Our Ham Shack Hotline Number
Feel free to call us
our time zone is UTC+10
Hotline (HH) is a private telephone network
for Hams by Ham Radio Operators. You must be an
ham radio operator to get assign a HH telephone
number. There is a strictly non-commercial use
clause in the operating rules, so you will never
get any telemarketers or political call on this
phone service. The best part of all this is that
it is totally free. Yes, you have to buy an
telephone but there no monthly cost involved in
this phone service. You can call another hams
directly leave a voicemail or even join a
conference call with others hams. HH was created
with the thinking of Emergence Communications (ECOMM) use. It makes a great
backup device for emergency communications. It
works where ever you have Internet connectivity.
Some people have been hooking up
their repeaters to HH to let them talk on the
air. The network is also a great tool for
engineering in a radio circuit or for arranging
skeds with other operators.
You can purchase a suitable Phone from Amazon
and Ebay and both have worked and they have cost
from $50 to $60. Please make sure you reach out
to the sellers to make sure the phones are
unlocked. Since most home internet routers are
not “Power over Ethernet” you will need to pick
up an AC adapter or an “Power over Ethernet”
injector. The current acceptable phone models
are Cisco SPA-303, SPA-505G, SPA-514G, Linksys/Cisco
SPA941/942 and SPA-525G. You can also get the
Cisco IP Adapter SPA-112 which is an adapter
that lets you use any current touch tone phone
on the HH network.
