you can bypass yahoo channels that do not support https by "proxying" your https url through YQL (Yahoo! Query Language) , which supports HTTPS. In the yahoo channels there is a Sources> YQL module, which you can pass https-url with this YQL request:
select * from rss where url='https://example.com/example.rss'
with this query, the YQL module will return all the elements from the original https channel.
[via HTTPS, Pipes, and YQL ]
