Elecraft K4 Case

In preparation for a remote POTA and CQ WPX SSB outing, I wanted a case for my Elecraft K4D. After looking around for anyone that may have used a Pelican case, I stumbled upon a reference to Elecraft’s web site where they have a soft-side case for the K4. It comes with foam to surround the radio. As it is soft-side, it is not made to be checked but who would do that to a K4? This is one where the radio will be with you either in an overhead or in your trunk. This case is available for $150 direct from Elecraft via this link: https://elecraft.com/products/es100-k4-carrying-case

I took advantage of Elecraft’s free shipping when ordering from a hamfest as I ordered mine at the Orlando Hamcation.

Here are some pictures from when I packed up the K4 today for my upcoming trip to Crooked River State Park for the Greater Atlanta RISK Tournament.

Shack Update 2023

It has been awhile since I posted about the QTH so here goes. Beth and I moved in September 2022 to Clearwater, FL. We decided it was time to leave the beach. While it was certainly pretty looking over the water from the rocking chair on the deck, honestly the wind was getting a bit too much for me. Fortunately, the buyers wanted to leave the tower there so I did not have to arrange for that to come down. A few of the guys from SPARC came over the took down the vertical on top of the tower and the OCF antenna.

Skipping forward to this place in Clearwater, Beth wanted to be on a golf course for the social and tennis aspects of it. I wanted a poll again and to be closer to northern Pinellas to be closer to the gang in UPARC. Madeira Beach was too much of a haul to go to things up here so it is nicer to have people closer to us. Of course, my main concern was avoiding going back to a place with deed restrictions at all costs. We had a few false starts on this house on the Countryside Country Club golf course but we finally settled on a good price and bought it. Oh and there are absolutely ZERO deed restrictions of any kind!!!! This is one of the few places that backs right up to a golf course that does not have deed restrictions. This was a great find.

While this house is bigger (4174 sq. ft.), it is one level with a 3 car garage. We had a much bigger garage in Madeira Beach which meant more places to store my ham stuff. That is both good and bad as I tend to forget what I had in that much space. I have been struggling trying to decide if I want to put up a tower here. Given my style of operating HF, I settled on a roof tower on the flat roof over our lanai out back. I ordered a Mosley MP-33-NW antenna to go on the roof tower with an Alfa Spid RAK rotor I had laying around for my tower project in Madeira Beach. That antenna does not get here until some time in June if Mosley’s estimate holds true so I am thinking int he interim, putting a 6m beam I again already had on the roof tower for June’s Sporadic-E season to pick up some 6m contacts.

In the shack, I reused most everything I had in the prior house. The great guys at UPARC came over and put the Morgan lightning arrestors in the KF7P box and sunk a ground rod. They also put up the tri-band vertical (2m, 70cm, 23cm) and even found a way to install the 40m – 10m OCF antenna I had on the Madeira Beach tower previously.

The Elecraft K4 works great with the Elecraft KPA-1500 (it is like having a 150 watt transceiver). The KPA-1500 tunes the antenna everywhere it needs to and the antenna works great for as low as it is and being essentially a dipole. I am looking forward to the beam to get a bit more gain on 20m, 15m and 10m and the rotatable dipole elements on 17m and 12m.

The Flex station (Flex-6600, PG-Xl and TG-XL are installed in the corner of the new shack as station number 2. It sure would be nice to have a Maestro when they finally start shipping that again. I plan to also make the Flex station available for people to use as a remote so people that may not have an HF station at home can use my station when I am not using it during the workday (yes, 4 more years of work until retirement).

Controlling the Elecraft K4 and KPA1500 with Home Assistant

For awhile now I have wanted to be able to have my “Goodnight” scene in HomeAssistant turn off my network attached ham gear. I finally had a chance to do some experimenting and created this config to turn on and off the KPA1500.This sends a command via UDP to the amp to turn it off and uses Wake_On_LAN to turn it on. A similar thing could be added for other device types. This is added to the configuration.yaml file.

Put your real MAC address of the amp next to mac. If you mac address is 54:10:01:02:0A:0B, then the line will read mac: 54:10:01:02:0A:0B

switch:
– platform: wake_on_lan
name: Elecraft KPA1500 Amplifier
mac: 54:10:01:02:0A:0B
turn_off:
service: shell_command.turn_off_kpa1500shell_command:
turn_off_kpa1500: “echo ‘^ON0;’ | nc -u 192.168.1.2 1500”

It assumed the IP address of your amp is 192.168.1.2 and it is listening on the default port 1500. Note this is a UDP connection so the command is sent with netcat (nc). ^ON0; turns off the amp. Reference to wake_on_LAN in HomeAssistant is here: https://www.home-assistant.io/integrations/wake_on_lan/. This also assumes you are on the same network as the amplifier.

