The Magic Band comes alive!

When I was a newly upgraded ham in 1971, the only radio I had that would operate voice mode was a Heathkit “Sixer” — a small, 2 watt AM rig.  I had a 6-m dipole antenna taped to the inside wall.  Despite that, I recall chatting for hours with local friends, and outstanding DX that would pop up from time to time.

We are in the height of the Sporadic-E season, plus there is a VHF contest going on.  I’ve worked about 8 new countries so far (a few have event confirmed – bet they needed RI).  The waterfall is full of 6-m FT8 signals.  I don’t even have a 6-m antenna; I’m just using my radio tuner to match my Inverted-L (resonant on 160-m).

Owning a Flex-6600M is a mixed bag

A lifetime ago (in other words the year before the pandemic,), I purchased a FlexRadio Flex-6600M, along with a Maestro Control Console for remote operation.  My first year of use was plagued with problems with things that seemed basic to me; like the internal tuner simply didn’t work (refused to find solutions to situations that presented a 3:1 SWR).  The software was flaky, often requiring cold boots, and it corrupted an internal flash card several times.  While certain parts of the radio fascinated me, it was so frustrating to use that I left it unused almost a year.  That was very disappointing, as it was the only radio I was aware of that allowed for remote CW (although CW on a Flex is VERY glitchy).

A couple of months ago, Flex introduced a new firmware upgrade that fixed the tuner issue (after a year of complaints).  It now works flawlessly, and appears to handle a 10:1 situation.  In many ways, the radio seemed more stable, but after a few weeks of operation the radio would refuse to work on power-up.  Flex service responded, saying the radio needed a cold reset (a rather long process).  That restored operation, but it would fail again after a few days.  A promised firmware update fixed that issue, and introduced other problems, which is typical of FlexRadio – a fix often results in other broken things.

So here is my dilemma, I really like the Flex6600M — it is a fantastically versatile receiver (multi-receiver, actually), and it has the best Noise Reduction I’ve ever used on 80 meters.  I love being able to use it from an iPad or iPhone, remotely.  And important to me, it is the only radio that I know of that allows for remote CW operation (my Yaesu FTDX-101MP with LAN adapter does not).  However, Flex software updates tend to be buggy, and it appears that no one who understands a CW operator was involved in the development of the software (no ability to adjust weight, for example, and missing or shortened elements while in break-in).

The latest software update, to fix some latency issues, and hopefully to resolve the need for cold-resets, dropped a couple days ago.  Updating the Flex6600M was fairly simple.  Updating the remote Maestro Control Console was a major pain in the backside.  The process took over four hours and requited user responses at least three of the times it applied a partial update.  Flex blames it on Microsoft.  That may be true, but sounds more like a poor design choice up front to me.

I still love it, and use it every week to participate in a late night CW contest.  Like many things in life, it is a mix of good and bad.  I just wish FlexRadio would get serious about their software development, and get it to the point where it was two steps forward and zero steps back.

Preparing a miniPC for 24/7 operation

There are two good reasons to use a dedicated miniPC for your RMS Packet station.  The first is that the sysop user agreement you sign states that you will do you best to make sure the software runs on dedicated PC with power backup.  The second is that traditional desktop computers are real power hogs (even laptops to a lesser extent).

I purchased a ACEPC AK2 miniPC for under $200.  That box has 120 GB of SSD, 8 GB of RAM, and Windows 10 Pro installed.  It has four USB ports, WiFi & Hardwired, and BLU4.2, running a quad core Celeron CPU (1.5 GHz/2.3 GHz).  It also has room to grow as another internal SSD can be added.

As it turned out, setting the darned thing up took well over a day.  Not the fault of the ACEPC, but due to Windows 10 updates which hung.  As it turns out lots of different platform users complained of identical issues, which were due to a defect in Microsoft’s update procedures.  The fix was to go to Microsoft’s website (https://www.microsoft.com/en-us/software-download/windows10) and run the update from there.  That process took almost 9 hours to complete, but once done, the ACEPC AK2 was running the latest OS version (May 2021).

