Re: FIRMWARE UPDATES?

Thank you for your kind reply Guido, I have worked with AGC design for a couple of transceivers. My current boat anchor rig is a Cubic 102BXA. One of its unique features is that it has a variable AGC decay time on the front panel. Here is my Swan version of the rig- the same electrically: http://www...

FIRMWARE UPDATES?

I have had more time to work with the transceiver and have seen some issues that perhaps could be solved in firmware. Is it possible to offer another AGC menu option that has a faster attack time? I am seeing a large overshoot at the beginning of a strong CW character and beginning of the 1st word (...

Custom Packaged (tru)SDX

My requirements for this great rig are likely different from most. I dont require a tiny rig but rather wanted to have an internal rechargeable battery (1800mAH), lighted pushbuttons (for night time use), larger speaker with more volume and better bass response, and a dedicated AF Gain control. I al...

External Microphone

Pardon me if this has been discussed. Looking at the schematic, it appears that the external microphone should also be electret. Does anyone have input on a microphone that sounds good with the rig?

Tnx,

Re: Orange 3D Case - menu button on mainboard.

Likely not the answer- but are your switches all mounted and seated squarely to the PCB?

Chinese Vendor unit FB

I just completed building my (tr)uSDX Friday night. Still awaiting parts for my custom cabinet. I had to adjust the 27MHz oscillator down to 26997.900KHz in order for the display to agree with my Rubidium slaved signal generator. Now dead on. The 40M Minimum Discernible Signal measurement is -124dBm...

Re: (tr)uSDX power, efficiency and filter optimisation

Just reading this thread and one thing I can comment on (my company manufactures a broad range of RF filters) all the filter caps should be NPO/COG. Caps with temperature characteristics like X7R, Y5V etc have no place in RF L-C circuits. They are Hi D (low Q).

Re: (tr)uSDX now officially available from China

I believe you are correct Joel. I did receive a repsonse from the vendor- which was of no help as it directed me to the pages regarding loading Bootloader and firmware. Maybe that means neither programs reside in the radio. It will take me a while to machine my enclosure and awaiting on Switchcraft ...

TRUSDX on AM?

Can anyone comment on the RX and TX AM quality? I routinely use AM on HF, and the little rig would be fun for the local guys and now 10M AM is opening daily.

CUSTOM ENCLOSURE

I may have missed this information, but are there dimensioned drawings for those of us who want to machine our own enclosures?
