Digital Voice / Yaesu FT1D/FT1XD: Tips on exte...
Last post by DU2XXR - Oct 03, 2023, 02:53 PM
TL;DR Running digital/AMS and APRS at the same time takes a big chunk of battery juice.

I'm back to using my FT1XD as my primary radio. More accurately, I'm using my FT1XD and FT1D. Coming from the FT3D, I'm now beginning to appreciate the battery life of the FT3D more, because it's the thriftiest of the Yaesu digital radios, at least on paper, as we discussed here before.

I used to complain about the FT1 platform's battery life after being spoiled by my FT3D, which I used as my primary HT for over a year. But I may have spoken too soon. I was comparing the battery performance between FT1(XD) and FT3D with APRS turned on full time, as well as with digital/AMS standby in the A band.

With APRS on, I initially tried having digital/AMS turned off on the A band, and it resulted in some improvements. After all, based on specs, the FT1 consumed the most additional current when digital/AMS is turned on, at +65mA, compared with +20mA with the FT2, +6mA with the FT3, and +3mA on the FT5!

However, I realize that when both APRS (on band B) and digital/AMS are turned on in the FT1 (on band A), there was excessive consumption, and the radio became too warm even just on standby. It's not scientific (I was not able to measure current) but more of an observation. Thus, a fully-charged SBR-14Li would run out in around 8hours or even less.

I discovered that even on dual-RX and with digital/AMS turned on, battery life was significantly longer with the FT1(XD), for as long as APRS was turned off.

Having APRS probably resulted in the biggest hit on the battery, because the RX save feature was automatically rendered useless with APRS. The radio's receiver needed to always be on standby to receive APRS packets (whereas with APRS turned off, "RX save" only wakes up the receiver every XX ms and wakes up full-time when there is a signal received).

And probaly because standby was always ON when APRS is turned on, the additional load from digital standby on the DSP became an added culprit for heavy battery usage (that's the +65mA as per spec).

So my conclusion, having BOTH digtal/AMS and APRS takes a big hit on the battery. Having only one - either digital (plus dual RX on the B band) OR analog on the A band plus APRS will not be so bad.

My solution now is that I use my FT1D for voice - our Fusion repeater on the A band and our 2 meter FM on the B band or for crossbanding when I am near my home. And I use my FT1XD primarly for APRS, sometimes using the A band for analog.

By the way, I'm using the vinyl case on both radios, as some of my batteries have their tabs broken off, and the case holds them secure against the radio. It's not as good as buying new batteries, but I have a handful of SBR-14Li that still perform well except for having broken tabs.

Successful speaker replacement. After my first attempt at disassembly to see if a bad speaker is really the culprit (e.g., whether it could be repaired with contact cleaning or realignment), it now only took me less than 10 minutes to disassemble, replace the speaker, and reassemble the radio. Speaker itself cost 500 pesos from the local yaesu distributor, or an equivalent of US$8.80.

Digital Voice / Re: YSF hotspots/nodes/repeate...
Last post by DU2XXR - Sep 26, 2023, 05:43 PM
As an example, these are the stanzas we're using for the DX1ARM YSF:

[DGId=1]
Type=YSF
Static=0
Name=Parrot
Local=42023
RFHangTime=10
NetHangTime=10
Debug=0

[DGId=8]
Type=YSF
Static=0
Name=DX1ARM
Local=42022
RFHangTime=1
NetHangTime=1
Debug=0

DG-ID 1 directs to the parrot/echo so we can test our audio quality or at least determine if coverage is good when there's no one else to talk to.

My purpose here is so that the YSF reflector can run alongside our WIRES-X room as a backup, without the two looping. The WIRES-X node uses a different DG-ID from the YSF node. The reason for the short hangtimes is so that traffic to WIRES-X no longer get re-routed back to RF via the YSF.

Essentially, this renders our YSF node a receive-only node from RF, until the time I manually activate the link full-time.

That can also be achieved by using a static DGIDgateway link, which can perhaps be done by something like this:

[DGId=1]
Type=YSF
Static=0
Name=Parrot
Local=42023
RFHangTime=10
NetHangTime=10
Debug=0

[DGId=9]
Type=YSF
Static=1
Name=DX1ARM
Local=42022
RFHangTime=15
NetHangTime=15
Debug=0


The Local ports are arbitrary and are mostly meant to prevent collisions and perhaps can be used if there is linking to/from other services needed. In the above stanzas, the DX1ARM YSF connection is "Static" meaning it will continue receiving traffic from the network even after the hangtime, until the time that a different YSF is selected via DG-ID or an empty DG-ID is selected.

The routing is done via the "Name" item. DGIDgateway uses the equivalent reflector from the Hosts.txt file and routes the traffic accordingly. Similarly, for any traffic received from the network, DGIDgateway tries to match the name with the stanza identifying the DG-ID and sets the DG-ID being transmitted by MMDVM locally to that ID. This is useful for routing and linking purposes, if so desired.

The discussions also point to other options, such as YSF2DMR, YSF2NXDN, IMRS, but I have not had the time to explore those.

