70Mhz transverters are rather rare except for the new ones from Ukraine. On eBay you will find different vendors, each one claiming the originality of the product. Actually I gave once a try for a 432

LEDs can be convenient for giving an idea of the SWR and maybe PWR. SG-lab microwave transverters have them and you have a clear indication of what is going on just watching two LEDs. LEDs that change

My softrock RXTX for 15-12-10m delivers a little bit more than 1w on 15m and around 0.7w on 10m. It is excellent with my TenTec 2m transverter. TX audio is very good but depends on software settings a

An IC-7300 will never be a QRP even running at QRP power. QRPs are the ones listed on https://www.eham.net/reviews/

10 watts are not too few even on SSB. An antenna with gain and a well shaped radiation pattern may make thing easier. However to me a compressor might help too: it increases average output and dependi

Loris, you are right! 50% of loss is a lot! If I used 500w, I wouldn't like to loose half of the power warming the climate... But 3db in RX is usually negligible and I find the ubitx (I have ver.3) se

Satisfaction to me is being able to use and to exploit minimalistic HF rigs, render them effective beyond imagination. Apart from HF Signals, I really have fun with Softrock RXTX. What is missing from

How many mV is the output of this mic? Does It have a compressor with clipping or just an amplifier?

Look at the schematics. Which CB amplifier is that? I would think to optimize the input and the output impedances of the amp (sorta of tuners), ferrites chokes at both the input and the output, effect

What about the FCC 15db gain max for the amps?

Hello everybody. I have a version 3 of the uBitx. Is the negative feedback in the finals necessary or at least useful for the stability of the push-pull amplifier? I have seen the 26db 10w amplifier b

There are radios with the Si4735 instead of the Si4732. I don't really know the difference even looking to the datasheet. There seem a bit of confusion, at least to me, in the descriptions whether the

Does It happen with other receivers/trasceivers too? It might be MW transmitter nearby but also a local FM broadcast station. The low pass filter built into the Ubitx removes the FM broadcast of they

Please forgive him. Evidently he was mistaken in joining this group.

According to Franco Rota rfmicrowave.it It can be used as detector for applications up to 2 GHz, as mixer up to 1.5 GHz, often used also as RX input protection at HF and VHF thanks to its low capacity

Great! I would like to know which transverters he uses and whether TX stability is fine or how is made acceptable. I had used in March 2019 a TS811 and a SGlab transverter, which was fine, but I would

Hello everybody and HNY, Has anyone tried to operate QO-100 sat using a Ubitx? What a pity most operators in the US can't uplink that SAT!

I believe the MFJ-915 current balun/choke/isolatori Is a good product, but but but I can I easily test it's effectiveness?

I am not totally sure, but that DC Path at the antenna input might provider some degree of protection in case of statics.

Before uBitx GDP was a good proxy for happiness.
