Hello Jonathan. It's Mike from the Early Bird Net, KC0LBY. Is the BITX Round Table or Net every Sunday Night? I just got mine put together last night and wanted to connect with other BITX40 users on

I found a small bug in Raduino v1.15 which I've just corrected and released as v1.15.1: RIT offset should only be applied during RX. However In CW mode the RIT offset was not turned off during TX (RIT

Were in the tx chain can i tap off a 20mw signal for my amplifer brick from a icom ic745

BITX QSO Night - Make that 8:00pm for the midwest. 7 was too early and too noisy. Also 7178 is better. Look for you there!

Terry The crystals do not have to be as closely matched as some might believe. Bandwidth of your filter is controlled by the C-values from crystal to ground. A bit of mismatch in crystal frequency

how much offset is needed on other Bitx40 ? when my display show 7.0320 the "real" freq is 7.0285MHz !!! I have use a Pixie with 7.030MHz X-Tal as ref.? when it comes to Birdie on 7.199 it is on

Does anyone know when the ubitx will ne sold yet

you can buy about 50 crystals for a few dollars and sort them out.

I second this. Simplify3D is fantastic.

Simplify3D? I guess. Best $149 I spent! You won't believe how fast it slices you model and puts in on the SD card! They are adding every printer model they can find. You basically get a license for 2

First put the scope with (AC coupling Set) on the generator output, get a voltage (p-p Peak to Peak is fine). Then while monitoring that point, put 50 Ohms across generator and scope probe. If it goes

Michael, do you mean Simply3D or?simplify3d?

I use the QRP labs relay kit for homebrew radios works very nice. Below is the almost finished version I have now. 5V and do upto 5 bands or all of them if you switch them out. Listed to handle 10W

hi i am interested in the ubitx and may build one from scratch but the problem is getting a set of matched crystals for the filter. is there any supplier that can supply matched crystals. terry

I have a Monoprice Mini and a Monoprice Select Plus. Both are excellent printers. Matt Sent from my iPhone 7

Ok i have s dummy load of 50ohm this would be the thing signal generator - filter in - probe of the oscilloscope in the vcc of the filter OUT-dummy load? ?? which signal? If i input 7mhz it will let

You need to test it with 50 Ohm load (a short leaded resistor or SMD). The generator needs a 50 Ohm output, that may be the major problem. Use 100 MHz scope and good x10 probe. If you have a signal

Wow, everybody else's BITX looks so much better than mine, and I tried so hard to avoid the "homemade" look!? Haha! -- Darren, W9ZIM
