New firmware for RX-888

[DR53]

For anyone interested, Franco Venturi has just released a new test firmware for the RX-888 on the other forum: https://groups.io/g/NextGenSDRs/message/215?reply=1

Out of curiosity I renamed it to BBRF103_SE as before, and it works very well in SDRC, with crash-free stop-starts and bandwidth changes up to 32MHz (although it should also do 64MHz when Simon enables it). The only drawback is that the gain is set very low - I could only find two BC stations, on 7220kHz and 5960kHz, which were audible - but I imagine that that is a trivial matter to sort out .

It would appear from reading the latest thread in the NextGenSDR group that the USB Power related crashes initially experienced with SDRC were caused by an incorrect MaxPower setting in the firmware file used by SDRC, which called for more than the maximum 900mA capability of the ports, hence the crashes and "Maximum Power Exceeded" messages on startup.

Dave

Dave,

Is it usable with no attenuation? Please post a screenshot, I don't have a RX888.

Hi Simon,

Only the very strongest signals show up in the SW bands, nothing at all in the MW band - see attached.

Ah,

I think I read about a change in this logic. A RX888 is on its way to me, I'll get this sorted out when it arrives, until then we'll have to stay with the original firmware.

Many thanks indeed, Simon!

RX999 arrived, works OK. Will try new image and update support today/tomorrow.

RX999? I can't find any references to this; what are the differences from the RX888?

None, just a typo, didn't have my glasses on. Have eye floaters, can be a right royal PITA at times.

Working on RX888 today, tried the new image but really do not understand what has been changed .

I may have to release 3.0.26 with the original image, the RX888 team want to send me some code today / tomorrow so maybe this will explain what's happened.

Simon,

I have been successfully using the 3.0.26 Build 2055 with my RX-888. What new features will be available in the December 14 release?
