Today I bought a Hy End Fed antenna for the bands 10/15/20/40/80. The radiation direction will be NNE North-northeast and SSW South-southwest. Better East and West but unfortunately that is not a option. This Hy End Fed is made by a Dutch company. https://www.hyendcompany.nl
The antenna I bought is this one.
I also bought a nice small modem. The Scs DPS TNC. It very small 🙂 (about 50 euro`s on sort of ebay)
I hope that it will be possible to operate hf packet on the 105net network. Would love to connect a 300Baud link to the 105net network.
Some details about the Hy End Fed MK3

All hardware Stainless steel.
Some detials about the ScS DSP TNC
•Universal TNC and APRS position tracker with DSP,
USB-connection, output to control a switching relay
(e.g. to switch the radio's power supply).
NMEA input/output for GPS data, bi-coloured LED's,
4 DIP switch for the basic configuration.
•Optically isolated USB-connection to the computer,
generally well filtered I/O's to avoid hum and susceptibility in HF environments.
•Use of temperature stabilized oscillator (TCXO)
for high reliablilty under all temperature conditions.
•10..20 V DC supply power, use of highly efficient internal power regulators.
•Mini-Din connector, compatible to the usual transceiver "Packet-Connector".
•Currently implemented protocols: Generally AX.25, level 2.
•300 baud AFSK (old HF-Packet standard) with new developed multi-detector:
The DSP automatically processes a frequency range of +- 400 Hz
looking for 300 bd transmissions and receives
all detected signals in PARALLEL. No exact tuning by the user is necessary any more,
but always perfect reception!
•200/600 baud "HF Robust-Packet", 8-tone PSK, 500 Hz bandwidth,
automatic frequency tracking (RX) +- 240 Hz.
•1200 baud AFSK (standard Packet-Radio) with special filtering
to avoid adjacent channel interference, and degradations by AC hum.
•9600/19200 baud direct FSK (G3RUH compatible) with optimized DC removal by the DSP.
