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
HyEndFed 5 band for 80/40/20/15/10 Meter Max. Power : 200 watt PEP, SSB. Length : 23 meter. Bandwidth 100 KHz at 80 meters, without tuner. Aluminum mounting plate with galvanized clamps. Mast diameter 40 to 58mm. Enclosure : Polycarbonate IP67, 100% UV resistant. SO239 Connector Teflon. All hardware Stainless steel.
Some detials about the ScS DSP TNC
Technical Data •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. Metal case. •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. Modulations •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.
