The PGA-103 is nice utility amp but too much gain for uBitx.? It needs more like a grounded gate Jfet (10db is enough).? A wideband high gain without band limiting(tuned) will cause all sorts of

I use the best tool I have for spotting 10 and 6M activity. My radios.? There is always one on 10M and 6M turned on. The advantage of building monoband radios they are opimized for the band and? I

Assuming there is nothing wrong with the rigs the excess current the supply can put out will not be used and you are safe. It is just like in your house, the AC outlet can put out lots of current,but

Bill, that is a great answer! Al

I have a tendency to over fuse. One on the hot one on the ground. Will the BITX40 be happy with 13.8 volts?

The filter on my ubitx seems narrow. By feeding in a 1000 hz signal into the mic input and measuring the power output and then going up and down in the audio frequency I seem to have about a 1650 hz

Yeah, and now we're also getting Aurora on top of it. Now that's why 10 and 6 are called the "magic bands"! 73 Allard PE1NWL

Hi George, If you don't know (remember) and you ask a question then it isn't a dumb question :) Your power supply does not 'force' 20 amps. It tries to 'force' 13.8 volts and it will until it gets to

Should work fine. I'd add a 3 Amp fuse inline on the +12v from power supply? to Bitx40 to keep explosions down to a minimum. Jerry

Your powersupply will only supply the amount of current the radio needs. So for your powersupply , you will have no problem and it will only be loaded with a few amps , depending if your in rx or tx

I have a 13.8 volt 20 amp supply I use on my 2 meter rigs. It has multiple connections for power out. Will my BITX40 only use the amps it needs or am I going to blow it up? I am sorry if this is a

I have several mics with goosenecks. On all of them the shield is connected to the mic base body. Since the gooseneck is metal like the base, it's connected to the shield as well. That said, on at

I don't think it is strictly necessary

I put +5 on the unused pin.? If you want to put a preamp or speech processor in a mic the power is there if needed. -- Lee - N9LO?"I Void Warranties"

Thank you all.?? I like Jazz.? On my mp3 player I have a 3 piece band.? Drums, bass, and piano.? The drummer is playing on the snare with brushes.? I plug my SSB-Mite in it and it sounds good.?

The 4sqrp filter is probably an audio filter like the 200hz very nice cw filter from them I assembled some time ago. The one in the Ubitx is the several poles 2nd IF crystal filter.

Exactly, it's its stock crystal filter at the second IF. Depending on how the BFO was set. If the carrier is closer to the filter bandwidth you will have more basses and less high and less sideband
