Hi Dave, please take a look at this product: https://shop.kuhne-electronic.de/kuhne/de/shop/konverter-transverte/empfangskonverter/MKU+LNC+144++Empfangskonverter/?card=1779#_tab_content4 you might get some ideas by reading the documentation. Your receiver must be that well designed to cope with the ...

Congrats! In order to improve suppression of unwanted spurii, try adding a band pass between the transverter and the PA, e.g.

The cheap OWF filters cannot handle 30dBm.

In case of overdriving your mixer with too much 28MHz injection, 3rd harmonic will increase as well. It is up to you to adjust the input level of the mixer. You can use attenuators and/or reduce PA gain (increasing value). As a rule of thumb, do not exceed 0,1mW for a 7dBm mixer. Go for IM3 first (i...

Hi Dave, - as far as I remember the 70/28 transverter has a LPF at the Input, so this should add significant attenuation to the 3rd harmonic. - I don't have the 200D, but on all of my ANANs (10/100/7000) PA GAIN DOES HAVE AN EFFECT OF THE XVERT output!!! - IM3/IM5 are the figures to take care of at ...

Kjell,

my Orion MKII is part of my ANAN 7000DLE. I cannot imagine how to run Pure Signal with the transverter output (HF PA disabled).
To be honest, I was not even able to find the transverter output path in the schematics.

GALI? in my schematics Version 5.2 I find the PGA-103+ MMIC. When I checked the quality of the transverter output at 10dBm or higher I measured abt -25dBc, at 0dBm it was about -45dBc. I expected better values. Not I know why. :shock: Pure signal can hardly be used with transverters. TNX Volker DL4ZBG

Hi Dave, please take a look at my settings: https://apache-labs.com/community/viewtopic.php?f=36&t=3097&p=7615&hilit=transverter+dl4zbg#p7615 Don't forget the checkbox "XVRT" ! Without this one checked reception is "zero" "Out of band": change your region se...

Jeff, I am not quite shure whether this is is an issue of the ANAN hardware. I am using the 7000DLE. Increasing the PA settings in order to reduce the transverter output to 0dBm or even lower will lead to only 2 steps!! Absolutely not useable. To avoid this I increased the output level to abt 50mW a...

Please post your experiences and (if you have measuring devices) the IM3 values of the transmitter. On 4m large signal behaviour of the receiver might be less important.

Both transverters are rated at abt. +- 2ppm. I can live with their frequency drift (after warming up) quite well. For 432 I temporarily added this filter: https://www.ebay.com/itm/433MHz-Remote-control-model-aerial-map-pass-band-pass-filter-433M-bandwidth-8MHz/283483073477?ssPageName=STRK%3AMEBIDX%3...

Hi Dave, I have been playing around with a few of these little gadgets e.g.: https://www.ebay.com/itm/432mhz-to-28mhz-Transverter-high-linear-board-for-FLEX-RADIO-UHF-QRP-0-1-W-70cm/254447146297?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 https://www.ebay.com/itm/144-432-to-28-MHz...

Hi Ken,

I own both. Due to crosstalk issues on the old 100 PA board, predistortion will not work as well as it should.
My recommendation: sell the 100 and buy a new 7000 DLE (II).

Graeme,

of course I am using protocol 2.....

Hi Graeme,

using my 7000 DLE (no MKII) I can get abt. 0 dBm at a gain setting of 72. The output is very clean (IM3 abt -50dBc). Did you enable the checkboxes "XVERT RF TX" and "Disable PA" for your (hopefully) enabled transverter?

Scott, my station is only half SDR. I am using a Microham MK2R+ to manage my K3 and my ANAN (SO2R). So I have connected my ANAN (Thetis) to the Micromham router using COM1 of my PC (getting 2 virtual ports back via Microham USB connction and controlling my Ultrabeam antenna). Might sound a little bi...

Hello, during the last UHF Contest I was using my 7000DLE as an exciter for a new 70cm transverter (Thetis 2.7.0, Hardware Com port 9600 Baud to Microham device, MIDI DJControl Compact). Any time I was suffering from VFO overshooting when turning the VFO wheels quickly. Disabling CAT contol solved t...

Forget about OC, run serial using DDUTIL which can control SPE amps. I finally succeeded in coupling with my ACOM via DDUTIL.
No worries

Scott's hint (checkbox "DEMO/HPSDR" in DDUtil > Setup > Features) was all I needed. Works now, even with microham virtual port assignment. DDUTIL seems to be fixed to 9600 baud com port speed. Higher speed would be appreciated. Is there any chance to choose a different speed? TNX Volker

Sri, very busy with contest preparation, will test next week!

I could not get my 7000 DLE communicating with both mentioned versions of DDUtil either....

Steve,

I have problems on 40 as well while running legal limit....
my question:
did you keep the shielded leads AND the 0.22 caps or did you remove them?

thanks

Hello John, there might be some settings working well. I have chosen: ACOM CAT : Elecraft (38400) CAT+: CAT2 : choose your correctly wired hardware COM port, settings 38400 , N, 8, 1 and activate the power amplifier will follow the VFO A frequency ONLY in "Operate" not in "Standby&quo...

Hello experts of DDUTIL configuration, I have been running my 7000 DLE together with my 2000A via CAT+ using Thetis or (formerly) 3.4.9 mRX for a long time. Now I am experimenting with DDUTIL (Version 3.2.5). - what are the real settings on ACOM side and in DDUTIL? I cannot configure 1200 Baud in th...

Exactly!
I am using a Microham MK2R+ (internal Winkey chip) to key both my 7000DLE and my K3 in SO2R. An external PTT hardware contactor did never switch any of my ANANs into (CW) transmit mode. This would be highly appreciated....
As far as I remember, this is not a new discussion.

They used to send such mails.....

I tried this of course. Yesterday I was not able to edit these values. The edit window background became blue.....
Restarting Thetis 2day and it worked this time. Now the S- meter readings are correct.

Very funny.

Last weekend I successflly moved from P1 to P2 (Thetis 2.6.8 c5) with my 7000 DLE. Checking my S- meter readings with my XG3 I noticed that they were 8 dB too low. So I tried to perform a level calibration on 30m like I did "in the old world" (P1) with PSDRmRX. But I was only able to chang...

I forwarded my mail exchange with Apache to your Mail account. Please take a look at the infos.

Hello Roger,

yes, it's a new fan from NMB running at fixed speed. I am happy with it. As far as I've been told, all higher serial numbers of model 7000 DLE were supplied with this fan.
