ANAN 200D with Transverter

Postby g7pvs » Sun Apr 09, 2017 2:59 pm

Hi,
I thought I'd transfer this over from the email system as I would still like to know if it is possible to get it sorted (I've removed email addresses to avoid SPAMBOTS):

Hi,
On the General tab, I selected the Ant/Filters tab, then on the Antenna tab I ticked the XVTR box next to 10m.
What I had previously expected was for only the XVTR signal to be routed through to ADC1 when I selected a XVTR frequency, I wasn't sure how selecting the XVTR box for 10m would help, but figured I'd try it anyway.
I'm unsure what benefit there could be in leaving the main antenna inputs connected to ADC1 when a XVTR input frequency is selected, but I'm still quite new to using SDR radio.
Although not ideal I figured that as RX2 is only routed to ADC2 that was what I had to use unless I wanted to unplug or use an external switch for the HF antenna every time I wanted to change over to 4m.

Hi Again,

If I switch VFOA between 70MHz and 28MHz (should be the same frequency) with my HF antenna connected to ANT 1 and my transverter connected to RX2 (nothing connected to XVTR RX), with 70MHz selected although attenuated I'm still getting the 28MHz signals on VFOA.

This is with XVTR tick box selected next to 10m on antenna tab and in XVTR setup I've ticked 'XVTR RF TX' and 'Disable PA'.

On the antenna tab if I select ANT 2 for 10m, then the attenuated 28MHz signal present when 70MHz is selected almost completely disappears.

Is this what is intended to happen and if not is it common to all 200D radios?

Hi Trev , I'm also interested in this as I plan to get a 4m xtvr . Like you i'm seeing the ANT1 signal coming through when 4m is selected , thought this should be completely dead as there is nothing connected to xvtr port yet. Using Anan 100, my guess is I'm missing some setting or checkbox.

Hello All,
This is my first ever post.

My name is Adrian and I am an avid VHF/UHF/SHF-er. I bought a new Anan 200D back in January this year, my first experience with SDR, although I have been following the technology via QEX magazine..

Prior to this, (since 1981), I have been using Japan Radio Corp NRD515 rx and NSD515 tx as my 28-30MHz IF for ALL my VHF/UHF/SHF activity. This has been fantastic gear but, sadly, it s just about worn out. My new 200D is my first new radio in over 30 years! How technology has changed.

I thought the 200D would more or less just drop into my present system, and so it has. I have four transverters that are directly driven from 28-30MHz... 70MHz, 144MHz, 145MHz and 432MHz. Each has separate rx and tx ports on the input and output. On tx, I split the 28MHz into 4 with a Minicircuits 4 way splitter and drive each transverter with about 2.5mW. Each transverter has a gain pot, so any drive level between 1mW and about 1W is manageable. On receive I use a 4 way coax switch to select each transverter rx port. The 145MHz transverter is specially built, (home made), and has eight, (8), channels of tx output, about 50mW each. This transverter drives all the higher band transverters, 1296MHz to 10368MHz. (That's as high as i go so far but there is room for more).

I was a bit concerned when I started hearing comments that the Transverter output from the 200D was only 1mW. When I split that into 4, it would not be enough to drive each transverter, however, I had no trouble adjusting the 200D transverter output to 10mW (or more). I've attached screenshots of my relevant settings. Note the PA Gain settings for the VHF bands. Gain around 50dB produce output on the transverter tx port around 1mW. Gain around 40dB produce about 10mW out. Max out is 38.8dB which produced about 13mW.

To make the 200D frequency read correctly, the frequency offset must be set assuming 28-30MHz e.g 1296-28 = 1268MHz etc. even though it is 145-147MHz on all bands above 432MHz.

I hope this may be helpful.

73, Adrian. VK4OX.

ps. An extra screenshot of how I got the 200D TVR rx input port to accept 28-30MHz from the 144MHz Transverter. Note Disable Bypass tickbox ticked and the 10m XVTR tickbox also ticked.

Hi again,
Further to my previous post, I have been experimenting with the front panel Drive Slider. With the PA Gain set to max (38.8dB) on VHF bands (PA disabled) and the Drive Slider also set to max, I can get 25mW out of the 200D "XVTR Out" port on "Tune". The Drive Slider controls the output from 25mW right down to zero. With my "normal" setting of PA Gain 39.7, the Drive Slider can control XVTR port output from zero to about 21mW, so setting the PA Gain on VHF bands to 40dB should provide 0-20mW out on the 200D XVTR port, controlled via Drive Slider on the front panel.