The next issue was to convince myself that the miniPC was power efficient, and indeed it is!  When sitting on the desktop idling, it pulls from 6 to 8 watts.  The maximum I’ve seen it pull when running an active Winlink session is 12 watts.  My only complaint is that the power-wart that comes with the unit (12.0 VDC out) has a pretty poor power factor, 0.52.  A few pennies more put into the design would have a power factor of 0.98.  Even so, compare 6 watts idling to a 30 watt laptop, or 120 watt desktop (a modern efficient one – older gaming PCs pull 400+ watts).   Expect a power bill less than $10 per year to keep the gateway running.

ACEPC AK2 miniPC (5.5 x 5.5 x 2.0 inches) 120GB SSD, 8GB RAM Quad 1.5 GHz CPU, Win10 Pro

The miniPC supports auto boot on power up (A BIOS setting), and of course Windows can be configured to startup the RMS Packet software.

Six Meters is Hopping!

I was upstairs noodling around and happened to use my iPad/Flex to see what was going on in the Magic Band.  Sure enough, I saw a few SSB QSOs (nothing on CW) and saw that FT8 was hopping.  By the time I got downstairs and fired up FT8, things were fading, but it was still pretty active.  And 20 minutes later it is all gone!  Such is life on 6m.

Thanks for the QSO from LA, Parker (W5AAD)!

Trouble Setting up RMS Express with CF-31 Toughbook

After having a gloriously easy time setting up my Kenwood TM-D710G and DRA-50 the other day with both the RMS Express Client, and eventually the RMS Packet software to get my VARA FM gateway up and running, I ran into a puzzling snag trying to get my IC-9700 working with RMS Express + VARA FM on my CF-31 Toughbook.

Normally my IC-9700 and Toughbook are dedicated to satellite radio, but I really wanted an alternative radio setup for VARA FM that I could use to check my RMS Packet gateway was functional.  I figured it would be a no brainer install VARA FM/RMS Express and use that setup.

Unfortunately, I ran into two problems.  The first was very minor — VARA FM only supports baud rates up to 19K.  The IC-9700 was set to 112K (Satellite guys like a higher baud rate because of Doppler corrections).  That was an easy change to drop the IC-9700 baud rate down to 19K.  As soon as that happened, I had PTT access.

The next problem was not as intuitive.  While the rig PTT was working, no modulation was produced, despite being in “FM D” digital mode and having the DATA MOD set to USB.  I could tell VARA FM was producing the sound output, because I could swap the output to the Toughbook speakers and hear the modulation.

I ultimately fixed the issue by opening up Windows Sound Mixer and discovering that the internal IC-9700 sound device “USB Audio CODEC” was MUTED.  Why, I don’t know, that’s not something I would have done.  But I had never used the sound interface in the IC-9700 before, and apparently when Windows recognized that device, it muted it.

Nothing was wrong with VARA-FM or RMS Express at all.  It was entirely an issue between Windows 10 and the CF-31 Toughbook.

RMS Packet Gateway WB4SON-10 Up

I’ve been a Winlink Express user for many years.  Up until just a few days ago, always on HF.  The interest in HF meshed with my believe that disasters are mostly either local or regional.  Sure a hurricane or winter storm can take out the internet and power in a region, but it doesn’t bring everything down everywhere.  You just need to be able to hop over the impacted area.  HF is perfect for that, and I tested and used a Winlink Express client regularly.

For a long time, I’ve been looking to try out a VHF Winlink connection, but there are very few gateways in the local area.  Yesterday my goal was accomplished when I was able to connect to N1ASA-10 on the other side of the bay. Being used to the slow speeds of HF and old style packet, I was blown away by the VHF connection speed.

