Using a terminal program such as putty, teraterm or real term open the programming com port at 9600, N, 8, 1 and no handshaking Turn on the station and you should see a few lines as it boots up and

So what is the next best move. Repeater will not read or write. You guys guys seem to have this issue before and looking for a little more guidance

Still need these? I recently acquired a Decibel products duplexer in this range that won't tune high enough for 440mhz. Jeremy K1LFK

I have several RBI-1's I'm just planning to list on eBay (sold two, already and have two left.) Larry

The FTM-400 series similar to what's in the DR-2X receives 108 through 1GHz and no tight helical filters like some of the older rigs.

I'm partial to low-in, high out (Repeater TX high, RX low in other words) as it puts your input further away from higher-power users in the lower 450MHz spectrum (remember, 450-455 is an *output* band

Next to my can of freeze spray, my hot-air rework station and heat gun have been valuable tools in ruling out temperature sensitive components/junctions. Next investment is a small IR camera for

I have to admit I hadn't thought of that!. Well, tomorrow it should be in the 30's up there so perfect! Ken

Have you considered bringing a heat gun to the site on a cold day? Simple approach yet may reveal your culprate pretty quickly - at least rules out temperature issues with your indoor

On review of the play this may be related to cold and or cracked solder joints on the capacitors in the PA: https://youtube.com/shorts/tPj07DoxBOA?si=_V_bICQCBCSLbR_J The temperature change is

Your spectrum images show almost exactly what I was saying. When I said "not a huge difference", I meant comparing the duplexer attenuation by itself to what the bandpass filter was by itself at 5 mhz

It doesn't appear to be wind related. It can be windy as heck up there and absolutely no noise of any type. It can be calm (as it was when I recorded that) and it makes noise. Ken

Thanks Matt We'll double check that when we're up there tomorrow but this particular antenna is one of the newer styles where they use 2 bolts to secure the antenna to the mounting sleeve as opposed

Sounds to me like an intermittent in part of the antenna moving somewhat in the wind, because of the cracklies gaps say when the wind up at the tower subsides a for a second. John
