Hello. Welcome to my page @ BM. My name is Guillermo, HK4KM.

Latest interest is learning CW and going back to QRP HF which I enjoy very much.  Now working everything QRP 99% of the time.

Recently built and programmed a BT dongle for my Elad FDM-DUO HF rig.  I use it with the BlueDuo app on an android tablet.  It gives me a waterfall display and all the controls for the radio.   Running Allstar node 49757 which I've connected to my DMR TG 7324 and YSF reflector CO4 KILO MIKE.

Interested is in Network radios.

Operating HF with a variety of radios such as the Yaesu FT-991A, FT-950, Elecraft KX3 and ELAD FDM-DUO SDR direct sampling radio.  I work low power to a vertical multiband antenna at the QTH and a multi-band mobile from Comet when mobile.

When mobile or at the QTH I'll be on my DMR TG 7324 group or my YSF CO 4 KILO MIKE reflector.    I run reflectors for D-Star (XLX732) and YSF (CO 4 KILO MIKE) from my own network.

Previous call signs: HK4GSL, HJ4GSL.

QSL via LOTW ONLY. Please DO NOT send QSL cards via postal mail or bureau. I will not answer those.