Today the goal was to stand-up a RMS Packet station on my side of the bay using VARA-FM in the wide mode along with a Kenwood TM-D710G and Masters Communication DRA-50.

I was immediately drawn to the RMS Trimode software and figured that was the universal solution, but quickly discovered that was pretty much for HF use.  A process of elimination lead me to RMS Packet, which I installed.  After entering some information on myself, and discovering the checkbox to use VARA-FM, I was up and operating!  Honestly it took perhaps 15 minutes including the time I fumbled with RMS Trimode.

Here is my RMS Packet software running (and I now show up on the Live System Map for RMS):

Next step is to install the software on a dedicated miniPC and set things up to run 24/7 (I have a 100 Ah battery that is charged by solar, plus a gas generator runs for extended failures.  Even if I don’t have local internet, I can act as a relay outside the region to HF stations that are working.

Winlink with Vara FM, TM-D710G & DRA-50

After getting my VHF antenna back up in the air, I was able to hook my Kenwood TM-D-710G up via a DRA-50 Digital Radio Adapter to my PC.  I downloaded a copy of VARA-FM, and used Winlink to receive my first message via a VARA-FM station (N1ASA-10 on 145.050)

On the TM-D710G, I verified that my radio was setup for B-side external data (Menu 918), which is the right-hand side of the display.  I then changed to 9600 bps data speed (Menu 919).  {ED: I can never remember how to enter the menu, and the trick is to press the “F” button, the push the big knob in (the VFO/Channel knob).  That will bring up a list of all the menus in the radio, and 918 and 919 are in the “AUX” menu}.

On VARA-FM, under Settings/VARA Setup, I changed the FM System to “WIDE” (Setup is also the menu where you put in the license key).

Under Settings/SoundCard, the Device Input was set to “Microphone (USB PnP Sound Device)”, and the Output was set to “Speakers (USB PnP Sound Device)”.

Finally, under Settings/PTT, I selected PTT via “RA-Board” to match my DRA-50 board.

According to the log, with N1ASA in Narrow mode, and my system in Wide mode, we transferred at almost 5600 bps.

And a “Ping” looks like this:

A Drive Level Calibration was run and produced the following:

Winlink Pandemic Pause

I discovered today that I had not used Winlink Express since late 2019, and therefore I could no longer log in.  Restoring things was simple, I just made a Telnet connection and the system restored me.

With that accomplished it was time complete the upgrades and to install a new high-performance modem, VARA-HF.  It does have a free evaluation mode that will run at reduced throughput, but I decided to purchase a license ($69) and am awaiting details on how to enable it.

Despite my username expiring out, upgrading to the latest Winlink Express was simple and retained all my prior settings for my K3s.  All I had to do was configure the VARA-HF soundcard settings, close it down, then open Winlink Express (which automatically launches VARA-HF).  Gone was the older internal Winlink Modem, replaced by a “Vara HF Winlink” choice.  Opening that presented me with the familiar “Session” window, and I was able to update the forecast and channels via the internet.

I found a familiar station in Nova Scotia on 40m, and quickly established a connection via RF VE1YZ.  A tweak of the TX modulation level and I was on the air!

Mapping fellow hams in your area

I ran across a brief post from Jim, N3JT, in the January 2021 Solid Copy (CWops magazine), that described a online mapping tool that shows hams around the point you choose.  I chose FN41fn, and saw the following (after zooming out a bit):

Pretty cool tool!  Available here:  https://haminfo.tetranz.com/map

Armed Forces Day – Worked NSS & NFA

The Naval Academy station was transmitting on 7,535.0 KHz, while listening to 7,028.0 KHz.  I was able to work NSS on CW today at 17:46 UTC.  (Subsequently worked NSS on SSB 7.536.5/7.197 MHz, and NAF on SSB 7.542/7.275 MHz)

Boy, is it hard to get a non-ham call and frequency logged in DXkeeper (but doable).  I understand QSLs can be exchanged through K3LU, their QSL manager.
