Hi everyone, Just a quick heads up, I have updated the blog this evening with a post regarding the development of the modulator microphone pre-amplifier stages. https://g6lbq.blogspot.com/ Best

Hi Peter I have not posted the files in the group for the RF Multicoupler though the schematic is available on the blog but I presume you have seen that. Are you looking to source a PCB which I can

Hi Andy, Did you ever post the files for the rf multicoupler ? I have bought a few of these and wouldn't mind building your version to see how it compares. Br Peter EI3JCB.

Hi Paul, Nice to hear from you and hope you are doing okay. Regarding using the DDS for the MK2; Providing your DDS is capable of providing two separate clock signals you should be fine. One clock

Hi Andy, hope you doing well? I’m busy with the MK2 multi bitX still as I don’t have a lot of spare time these days and it’s dragging on a little… But I was thinking of something and need

Hi Everyone I have just finished building my RF Multicoupler for feeding several receivers/scanners from one antenna. Details for the project are on my blog and I will post the files to the group in

Hi Hans I will edit the blog post to clarify the use of Arduino 2.0 and above. I have not tried Arduino 2.2.1 myself and feel no great need to move over to this version but you are correct the issue

Replying to my own post: I could not get the "old" core to play nice with the 2.2.1 Arduino IDE. Could be me, though... So, like Andy already said, just use the legacy Arduino IDE 1.8.19 and use

Hello Andy, Just a small addendum to what you wrote in your blog about the Irwell trx. You say that the software was developed using Arduino 1.8.19, and that things may not work in the newer Arduino

Hi Andy Very informative project . Well Done. Happy New Year 2024 , 73s AP2RF [email protected]> wrote:

Just a quick post to let everyone know I have updated the blog with an overview of the Irwell Transceiver VFO software. I am aware the files section is in need of some updates and hope to do that

Hi Roland That PCB is indeed a version 1 and likely came via Sunil Lakhani in India. It was considered experimental, short lived and replaced with the MK2 which was available from

Hi friend , is a old version...

This is old version i suppose. Sarma vu3zmv

Hi Andy, Thanks very much to respond on my mail. I don't know the version but I attached? a picture of the PCB. Hope this can help 73 ON4RDB Roland

Thanks Jim, That does clear up things a bit. Just learned from Andy that he did use the ADE-1-24successfully in his Irwell TRX, so I think I'll go ahead and order me some of these. 73, Hans

Hi Roland Is it a MK1 or Mk2 PCB ? Once I know which PCB you have I will assist with documentation. Regards Andy G6LBQ.

Hi Hans, The BITX20 group has some interesting comments regarding the ADE-1-24: /g/BITX20/topic/4104916 QRP Blog also has an interesting write up:

Hello All, I received from an OM in our club a blank PCB for a G6LBQ Multi band -BITX. I like to make this project , but the documentation is missing . Where can I find this ? I know this is an old

Hi all, The Irwell AF schematic shows an ADE-1 mixer. Although still available, the ADE-1-24 seems to be easier te get, and cheaper (I know, I'm Dutch, ;-) ). I have read that the ADE-1-24 can be
