I bought my Lime, having been fooled by their phoney specification.
Since then I made a converter for receiving 0-30MHz and shifting up to 50-80MHz using a simple circuit using a 50MHz crystal, a diode ring mixer with some filtering etc.
That area is free from major transmissions here and it works really well. Just as good as my SDR Play.
You can now buy suitable converters very cheaply.
I planned to build a downconverter for transmit but other interests have taken precedence but I see it is now common practice.
It is worth continuing with your Lime Ed considering the cash tied up in them. Maybe start off with a cheap upconverter for receiving HF?

Since HF TX seems to be a non starter with the
LimeSDR-USB, I was wondering if this product would allow mw to TX/RX on the HF
ham bands? If not, are there any other inexpensive products that may work?
