OpenWebRX [using a transverter/down-converter with the Kiwi]
It seems I already made (and forgot about) a fix for the "band scale" and "select band" menu not being correct when the Kiwi is configured for transverter/downconverter mode. It's a little complex to configure. You must know how to login to the Beagle via ssh/PuTTY and use a few Linux commands including editing a text file with the "nano" program (or a similar editor package). This fix will work even if you're not running the very latest software version. It's been present for a long time.
You'll be editing a Javascript file. You don't necessarily need to know Javascript because you can follow the pattern of code that is already there (i.e. "read between the lines"). Because this file is in the kiwi.config directory changes will survive a software update. The "mi" (make install) used below only creates the file with the latest version if the file doesn't already exists. It does this to preserve any changes you may have made. That's why below we have to remove it (by renaming) before doing an "mi".
Login to the Beagle and type:
config.js defines, in a programatic way, what appears in the band scale and select band menu. You'll note a little ways down in the file a couple of variables called down_converter_2m and down_converter_6m both defined as false. There is corresponding code below those that selectively disables the numerous definitions for HF and instead uses a single "band.push(...)" via if/else statements.cdk mv config.js config.js.orig saves old file cdp mst stop server mi reinstall, which updates to new version of config.js cdk nano config.js assuming you know how to use the nano text editor cdp ku server up, test your changes
If you are using a 6m or 2m downconverter you can simply change the appropriate variable from false to true. However the "min:" and "max:" values in the band.push() may have to be adjusted to account for where the band segment actually appears in the Kiwi 0 - 30(32) MHz reception range. By default 28 and 32 MHz are specified because the downconverter LO is 116 MHz, so 144-148 MHz - 116 MHz = 28-32 MHz (Kiwi assumed set in 32 MHz mode). And of course the 116 MHz LO value needs to be specified in the config tab on the admin page ("frequency scale offset")
If you're down converting, say, air band you can add another variable e.g. down_converter_airband and the associated code or just overwrite one of existing entries. There can be multiple band scale/menu definitions if you decide it's appropriate, just like for HF. A band.push() entry can be used to define a band scale, band select menu entry or both. Read the comments in the file for details and do some experimenting. Yes, this could be done in the admin interface. But that would take a fair amount of time. Time I don't have. -

On the stats tab is a qrz.com link that has his email. Ask him what he uses. -

Is it possible to pass keyboard shortcuts via a URL? [fixed in v1.274]
From the v1.274 CHANGE_LOG file:v1.274 March 17, 2019 Added URL parameter "keys=" to apply specified keyboard shortcut keys upon connection. Example: "keys=xyyys" would cause the control panel to be hidden ('x' key), top and label bars to be hidden ('yyy' keys) and spectrum display to appear ('s' key). The shift key can obviously be used (e.g. capital 'S' for waterfall auto-scale) but the control and option keys cannot. But this should not be a significant limitation as it only effects parameters which can be set in other ways (see below). The keys used to enter values and options into the frequency box cannot be entered using this new parameter. Use the existing "f=" URL parameter instead. Remember that you can directly set the zoom value using the f= parameter since the other components are optional e.g. f=usbz7 f=/750cwz12 f=z4 Added URL parameter "wfm=min{,max}" to directly set waterfall colormap control values. Example: wfm=-90 (WF max value is unchanged) wfm=-120,-60 (changes both values)
