If propagation is kind, you would likely be able to hear Iceland's HFDL network Decoding is easy with PC-HFDL, Sigmira, Sorcerer and MultiPSK. See here for the HFDL system table; there's a link that has a zip file which includes a text file version.....
Gander - Iceland - Shanwick, NAT B and NAT C routes only. Frequency in use depends on time of day and propagation conditions. I can send you my full MWARA list as a large excel file, last update was 2017.
Remember, on some routes from Europe it is possible to pass straight from Scottish ATC on VHF to Rekyavik VHF. HF wouldn't even be used until clear of Iceland VHF range I suppose - but haven't really monitored much from within Iceland so not 100% sure how they do this.
A decade or so ago, Iceland were considering establishing VHF communication sites in multiple locations across Greenland as well, thereby extending VHF capabilities (these were to be installed on proposed ADS-B sites). I don't know if they ever went ahead and did that. But if so, then quite a bit of their comms would be VHF now.
