Al, Any version should work in this case. The power difference might make a difference in the time in milliseconds that the relay might close. That to me is important when doing QSk. The relay

hi why is the price more than the $129 of the kit from india terry gm4dso

Please excuse my incomplete question re advice. ? I was asking for advice on my original post of Nov.2:?? "I'd appreciate advise on whether the 5303 should work, or whether it was a typo, since

hi is it still available and can you ship to uk at what cost terry gm4dso

I wanted to see if adding a RF amp to my V4 ubitx would improve reception and see if there were any downsides. I bought the Wideband Amplifier kit from KitsandParts to make this simple. I added the rf

Thank you for the replies. I understand that the current digital modes are used on either FM or SSB but I assumed this was largely because that's what most hams had available. Similar to how we ended

FM on the uBITx. Interesting. Not a very popular mode on HF but a good exercise in design anyway. Ill draw something up as a theoretical challenge.

Hi, That won't give the OP the FM mode. But in the Olde Days, prior to 2017, there were many mods publish to add modes to receivers that didn't have them. Mods like a BFO. Mods for a product detector

Ergo, buy a TenTec transverter... or copy one and you are done!

hi, look at this. http://www.hamskey.com/2018/05/creating-simple-s-meter-sensor-for-ubitx.html

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
