Simplex test

We have talked a couple of times about doing another Simplex net, and we just haven’t been able to get it together to successfully have one.

We are going to give it another try, this time a little more structured.  In the past we have talked about the size of Polk county, and that we have it divided up into 4 regions – north west, north east, south east and south west, and have assigned simplex frequencies to all 4 along with a common county wide frequency.  These are:

•        County Wide:
o        2m – 145.510
o        70cm – 446.150

•        North West:  North of SR 542/US92 and West of US 27
o        2m – 147.465
o        70cm – 446.050

•        North East:  North of SR 540 and East of US 27
o        2m – 147.405
o        70cm – 446.025

•        South East:  South of 540 and East of US 27
o        2m – 147.585
o        70cm – 446.075

•        South West:   South of 542/US92 and West of US 27
o        2m – 147.420
o        70cm – 446.125

All the above are Simplex, no tone.

Steps for this Simplex test:
1.   Meet on the WC4PEM repeaters

2.   When the primary Net Controller gives the instruction to do so, go to the VHF Simplex frequency assigned to your region of the
county.  For this test we are just using the VHF frequencies.

3.   Check the frequency for use.
a.      If not in use, give your callsign.  Once another station has come back to you, decide which of you will be the region
Net Control.
b.      If the frequency is in use and not by ARES, request from those using it if they can standby and allow the Simplex test
– if they will not, do not push the issue and return to the WC4PEM repeaters and await instructions.
c.      If another station that is participating in the test has assumed region Net Control, then proceed as a check-in and
give them your call sign.

4.   The region Net Controller will then ask for check-ins and request any relays of those that are attempting to check in but that
the Controller can not receive.  As a guideline, use:
a.      This is (your call sign), ARES Net Control for Region (your region) Polk County.  Please check in to the net, one at a
time.  If you hear a station that is attempting to check in that I have not acknowledged, please relay that station’s
call sign.
b.      Give the region net check in process approximately 10 minutes.

5.   At the end of the region net check in, the region Net Controller should go to the county wide VHF Simplex frequency and attempt
to contact the County Net Controller.
a.      If contact established, give the county Net Controller a count of the stations that you were able to contact along with the number that were relayed in, then go to the WC4PEM repeater
and wait for the Net Control to return from the Simplex..
b.      If unable to contact the County Simplex Net Control, go to the WC4PEM repeaters to await further instructions.

That is it.  Pretty simple and should not take us more than around 30 minutes.  Might want to print these out to make it a little easier.

When?  I’d like to do this on Wednesday, February 21st, at 2030 hours.  This will allow us to run the test and be able to discuss it at the ARES meeting the following evening (February 22nd).

If you have any questions, concerns or need clarification on any of the above, please do not hesitate to contact me at

I am planning on our having another test in a few weeks on a Saturday or Sunday afternoon.  I would also like to run an HF test net prior to June 1st.  Ideas or comments on either of these would be appreciated.

Hope we can get a good turnout for this.
