Okay, since Friday's BIG news about the RX1_L Port modification, some were probably wondering what the RX1_W Port looks like...Well, I'm here to impart that information to you and show you the results...
First off, the mods I did were to the RX1_L Port (shown in the yellow circle) and RX1_W Port (shown in the red circle). All you need to do is remove the coils from these two spots and you're DONE. No more mods necessary (for now, later on when there are apps that support two receivers, you can do this to the RX2_l and RX2_W Ports, too). Here's the reference picture to use for V1.4 Boards:
Once you remove the coils from those two spots, you'll have GREAT HF receive. Now, the receive for the RX1_L Port has been well documented by me, @nn4f_radio, and others - so I won't be shooting pics of it, it's the same as Friday's pictures for V1.4 hardware. The Wideband Port results follow for bands that are active now in the early afternoon here in Iowa - more to report later for 80/75m later tonight:
Here is the AM Radio Band (tuned to 1450 kHz AM KMRY in Waterloo, Iowa) here in the U.S. with the Wideband Port:
Here is 5.0 MHz WWV on the Wideband Port:
Here is the 40m Band with the Wideband Port:
Here is the 20m Band on the Wideband Port:
Finally, here is the local Weather Radio Station WXL61 In Cedar Rapids, Iowa at 162.475 MHz on the Wideband Port:
EVERYTHING sounded good in the HF Band using this mod. Nothing was distorted and everything demodded perfectly clean on AM, LSB and USB modes. The only anomaly I found was that the 162.475 MHz it was pretty scratchy sounding and I was using the Narrowband FM Mode in 5 and 8 kHz - this may be because of how the software app (SDRConsole V4.0) demods FM using this port or it may be a byproduct of the port itself in the firmware of the LimeSDR. It's usable in the upper bands, it just sounded scratchy (Note to the developers).
So - there you have it. If you feel up to it, remove the MN26 coil from the board (shown in red) and you can have two ports to use that act pretty similar for HF with great gain. As I have said before, more testing is needed before I can render a final assessment on this, and toward that I will continue to use this Wideband Port to study its characteristics.
Have fun with it..!
