No no, partly yes. The amp side is correct but on uBitx side connect one end of coil to ground and other end to TX (12V on TX).. simplest. I usually dont recommend connecting to PTT line as any mishap

Only experimentation will tell John! Mt3608 is the boost version, mp2331h is buck version. For some reason I am not able to open those net pages to share with you all. Some problem since last night.

Good one Luca, Be honest about it, ive never burned up a radio or finals after i achieved my general class license back in the day.And anyone on a tight budget like me, you just dont throw away money

I built a 70 W amplifier, but it never did work. I believe that the directions I had said that you can only get 30 watts of output out of it without purity issues, and it is more than 3 db down as

Evan, Thanks. That is what I needed to know. Now to determine which of the six pins is #1. Schematic uses different numbering sequence than the data sheet for the relay. K3, KC1,KB1 and KA1 all show

Can you hear what is going on or is it all visual? BO Sent from Mail for Windows Sent: Wednesday, August 10, 2022 8:18 AM To: [email protected] Subject: Re: [BITX20] Ft 8 on the v-6 I use this guy. Or

Hi The pleasure of using a radio like ubitx Is to esperimenti new solution to old issues! Burning out the radio Is the First! ? 73 Luca [email protected]> ha scritto:

Yes, that is what I would do. In the photo it looks like it's filtered on both the input and output. -- Jerry, AC9NM 手中的鳥在灌木叢中值兩個

I have built that kit and have had issues meeting purity requirements with a 5-pole LPF.? There is also a potential issue with VSWR on the input to the amp.? I would review this article before

Ideally the amp would go into TX 10-20ms before the radio as well as staying keyed for 10-20ms after the radio stops transmitting. This would prevent HOT keying of the radio and burning of relay

The filter is, unexpectedly, needed on the input side. - f

Niels, Did you put the filter on the input side of the mini-360? -- Jerry, AC9NM 手中的鳥在灌木叢中值兩個

Michael, I would not connect the PTT to that point on the v6 uBitx.? On the mainboard, K1 has a TX tag on pin 1 of that relay.? You want to tap into that signal and connect to the new PTT relay.?

David, Going to use this kit - https://www.ebay.com/itm/272629942946 - Seems to work well. I have the LPF already built. Just waiting on the Amplifier. KG5UMH Michael - DM93am

Tried adding filters to the mini-360 buck-converter. It helped a lot. now I can hear the same as on my old ft-77. oz9ny, niels

Hi, I saw that Tim (in /g/BITX20/message/91212 ) has hade same problem. I asked him if he can use the QR-functions ... I mangaed to compile (editing the "txt_maxl", but i cant use