If you are doing this from a script on a Raspberry PI for example, you can use etherwake (sudo apt-get install etherwake)

Now for the K4…
Since the K4 does not yet support Wake_On_LAN, you have to resort to the old ways to remotely turn on the radio. But once the radio is on, then HA can check the status and allow you to turn it off. So for my use case, I can send a command to the radio to turn off as part of my ham shack off scene (goodnight).
In the switch section of the configuration.yaml, add the following:
– platform: telnet
    switches:
      k4:
        name: “Elecraft K4 Transceiver”
        resource: “192.168.1.108”
        port: 9200
        command_off: “PS0;”
        command_on: “PS1;”
        command_state: “PS;”
        value_template: “{{ ‘PS1’ in value }}”
        timeout: 0.9

Chronology of a New Ham Radio Release

Part of any new radio release is a treasure-trove of commentary on the new radio’s email reflector. This is a summary of those topics so when you order your new radio you can recognize some of these common patterns. I started this with the Icom 9700 and it has been true for every new radio since then.

  • Discussion if the rumored radio will actually be sold and when.
  • General hand-wring regarding the vendor’s included/missing features.
  • Consternation regarding how long it is taking to release anything.
  • The inevitable price guessing (and first round of retail economics and pricing strategies with a side of currency exchange issues).
  • The first round of commentary based on the aforementioned speculated price as to why “The old model will do me just fine, thank you” or “That is too much for that style radio so I will not buy that” with no discussion if the writer actually could afford one.
  • The first lull in activity as people seem resolved to wait patiently (a very short lull).
  • First hamfest sightings which then cause the cycle to repeat after lambasting the temerity of the videographer to not show the exact feature others wanted to see.
  • More discussion of price as the dealers start to take reservations.
  • Speculation if one should buy a so-called gray market radio (i.e., buy a radio for the US market in the UK/Japan/EU and modify it). This is always coupled with another round of currency valuation discussions where people attempt to equate the price strictly on the current exchange rate without regards to local market dynamics that really set a price.
  • US market price announcements by varying dealers couple with another round of pricing discussions that frequently including basic retail economics discussions like overhead (or lecturing some on why they are not considering overhead). These discussions show a population subset that will never be happy with a price unless the manufacture sent them one for free to keep forever.
  • First orders converted from reservations take place, which starts a general discussion on why one’s dealer can take orders before another.
  • Debates about how many items arrived in a pallet when pictures of cardboard boxes are shared. Detailed discussion of packing systems including how many units are packed in a box.
  • First customer ship with a barrage of list traffic stating “Ordered mine today”.
  • Rigs start to arrive coupled with a few unboxing YouTube videos again lambasting the videographer for not showing specific features.
  • Discussions of the features as people learn about the radios and the naysayers stating, “The old model did it better so I will keep my old one”. One has to see the separate psychology paper on the thought process of how one dismisses a new model for the old when for some, buying the new one was not really in the cards anyway. One theory is it’s a way for one to justify to themselves their inability to buy a new one so casting aspersions on the newer model makes them feel better.
  • Barrage of reports stating “My radio arrived today” emails to various lists.
  • As more shipments arrive and operational limitations arise, a voracious discussion why feature A or B was included or left out. Another round of discussions on the economics of manufacturer scope decisions as a function of pricing in the desired market. Much input from retired experts that used to manage something similar for XYZ Corp.
  • The resident and highly valued test engineers run the new radio through its paces. These results are interpreted by the masses as either confirmation of the aforementioned biases towards the old radios compared to the new one or serve to confirm one’s decision to be an early adopter. Frequently another round of discussions about the need for a specific feature starts again.
  • The testing phase is closely coupled with countless discussions on the specifications of a feature that perhaps one in 1000 users of the new radio will ever use (i.e., setting the DSTAR position of a 9700 that never leaves the shack with a GPS versus simply entering in one’s non-changing Lat/Long manually). This highlights the point that the fact that a feature will not be used by most does not mean it cannot be debated ad infinitum.
  • The population generally settles down until the first radios have the inevitable failures of a few. Chastising those deemed foolish to be early adopters commences with the naysayers relishing in a ubiquitous round of “I told you so” and “This is why I wait to buy”.
  • First round of price drops with again another shot at the early adopters and then some lamenting they feel robbed that they paid 100 currency units more for a radio and their dealers are awful for not refunding the difference 6 months after the fact.

