QRV on 4m band

In addition to 6m magic band, I am now able to work also on higher one - 4m in all modes including digital modes but I prefer FM. I will be definitely trying to make contacts in digital modes during tropospheric conditions in the summer months but now the FM mode is the priority for local communication and coverage tests. I use Icom 7300 and Anytone 5189 transceivers for this band and dipole antenna from Sirio. I will be ready to go /M very soon, I'm just waiting for the antenna, even though I don't plan to install the Anytone radio permanently in the car yet. I will do maybe sometime later for example in the summer.


Nowadays, I am able to use 4m from my base location through HF antenna switch only because I do not have an extra unused coaxial cable to connect to the antenna. Luckily I had one free antenna output on the antenna switch. That's why I am not permanently monitoring the band yet but I make a CQ  call occasionally. I assume I will install another coaxial cable in May 2023 when temperatures will be acceptable for handling with coax cable so I will be permanently monitoring this higher magic band sice then. My standby and call frequency is 70,450 MHz FM and maximum power 45-50W.

FM mode in Slovakia is allowed from 70,250 to 70,500 MHz in 12,5 kHz steps.
