Thanks for the replies, everyone! I'll update my programming and give these a try soon.

Aloha Kevin,
We had up to nine 220mhz repeaters here on Oahu last year but I’ve noticed that some of them have become offline recently, maybe due to the Coronavirus and where they were located during the massive shutdown.
Below is a map of several repeaters around the island but only lists two 220 mhz machines but only one is currently working, the 224.500 mhz -1.6 no PL WH6PD, which I use often.
The second image is from a list of 220 mhz repeaters I’ve used while driving on the Leeward side of the island. Program all of these and give them a try...

Hi Kevin, 

I have 220 as ht triband and I have a 25w mobile triband. I also have a yagi.  I think Jim KH6JQD in Waipahu is the most known on 220.  St. Francis medical center in Nuuanu had a repeater, don't know if still true. There were repeaters in Ewa and Pearl City, but unknown status.

Good job exploring.

A couple of years ago I was given a KST v6 handheld by a friend on the mainland. After finally getting a new battery and scouring the Internet for programming software I think I finally have the hang of it. The only thing is the radio is programmed for 1.25m/220MHz.

Are there any 220MHz users out there? Does anyone have a list of known good frequencies/repeaters?

Hi, Tim,

I'm only aware of a single 220 MHz repeater on island and I haven't tried to use it yet.
It's in the vicinity of Diamond Head. Look for NH7ZD on the map.

I can duct to the KH6MP digipeater by Diamond Head using the same HT that does 220, so I might try that repeater sometime.

I live in Kaneohe and my discone doesn't have an element for 220, so it'd just be the rubber-duck antenna at 5 watts.

If you'd like to set up a sked e-mail me. We can coordinate on the 147 repeater when we attempt a QSO.

YSF simplex QSOs yesterday and what YSF is

KH6CP Craig Paul
 

If you're not interested in digital voice on FM, delete this message now.


A few of us on Oahu had QSOs yesterday. We enjoyed digital's clarity and superior reach, compared to other digital modes.

The frequency was 145.5625 MHz. 

We press a single button to "go digital" and start the QSO.


It's really not hard to use. A fusion of analog and digital, just push a button once and leave it, and the radio will automatically select analog or digital depending upon what it "hears".

That's AMS - Automatic Mode Selection.


FM and digital automatically selected you say? Yes, the radios are programmed as though they are analog. If you want to enforce only digital as the originator of the QSO just push the button again to select narrow band (DN - digital narrow, the default),

or press again for wide band (VW - voice only wideband,higher fidelity, not Volkswagen!). The radios in AMS mode will automatically configure.


Want to share the frequency in digital mode? It's exactly like DCS 

in analog mode, where you set a code number to transmit.

The System Fusion equivalent to DCS is the

DG-ID - Digital Group IDentifier.


(Contrast this to DMR talk groups - you can't even hear what the other talk group is saying. Doesn't this violate amateur radio regulations?)


Repeater use is exactly the same as analog.

It's programmed into your radio exactly the same as an analog repeater split.


If an analog repeater has no tone access (KH6AZ on Oahu) then different conversations can use different DCS codes.


Hence multiple people can have separate conversations with those they choose.

Everyone can hear, but not transmit and be heard by those using the same privately shared DCS code.


Again, it's exactly the same with the DG-ID in the digital mode of System Fusion.


DG-IDs can be used to control repeater control access or link to other networked repeaters.


Rooms are the YSF equivalent of DMR networked talk groups,

whether they be Brandmeister, DMR+, etc.


Want to find out what networked talk groups there are in

YSF? If the repeater you're using is registered with Yaesu

to participate in the "rooms" around the world all you

have to do on your radio is hit the "Wires-X" button.


The repeater will download what rooms are available into your rig. You select a room and connect to it.


There are YouTube tutorials about YSF, if you're interested.

You could start by viewing reviews of radios (FTM-100dr, FTM-400xdr, FTM-3200dr)

or look at Yaesu's Education Series.


"An overview of Yaesu System Fusion II"

but that's nearly an hour and 5 minutes!

Re: Yaesu System Fusion QSO day - April 25th

KH6CP Craig Paul
 

Hi, Dave,

Evan and I had the simplex QSO, exercised Group Mode (GM), and tested powers.

I was using 1 watt and the Yaesu FT-2dr's "rubber duck" antenna.

I was 5 feet below the terrain with some moderately tall deciduous trees, with few gaps in the foliage, on the path to Evan.

I know from experiments I've run that my home station running at 40 watts, here 1 block mauka of Windward Mall, can't be heard
across the mountains past 1/3 the way down Likelike until I get to Middle Street and H-1. Likewise, from my own experience YSF
has better fringe signal performance that D-Star and DMR.

We've had people in Mililani participate in our monthly FM net. He was running 75 watts with a Yagi, able to "hit" our 147.000 repeater,
at elevation, close to the Marine Base (MCBH).

If we can get some island-wide nets going I'm willing to get a YSF mobile rig!

Yes, please do send a signal report!

By private e-mail I'd love to know your rig and antenna set up!

Hi Dave, 

Craig KH6CP and I were in a QSO from 0900 to 0930 in YSF simplex.  

Please let me know if you heard anything. We varied power between about 1 and 5 watts.  

I could hear Craig no problem at any power he used.  Craig said my audio had a slight warble when I used 1 watt, but still no problem copying. We are nearly direct line of sight, but some slight terrain and wooded areas in between us.

Between the low power of your transmitter and the mountains between us it's unlikely that I'll hear you, and I'm pretty sure that I don't hear the 147 repeater from here.  I'll at least be listening anyway, in case anyone else is on with YSF!

Hi Dave,

My HT is 5 watts so you might not hear me. 
My antenna and location are good, so I have a chance to hear you, though.

Craig and I will coordinate on our Windward 147.000 +pl 103.5 repeater.

Thanks, Evan!

See you on-the-air at 9. DG-ID 00. Shall we coordinate via the 147 repeater?

Yaesu System Fusion QSO day - April 25th

KH6CP Craig Paul
 

Yaesu USA suggests a YSF simplex QSO day April 25th using the world-wide VHF frequency of 145.5625 MHz.
(Yes, you have to change your frequency step to 6.25 kHz.)

Any takers? I'm on the Windward side! How many YSF users are in HNL and Leeward?
Thanks!


General Membership Meeting 4/21

Aloha all,
Great turn out last night.  I think we had over 30 attendees and we had almost that many at any one time.  Apologies if you tried to access via the original link.  Since the original link went out a few weeks back, Zoom Meetings had upgraded their security policies.  Hence I had sent out a subsequent link.  I'm glad we had so many join.  It was great to see many of you and that you are all staying safe.  It is unprecedented times we are experiencing.  We'll see what next month brings us.  Stay safe out there.

Aloha,
