KG-1000G Plus to/from KG-905G

[WSFR966]

Hi All - new to GMRS radios and have been struggling with testing range. I have an kg100g+ with an antenna mounted about 25' above the ground. When i test coms with the kg905g at 2miles, the transmission from the handheld to the kg-1000g+ comes in clear. However, the problem is when i transmit from the kg-1000g+ to the handheld it doesnt come thru or all static. I check the sql and its at 2. I tried different antennas, check both power and SWR, everything seems fine. I'm confused because if the handheld can reach the kg-1000g+ how can the kg-1000g+ transmission not reach the handheld?  please help.

It's most likely NOT a Wouxun issue. The negativity is getting old.

@WSFR966 What antenna are you using with the KG-1000G? And how far away are you when you try to use the HT? Do you have a clear line of sight?

I run a Wouxun in th shack and vehicle along with Wouxun HT's and don't have any problems. I am running a Comet CA-712EFC base antenna, a Tram 1174 on my vehicle and the stock rubber duck antennas on my HT.

Tried 2 different antennas, first with a ano-50g and then a yagi 6 element. Both antennas were good on power and swr. According to scadacore I have good line of sight. Its a suburban area with trees

@WSFR966 do you have a tone set on the RX of the 905?

No tone set

So the kg-905g is transmitting into a low gain antenna that transmits in all directions.  I don’t know what your range is (same two miles or closer in?) but a Yagi is a poor antenna to use for anything other than a clear shot directly to another antenna.  And I am not familiar with the ano-50g, but in trees like that I would be much more inclined to try a low gain antenna on the kg-1000g. That will let the signal radiate in all directions like the antenna on the 905 does.

For reasons mentioned by @SteveShannon the Yagi may not be your best choice for this situation. I think the ano-50g needs a ground plane, if you don’t have one you may want to try a different antenna. It sounds like you are set up for a base station.

I did try a ground plane, no change in results, the yagi I thought might be good as a directional type to reach further.

Radio is funny and rules of thumb sometimes are never right for all situations.  A Yagi should make you reach further, but because it limits the various other paths the RF may take I think it’s actually self-defeating in this situation. Try an omnidirectional antenna at ground level. After all, your 905 works at ground level with 1/10th as much power.  Putting your antenna at 25 feet might simply be placing it at just the right level that the trees can block RF.

Thanks all for your input, all good things for me to try. Still puzzling because when the hand held can reach the base station clear but the higher power base station can’t reach the handheld it’s confusing.

I truly believe it’s going to be the height and type of the antenna.  Your antenna is at 25 feet. You’re surrounded by trees. Their canopies are probably about 25 feet.  Any high gain antenna concentrates its power in a flatter pattern than an omnidirectional antenna. A Yagi also concentrates it in a narrow cone.  Trees will absorb the signal. High gain directed into trees leaves little signal in other directions.  Lowering the antenna to ground level might allow it to send the RF below the tree canopies.

Also, ,are sure the 1050 is transmitting wideband.

Sounds like another woxoun issue.  From what i have seen over the years first hand the kg1000 and all woxouns have issues like this.
