Q. On questions above, you mentioned that when davening without a minyan during Elul:
“Some interestingly recommend to obtain a shofar and to blow at least a Tekiah voice, which may no be that difficult to do.” Is that really required?
A. Not at all. Poskim write that when davening without a minyan during Elul no blowing of the shofar is required.
(Tzitz Eliezer 12; 40, Nitei Gavriel p. 27) as the reasons for blowing the shofar do not necessarily apply when davening without a minyan.
Horav Shlomo Miller’s Shlit’a opinion is similar.