All the while, the various moderators of the lists try to weigh a careful balance of letting the group have their discussions and deciding when to shut down a discussion. Also note that these are not absolute rules. It is possible that one can raise a topic late in the game about currency exchange rates and prices (see active R&L Discussion on 9700 mailing list).

Building a Serious Field Day Satellite Station

I have been acquiring hardware for a serious portable satellite station for several years. I have used various setups at Field Day and Winter Field Day with irregular success.

Here is what I have so far:

  • Green Heron RT21 Az/El Rotor
  • Icom 9100 HF/VHF/UHF Satellite Radio
  • M2 LEO Pack Satellite Antennas
  • Yaesu G5500 Az/El Rotor
  • SSB Preamps for 2m and 440
  • Mac Doppler for radio and rotor control

One website I check out from time to time is the wonderful site of Fred [QRZ call=AB1OC] and Anita AB1QB. I first found this site when looking for ideas on building a shack. One of Fred’s projects has been building  a portable satellite station. As I read the list of equipment in Fred’s article, I realized I have just about the exact same equipment that he does. You can find that article here.

Regarding Field Day, one practice that works very well for Field Day planning is a dry-run. Several weeks before Field Day, we get all the radios, cables, computers, etc together and make it all works together. We then take it all apart, put it all in sealed bags or boxes and bring those exact same bags and boxes to Field Day. It eliminates many surprises at the event itself. It occurs to me that I do not do that same with the satellite setup. So this year, a different plan is on order.

Building on Fred’s project, I went ahead and ordered the Glen Martin 4.5 foot roof tower and sand bags. In May, I plan to get together with those interested and assemble the satellite station complete with antennas, preamps, coax and the rest of the gear. We will then make some contacts. I will work on the bits and pieces between now and then, but the goal is to both educate those interested in satellite operations as well as ensure we have a reliable satellite station for portable operations. This can be of use for Field Day, Winter Field Day and the St. Petersburg Science Festival in which SPARC participates. In the future, the antennas may change as I put some of this equipment up at home, but it will be similar.

If you are interested in helping out, I will advertise this to the usual SPARC/CARS and UPARC channels.

Radio Gear for Sale

Updated 8/4/2016 – Any items not crossed-out are still available.

I am selling some surplus gear. All prices are for local pickup. Actual shipping paid by the buyer. I could also meet in the Tampa Bay area.

  • Microham DB-37 cable for Icom $40
  • Microham USB sound card interface (with an icom cable) ($65)
  • Icom ID-1 1.2 Ghz Analog/DStar radio. Includes data mode via Ethernet connection to send 128kbs data via DStar. Have microphone, manuals and cables. I have a second one if you want to make a pair for a remote data app. ($550 each)
  • Icom 821H Dual-band 2m/440 base CW/SSB/FM radio (it has a quirk in that when you key there is a slight delay). ($400)
  • Icom ID-92AD dual band DSTAR radio. Included base charger $200

 

All radios have been tested on my HP8924C service monitor including output and receiver tests. If you come to see anything, I would be glad to fire it up into the analyzer and let you verify it works according to specs. You know, unless the analyzer sells first.

Station Building

I ran across a very good blog on building a station. This chap built it from soup to nuts including the room, adding A/C, generator, two contesting operating positions and more. There are many good ideas in his station building series. Look here for more.

Drake Twins C-Line

20121227-015532.jpgI just got these back from Ron Baker in Tennessee. Ron took them apart and put them back together as well as cleaned them throughly. He repainted the cases too. He did a very nice job, they sound great.

Icom 775DSP For Sale

The rig is sold.

 

I have an Icom 775 DSP (Serial #1185) for sale.

The rig is in great shape, works flawlessly and has ALL optional filters except for the AM filter. Internal Antenna tuner, 200 watts output, built-in power supply. Dual-Watch complete with 2 VFO knobs for ease of listening to the receive side of a pile-up. I have the manual, but no microphone as I use a headset.

I wil be taking to the Tampa Bay hamfest but I figured I would offer to fellow FCG’ers first.

Due to the filter complement, the price is $2000. Shipping is extra at actual cost from the shipping store.

I am selling simply as I have a Ten Tec Orion II and it seems silly to let this great radio go underutilized.

Don’t forget I also have the Ten-Tec Titan 425 1500 Watt amplifier for sale. It will be at the Tampa Bay hamfest too.
