Abstract: High frequency (HF) radio communications offer latency advantages over fiber-optics in certain long-distance communication applications. As a result, there is interest in using HF for high-frequency trading (HFT), to make trans-continental market decisions that leverage the lower latency path of HF channels. Examples of these receivers include the AOR AR8200 and Icom IC-R20. Ultra Lite Portables – Often defined as being very small (palm sized). Some like the Grundig G6 offer full coverage of the HF spectrum (usually 3-30 mhz, although purists will sometimes point out that there is a 2 mhz broadcasting band..), dual bandwidths and even SSB reception.
