Title: Hermes-Lite SDR rig? Anyone try one?
Post by: ThaDood on July 26, 2025, 1849 UTC: http://hermeslite.com/ and https://www.eham.net/reviews/view-product/14724 HUH!!!! On the drive home last night, on the CB, local CB'ers were talking about this SDR rig. Huh, intriguing, but did they have to give this rig a name where it sounds like a type of beer?

Post by: BoomboxDX on August 01, 2025, 0748 UTC: I am not into SDRs and don't have one -- which means I, of course, don't have a Hermes.

But I've heard several hams on 40 and 20 meters who have them, and the sound and clarity they put out is excellent.

And the guys who use Hermes SDRs in their hamming swear by them. They apparently are that good.

What are the exact receiving and transmitting frequency limits ?

Reception: The HL2 can receive frequencies from approximately 130 kHz to 38 MHz, according to eHam and RTL-SDR.com. However, the useful bandscope range is limited by the ADC's sampling rate, which in the default firmware is 76.8MHz, providing a spectrum view from 0 to 38.4MHz.
Transmission: The HL2 supports transmitting within the range of 1.8 MHz to 30 MHz, encompassing the standard HF amateur radio bands (160-10 meters

Post by: Ray Lalleu on September 01, 2025, 0944 UTC: Thanks Radiogaga for the frequency limits of the HL-2.

BTW, the 'standard ham bands' are not standard worldwide, even in HF. I'm always stunned to see US hams ignoring that.
