There is not something else. There are digital modes that are transmitted in FM (dmr, c4fm, dstar, aprs, winlink stuff) and others in SSB (CW, wj, fsk, ft8). In my humble opinion it would be very

Hello, I'd like to experiment with digital modes on VHF/UHF and don't want any potential limitation from commercial transceivers that may be available to me. I have many questions on the topic, but to

?Evan, the design is a compromise that has deficiencies that were not originally well recognized. Thanks to some persistent work by some members (I forget all their names but one reallly worked hard

Hi Evan, In the United States it is not the manufacturers who are responsible for your compliance (amateur radio only). It is each licensee responsible for their own compliance. It's not the rule of

Ed Well that sounds like ubitx is doing well. Possibly psk31 signals are too scarce. Do compare signals, both pattern and width to w1aw. I am guessing the may be a different modulation scheme. Some

finished UBIXT build CeC v 1.08 firmware. Problem? FT8 works fine 25? contacts first try SSB works ok Psk 31 The only signal I can copy is W1AW bulletin copied at 100% All other signals I cannot

OK, I have been following all of the ubitx threads since September, and still do not know what I must do, definitively, to insure that my rig is compliant.? I thought that I had that from this

The relays are on the other side of the board? Bob — KK5R --------------------------------------------

Well, the work you guys are doing is incredible. In it’s difficulty I mean. It was much easier just to add a daughter board with the right sided relays! Minutes.

Yes, the board placement and routing could be better. Design should be improved on v5. Allison has spent months poking at uBitx's, and making careful measurements. I have not. I am curious what she

Hi, My uBITx V4 with the Nextion 2.8" is running just fine except the S-Meter. I have attached a 5k potentiometer between GND and 5V and wired the middle contact to A7. Enabled the S-Meter Checkbox, I

Mike Most of us were puzzled somewhere in putting the fine ubitx into the nice enclosure kit. I am not sure why there are 2 places to plug in the mic. I used the 4 pin connector, and wired in an old

First off, the electret mic/PTT combination share the ground or common wire.? The uBitx PTT is activated by pulling the input line down to the ground or common voltage.? The microphone is connected

Horse twice beaten (maybe more) and the problem remains. Changing relays may "help" some.? ?The problem is the board layout. IF you don't drive the radio hard to get full power it will be cleaner

Question from a really new Newby (first kit build). I have the main board of the uBitx v4 and all the connections to an Amateurradiokits case including the front panel PCB from ARK wired. My problem

Hi, The advice is in the messages. Some of the advice is to change the relays and correct the excess harmonics. The other advice is it doesn't correct the harmonics. Still other advice is the

Since we're on the subject, don't stop with your radio stuff.? I've recommended to most of my friends and relatives to start a death book.? This applies more to those of us in old houses and/or with
