Looking to buy a 630m SoftRock RXTX transceiver
Hello Randy,

Did you mean a LF receiver, the LF Ensemble, or a transceiver, the RXTX. There was never a LF version of the RXTX sold. If you are interesting in modifying a HF RXTX to work on LF/MF, you can find instructions on scroll down to the "Articles" section. 73, Roger On Jul 18, 2022, at 5:35 AM, Randy K7RAN <k7ran@...> wrote: |

?Good Morning Roger, I did do a little divide by 16 board that mounts just above the RXTX board in the left back corner of the RXTX board. The /16 board carries RXTX board components R12, R13, R14 and C3 along with two 74AC74 ICs and a couple 0.1uF SMT capacitors. The extended leads of the resistors provide the means of mounting the little /16 board to the RXTX board. One 74AC74 can be soldered to the /16 board along with a wire jumper to give a /4 function so that the clock function on the RXTX board is an overall /16. To then get a 630m RXTX it is “JUST” a mater of winding the inductors and transformers for 630m operation and changing a few capacitors. In recent years, on special order, I have built several 630m RXTX boards. My built 630m RXTX boards worked OK except the TX output was not quite one watt. Best regards to you Roger.

Good Day Tony,

Thanks for clarifying that for Randy and everyone. I had not known that you had made some 630m RXTX's. I had, of course, used one of your little divide by 16 boards and the chips you provided to me for my modified RXTX that continues to provide good service, including last night's WSPR receptions on 630m. As with all the many folks who have sent you heartfelt notes of appreciation recently, for myself also your dedication in making the SoftRocks available has provided me years of pleasure and learning while working with the original SoftRocks you built for me, and while devising modifications and add-ons. The Softrock40 help and support community, with you as the wise presence behind it all, has also been a valued source of friendship and camaraderie. The whole involvement has been a great highlight of my ham radio hobby life, with benefits far beyond just that. Thank you Tony, and all best wishes to you and yours, Roger On Jul 19, 2022, at 2:44 AM, Tony Parks <kb9yig@...> wrote: |
Hi Ben,
Here's a tip: I believe the Ensemble II LF receiver I have originally came with -2 mix toroids for the filters. Try using and supplying the toroids with a -3 mix. It will result in a lot less turns! 73, Zack W9SZ On Thu, Jul 28, 2022 at 7:31 AM Ben Cherry <satman39@...> wrote: Hi Randy,<> Virus-free. www.avast.com <> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> |
