Nairobi is extremely friendly on 11300 and 5517, never a problem. Mogadishu information who sits in the UN HQ Gigiri Nairobi, are extremely helpfull and professional. Addis is fine, and Tripoli is clear, but Khartoum.... just a little to busy at times. Indian ocean is all fine on HF.
Any one know the VHF frequency for flights in Somalia now, besides 126.9. It used to be 127.45 years ago and I believe it has changed.
