Happy St. Pat's day to all...

v2.9.0.8 x64 working well here.

To Richie, Ernst and others involved in the latest Thetis update, many thanks for your dedication and time spent in giving us this great software.

In the FWIW department: IMHO the ANAN mic input should never have included capability for a PTT connection, it has proven to be nothing but trouble for a lot of people. Nevertheless that's what we are stuck with and things have to be wired up correctly in order for it to work right. One issue is th...

If you've done any programming and have a rudimentary grasp of these sort of tools but not these exact tools (I'd put myself in this category) I'd say it was around a 4 or 5 on the difficulty scale, mostly because you know enough to know what you want and get impatient learning the tools to get the...

I built the latest that was posted yesterday. At least I think I did, I'm not fully up to speed on pulling down Git updates, etc. Hi Scott, How difficult was the bar graph meter update? While we await a full installer version, do you have any tips to share or care to offer step-by-step instructions...

Scott's right. It's not a permanent fixture and only used long enough to test OC ports. A battery fastened to the jig is fine and would last the shelf life of the battery.

You're probably right, Paul! If there's a resistor laying around, then there might an LED, too! Heck, if you didn't have anything at all, you could just buy some cheap automotive, 12V LED indicators off of Amazon, the kind with the built in resistor, and use those. Red lead to +12V, black lead to a...

Then how about even simpler with no test gear?

From the OC pin, connect a 680 Ω resistor in series with a standard red LED, anode side to +12V. It's not a measurement, but it does indicate if the OC is functioning correctly.

Paul, W9AC

cant seem to get ANY results measuring with an ohm meter for opens and shorts as well as the volt meter for any voltage changes between gnd and any of the pins... I may just not understand the implementation... I typically understand open collector to mean that one of the OC input pins would likely...

See the post below from 2017. I once had a similar issue when using an early version of Thetis. It could be completely unrelated, but I think it's worth investigating Ethernet port grounding and quality of Ethernet cabling, especially if you're using a multiport Ethernet switch: https://community.ap...

Awesome effort.

Richie, is it your current plan to display all functions simultaneously or menu-select only those metering parameters of interest to the operator?

I'm pretty sure a 1N4007 is not a PIN diode. I would be surprised if this technique isn't widespread among commercial manufacturers. (Sadly, not Apache Labs.)... Help may be forthcoming: https://community.apache-labs.com/viewtopic.php?f=46&t=4494 And John is correct: modern 1N4007 diodes have a...

A recently acquired schematic of the ANAN 7000 PA/LPF board shows complete elimination of the T/R relay with substitution of a relatively complex PIN diode RF circuit. A total of nine S1M PIN diodes (1KV PIV) manage RF switching. Four BSS84 switching MOSFETs control diode activation bias. It would b...

LCD monitors mount onto a 60-inch steel arc at eye level. Vertical compartment boards also float between desktop and ...

Looks like Warren's patch may include an update to Envelope Elimination & Restoration (EER). If an update was included, are any folks in the community experimenting with EER-compliant amplifiers?

Attached are frequency response plots from my ANAN 7000 with ASIO VAC engaged and measured with SpectraPlus-SC software. SpectraPlus-SC has a built-in ASIO driver. Both measurements were taken with a 4096 filter size in LSB mode, 5 kHz receive bandwidth, no weighting, and peak-hold sweep mode (red-c...

And it would appear that I've got no modulation on transmit. I'm using VAC. Does FM work with VAC? FWIW - VAC in FM mode works here with the WDM driver, but not ASIO. However, I am using a modified ChannelMaster.dll file and have full FM audio control and metering with ASIO. I only engage VAC for d...

FM audio sounds good here. Of course, it's bandwidth-limited but I don't hear any obvious distortion, artifacts, nor data breakups. The signal source is an Icom 7610 in FM mode transmitting into a dummy load. Icom audio input source: USB 3.0 sound interface and a studio-grade mic. Thetis FM DSP sett...

W6MY - GPS Setup.rtfPaul, Thanks for sharing your configuration parameters. I setup my unit to match yours. How are you using the 48K output? Thanks Again, The 48 kHz output is used as a Word Clock generator to synchronize the data transfer between 48 kHz-sampled devices. Word Clock is a data synch...

Chip,

With the 2-port Bonar unit, it's a good idea to ensure that the port you've designated as 10 MHz has the correct setup parameters. I've attached a print-screen of my setup menu which shows 10 MHz on port 1 and 48 kHz on port 2.

Three weeks ago, I received an RF-Kit RF2K-S amplifier. 2T IMD performance compares favorably with my Alpha and ACOM tube amps and about 10 dB better than my SPE 1K-FA amp. The attached images show typical 2T IMD at 1500W from the RF-Kit amp using an Xtronic coupler. I don't normally use it and pref...

The Red Pitaya code provided by Pavel can already control an external LPF/BPF... likely you would use I2C. The original design was built to control ALEX! When the Codec comes along, the ALEX port is replaced by the I2S port, but I2C is also available. There have been several solutions with I2C cont...

This looks like a much better choice for an amplifier: https://www.ebay.com/itm/334454204211 To be effective as a 10W transceiver, it needs a switched LPF after the amp in order to meet harmonic spectral purity requirements. That can be accomplished with manual switching, and possibly automatically...

Ron, Although I can't be of much help, I've attached a screen capture of my Ant/filters menu. It hasn't changed while operating ever since saving the profile under the "Transmit Profiles" menu. Possibly try to create a new profile name, then save it and see what happens. If that fails, the...

Sigi, FYI - Overwriting existing files with "Thetis-installfolder-files.zip" works fine. However, I found that "Thetis-v2.9.0.x64.msi," the full installer file, does not render the cross meter, even after renaming the .PNG file. Apart from that, it's working well. Many thanks! Pa...

Thank you, Sigi.

No TX meter here either. Missing image file? Screen capture below shows unknown open black space below S-Meter.

Sigi, thanks for bringing this to our attention. I was beginning to question my ability to grab files from github! Any idea when it will re-post?

Update: so far, so good with the new Dialight LEDs. I recently had a similar experience with a Yaesu FT-7250DR 2m/70cm transceiver. Yaesu uses ultra-bright white LEDs for LCD and panel button back-lighting. The rig stays on 24/7 and it's mostly used for System Fusion contacts. After three years, the...

Juha, I have an RF-KIT on order. Delivery should be in 4-6 weeks. I had to purchase the amp with no less than a 13 dB input pad but I'll be replacing it with 2 or 3 dB. My ANAN 7000DLE has been modified with an SMA RF relay that routes power from Orion to the RF-KIT amp. My goal is to reach 1KW in o...

"Q4: I recall seeing Scott recommending that I should be hitting the ALC hard and that I should see "ALC Group" figures of 0dB on a consistent basis and perhaps even +3dB at times. " I agree with that correction: +3 dB peaks allowed on ALC Group with +3 dB Max Gain set in the AG...
