Right, well this firebird isn't even usable as an swr meter unless you put about a kilowatt into it. In the FWD, the meter won't go full scale below about 14 MHz. Vince.

Hi, gone with the go— Almost anything works receiving. More power to you for learning how to get a transmitting antenna going As you gain skills, you’ll eventually want to deal with the harmonics

Hi Tom, Building one is so easy that even *I* can do it. 73, Bill KU8H

Brand New. -- it's a second one I never built. $120 shipped Priority Mail to US only. Paypal only. Email me for Paypal address. 73, Gerry W1VE

It might be more productive if general discussion about antennas were to migrate to the antennas group <[email protected]>. That way we can focus on on-topic posts for the BITX <[email protected]>

I have an auto tuner, but what happens in the auto tuner stays in the auto tuner. So having another SWR bridge (as well as a extra manual tuner) would be nice. I would have thought that CB SWR/Power

I think that your uBitx thinks you are not calibrated. There is a function of the software which is entered when you have the encoder switch depressed during power up. Did you install capacitors on

I'm just amazed of how much priceless information I got in such a short time. Thank you for all users that had answered my questions and gave me even more than that: good advices for the future.

I've solved it! I set the calibration sound first, tuning for a near 1khz sound compared with that from my phone, then tuning the BFO to get the best match between the 1khz signal generated on my

My implementation of the filter with a single transformer. I encapsulated the transformer and the filter with heat shrink and mounted it as a single component. As before the power levels are

Total agreement here.? Amateur radio - elmering, helping each other out, and so on - there used to be a code of conduct, which is a good thing. ? I think it's still published and in the handbook,

Fabian, I am not familiar with your particular display or the CEC software. Perhaps someone else can respond here after looking at the photo of your display in your previous post, and tell you if it

Kees noted that you can't actually ground through C11 but rather R13- despite of my attempt to. :) I'll switch that up this evening. John KC9OJV

Sounds like drive issues and not enough current.? Also 3:5 Turns may be a bit steep try 3:4 or 2:3. Don't forget you have the fets standing on those long legs at at low impedance loads those legs are

Hello Jerry! Very much thanks and that is nice to hear these kind of post, i looking forward now and every post like this, which gives me good information is very nice! ok when put the I2C board away

Just one step at a time ....Did replace R97 and R98 (47 ohm) on the mosfets gates with 10K resistors ...Improved drive and output? And likely more instability.? Your getting more because the drivers

Skip, I revised the board to add a 9th relay as shown in the picture. 73 Kees K5BCQ

If you have room enough I would look to reasonably efficient wire antennas such as a G5RV, Doublet and I have seen a very cheap new small tuner from MFJ, don't remember the exact model, I think it is