One lesser-documented feature in Pi-Star is the DgIdGatway, which lets users route their transmissions to their desired YSF reflectors (or YSF2DMR talkgrups, FCS reflectors, or other gateways like parrot, local, etc).

Some steps in enabling it:

1. Access your Pi-Star terminal via shell.
2. Make sure your filesystem is writeable:

rpi-rw
3. Edit /etc/dgidgateway using your favorite text editor. Need to be superuser.

sudo nano /etc/dgidgateway
4. Add lines as necessary. You may refer to examples found on the DgIdGateway github on how to set up your targets: https://github.com/g4klx/YSFClients/blob/master/DGIdGateway/DGIdGateway.ini

There are also some discussions here: https://groups.io/g/OpenDV/topic/dg_id_gateway/76993305

You will need to establish whether your targets are static (Static=1) or dynamic (Static=0). If static, that means you will be primarily connected to that reflector or link after the transmission. Hangtimes can be defined.

5. Enable the dgidgateway service.

sudo systemctl enable dgidgateway
You can then start or restart the service.

sudo systemctl start dgidgateway
You might need to restart your hotspot, either through the web interface or just by rebooting.

sudo reboot
6. You can then change the transmit DG-ID on your radio to direct the traffic to its intended link. For example, a DG-ID of 08 might direct you to the DX1ARM 78427 YSF room, while a DG-ID of 09 can direct you elsewhere. DG-ID 01 might be defined as a parrot reflector for checking your audio. If you use YSF2DMR, you can also direct your traffic to your defined TG.

Changing DG-IDs is much simpler than doing DTMF or connecting to the "WIRES-X" interface for changing rooms.

HF and Propagation / Mocking FT8
Last post by DU2XXR - Sep 19, 2023, 01:29 PM
From https://www.facebook.com/groups/12699105116/permalink/10168096481800117/?ref=share&mibextid=NOb6eG

Mocking FT8

A few years ago, Joe Taylor, K1JT, a Nobel prize physicist, had created a new digital mode. The co-assistant in the project was Franke, K9AN so the mode is officially known as "Franke-Taylor design, 8-FSK modulation, FT8".

In essence, the FT8 enables decoding of signals 10dB below what we perceive, by ear, as a noise floor.

A revolutionary development which made a huge impact on amateur radio, worldwide.

What Joe and Steve did was simply amazing: they've literally given 10dB to every amateur in the world, free of charge. Think of it this way: you wake up in the morning to find that your vertical antenna is gone, and instead, you see a 20m tower with a 3 element yagi. And not just any yagi - but a yagi that works on any band from 160m to gigahertz.

Practically, FT8 allowed an average amateur running the most basic setup - a 100W into wire - to make two way contacts he could previously only dream of.

Yet instead of sending K1JT a 'thank you' letter, a note expressing amazement and gratitude, some amateurs - to this day! - find a great deal of amusement mocking not just the FT8 mode, but operators who use it on the band.

In their view, there are two major 'problems' with FT8: the operation could be automated, so a less scrupulous amateur could simply let the computer do all the work. "You go to bed, and in the morning, there are 100DXCC in the log, thank you very much". The second complaint is that FT8 contacts are just too easy to make, therefore, FT8 is nothing but a vending machine that spits out DXCC awards.

Yes, it is true that cheats will cheat, no matter what. There is no sport or hobby without cheaters, and FT8 is no different - people do cheat. But that itself has nothing to do with FT8. Using remote receivers on SSB or CW in order to hear signals that otherwise are too weak to hear, or a practice of "working DX" on behalf of a friend, has been around for decades.

The second claim is simply ridiculous: anyone can work their first dozen countries with literally one watt and piece of wire. With 100 Watts and a simple vertical, working 200 countries is still relatively easy and could be achieved in a year - or less. But pass 200 and things are starting to get very difficult. And to work all 340 it would take a couple of decades - or more - even for an operator running kilowatts into directional antennas.

Those who are loudest mocking FT8 are actually those who have never achieved much in DXCC chasing. People who were never serious about the hobby, those who have no clue how difficult it is to work a rare DX.

FT8 is not easy. Definitely not in an urban environment where local noise is painfully high, where putting up an antenna is prohibited by council or local strata. For those who are forced to live on tiny blocks, or in a strata unit or retirement home, to them, FT8 is the only way to enjoy our hobby. We must respect that.

As they say, cynicism is the lowest form of entertainment. Making fun of amateurs who understand and enjoy FT8 is the lowest form of 'social media' engagement. Next time you see a meme like the one above, pause for a second, before hitting the like button.

Our goal should be inclusiveness - encouraging amateurs to engage in any form of communication that suits their needs, their technical and educational level, using whatever equipment they have at their disposal. To respect those who are serious chasers equally as those who simply turn the radio on to say 'hello' to an old friend down the road.

Thank you Joe.

QuotePhones used to belong to a household; now they're personal property. A shared line was irritating when it was the only option: Teenagers (or modem-connected computers) might tie up the phone for ages, a few handsets scattered throughout the house limited privacy on the phone, and anyone could fill your home with telephone bells at any time, day or night. But in exchange, your house got a common line in and out. In a small but important way, it emphasized the household as a unit, one with common interests, a hub through which contact with its members could be made.
