick too! https://www.coolerguys.com/products/panaflo-nmb-80x25mm-high-speed-fan-hydro-bearing-3-pin-fba08a12h-1bx?_pos=1&_sid=90caa47d4&_ss=r

We have been having an extra tough time getting the brushless fan noise on a Henry amp out of a linked repeater audio line. Tried more and more, now up to 4 automotive noise filters in series, and

Why don't you just bypass the switch, like a non switchable type. Those switches do go bad in time, and let the outlet circuit breaker trip if there is a short. Charles Adams Industrial

Hi, me again! Lol. Does anyone have a power strip that is 19 inch rackmount with about 8 to 10 outlets which is AC with surge protector? I have one but it came with the rack that I bought in the

I'm trying to run this thing in my battery backup system as well so running it on an actual power supply wouldn't work all that well unless the power supply is powered by the battery. And on another

I found on mine running it on irlp or allstar, had to run a fan on both heat sinks and cut power back to about ten watts. Cost me a p a replacement to learn that lesson. Butch

The other thing I've tried, and that is if the noise is on the dc line is running the fan on a separate small 110 v 12 vold dc supply. However, Get the ones that still use an actual transformer. I

I have the same repeater. Great little machine! I use an external power supply to reduce heat inside the cabinet, and can take with me for field expedient repeater Benjamin,

Iirc some were...it could be the 723 regulator going bad or a cap dying...if that's the case, replace the regulating IC usually a 723 and check the pass xstr to see if it's dying...you should see 18

I find that grounding plays a role in DC fan noise suppression; try running the filtered fan power wires straight to the power supply. Bob NO6B

Ron, Some HTs will not go much past their designed range as the VCO, transmitter, and receive filters bandwidth is only so wide. Once programmed, you'll need to run the alignment section of the

wow, mine must be an old one, has a pass transister regulated supply. Butch Bussen WA0VJR butchb@... irlp 7135 allstar 56023 echolink 790800

UHF What is new price on them? Roger

At least 1500 if not more. Especially since they are still in production and they're not going anywhere anytime soon. Try 80% of the new price, that's what I usually use. What

You could try about a 10 ohm resistor, with a >2000 uf cap on both sides to ground (A pi network). Better yet, use a toroid instead of a resistor with a lot of windings. Good news is that the noise

What is the value on the used market for a Motorola SLR5700 repeater removed from a working trunk system in excellent condition? Only reason for change is system does not meet the needs of the user

They probably won't go. 440 is going to be pushing the upper limit, most likely.

And yes, the front end needs to be re-tuned if it's being moved more than maybe a MHz. But there's also an issue with ceramic filters in the IF on most all radios from that vintage back into the 90's.
