As I use my rig mainly in portable situations, I want to try to avoid field failures due to shocks and vibrations.? I am particularly concerned about the toroid coils and maybe the larger

Cyanoacrylate (superglue) would allow a quick repair and the toroid parts would be closer together due to a thinner layer compared to the usual two-tube adhesive. Regards Lawrence

To my ear the lm324 gave a better result than the TLC274... I'll start posting out the boards. 73...

Ok, some results:

Great info - thanks. My SSM2167 module has just landed from the slow boat... Nigel.

you need to select BAT54S the one with suffixx "S" it is two diodes in series. two such wired peoperly work as ring modulator. All the best regards sarma vu3zmv Regards MVS Sarma

I thought I would mention this as it could be helpful to someone. In another thread there was the mention that inserting an SSM2167 mic compressor circuit between the microphone and the uBitx

Not to confuse things, but the BAT54 comes in several different pin configurations:

However, a broken toroid after having calibrated a coil, If glue repaird, would change its value. Perhaps the inductor value woudl reduce silghtly. After the suggested gluing, I would recommend to

A bit of 5 min epoxy to hold them together tightly is all I would do. Just bits of metal suspended in ceramic/resin.

Have you noticed any cross-talk caused by the cat (USB data) connection to the RX audio? 73 Nikos SV1IYF

Hi, I recently received a BiTX40 (thanks to the people who helped me with finding the manual).? While going through the various topics here, I was taking a closer look at the board and noticed L2

Hi All, Here is another option to add paddle key to same port straight key. by soldering resister 10k & 2.2k to stereo jack. 73 de E29AHU Choke

Hi! There is a nice AGC implementation using? mic compressor chip SSM2166 in Polish SSB transceiver kit "Omega". We can try substituting the AF preamp with a module from? Ali.. (baba..) and his band

Ah.... thanks so much!? Great to know.? I'll follow up with the external audio.?? Tom AB7WT
